🧹 Outside diff range and nitpick comments (30)
packages/multi-format/src/encryption/kms-format.ts (2)
5-7: Enhance class documentationThe current documentation is minimal. Consider adding:
- Purpose and use cases for KMS encryption
- How this integrates with Lit Protocol
- Examples of usage
- Any requirements or prerequisites
Example enhancement:
/** * Class to serialize and deserialize multi-format KMS encrypted data + * + * This class handles Key Management Service (KMS) encrypted data within the multi-format framework. + * It integrates with Lit Protocol for decentralized key management. + * + * @example + * const kmsFormat = new KMSMultiFormat(); + * // Example usage with encryption/decryption */
9-11: Consider adding input validationThe constructor accepts no parameters but uses specific encryption constants. Consider adding runtime validation to ensure the encryption type constants are properly configured in the environment.
constructor() { + if (!MultiFormatTypes.prefix.KMS_ENCRYPTED || !EncryptionTypes.METHOD.KMS) { + throw new Error('KMS encryption constants are not properly configured'); + } super(MultiFormatTypes.prefix.KMS_ENCRYPTED, EncryptionTypes.METHOD.KMS); }packages/types/src/epk-provider-types.ts (2)
1-3: Consider using type-only imports for better performanceSince this is a TypeScript type definition file, we should use type-only imports to ensure these imports are removed during compilation.
-import { CypherProviderTypes } from '.'; -import * as Encryption from './encryption-types'; -import * as Identity from './identity-types'; +import type { CypherProviderTypes } from '.'; +import type * as Encryption from './encryption-types'; +import type * as Identity from './identity-types';
5-10: Enhance documentation and type safetyThe interface could benefit from more detailed JSDoc documentation and stricter type definitions.
-/** EPK provider interface */ +/** + * EPK (Encryption Provider Key) interface that defines the contract for encryption providers. + * Extends the base cipher provider to add support for identity-based encryption methods. + */ export interface IEpkProvider extends CypherProviderTypes.ICypherProvider { - supportedMethods: Encryption.METHOD[]; - supportedIdentityTypes: Identity.TYPE[]; + /** List of encryption methods supported by this provider */ + readonly supportedMethods: readonly Encryption.METHOD[]; + /** List of identity types supported by this provider */ + readonly supportedIdentityTypes: readonly Identity.TYPE[]; + /** + * Checks if the given identity is registered with the encryption provider + * @param identity - The identity to verify + * @returns Promise resolving to true if the identity is registered + */ isIdentityRegistered: (identity: Identity.IIdentity) => Promise<boolean>; }packages/types/src/encryption-types.ts (1)
Line range hint
1-32: Documentation update needed for KMS method.Since we're adding a new encryption method, we should ensure it's properly documented.
Consider adding JSDoc comments to explain the KMS method in the enum, similar to this:
/** Supported encryption methods */ export enum METHOD { + /** Key Management Service (KMS) encryption using Lit Protocol */ KMS = 'kms', ECIES = 'ecies', AES256_CBC = 'aes256-cbc', AES256_GCM = 'aes256-gcm', }packages/types/src/cypher-provider-types.ts (2)
1-4: Enhance interface documentation with security considerationsWhile the documentation provides a basic overview, it should include:
- Security considerations and best practices
- Expected encryption standards/algorithms
- Error handling expectations
Add additional documentation:
/** * A generic interface for Key Management Service (KMS) providers. + * + * Security Considerations: + * - Implementations should use strong encryption algorithms + * - All errors should be caught and handled appropriately + * - Sensitive data should be properly sanitized before encryption + * - Memory should be cleared after encryption/decryption operations + * + * @throws {Error} When encryption/decryption operations fail */
1-20: Consider adding validation methods to the interfaceSince this interface is crucial for encryption operations, consider adding methods for validating encryption/decryption parameters.
Consider adding these methods to the interface:
/** * Validates encryption parameters before operation */ validateEncryptionParams(data: T, options: EncryptionOptions): void | never; /** * Validates decryption parameters before operation */ validateDecryptionParams( encryptedData: EncryptedData, options: DecryptionOptions ): void | never;This would ensure consistent validation across different implementations and improve security.
packages/types/src/index.ts (1)
6-6: Consider standardizing the spelling of 'Cypher' to 'Cipher'.While the code is functionally correct, the spelling 'Cypher' is non-standard in cryptography contexts where 'Cipher' is more commonly used. However, if this is an intentional choice across the codebase, please disregard this comment.
Also applies to: 10-10, 26-26, 30-30
packages/request-client.js/src/http-request-network.ts (1)
Line range hint
20-33: Add JSDoc documentation for cypherProvider parameterThe constructor's JSDoc comments should include documentation for the new
cypherProviderparameter to maintain consistency with other parameters.Add the following line to the JSDoc:
* @param options.signatureProvider Module to handle the signature. If not given it will be impossible to create new transaction (it requires to sign). * @param options.currencies custom currency list. * @param options.currencyManager custom currency manager (will override `currencies`). * @param options.skipPersistence allows creating a transaction without immediate persistence. + * @param options.cypherProvider Module to handle encryption operations using Lit Protocol. */packages/transaction-manager/README.md (3)
23-23: Documentation enhancement needed for Lit Protocol integrationWhile the import statement is correctly updated, considering this PR's objective of adding Lit Protocol support, it would be beneficial to include an example demonstrating the Lit Protocol integration alongside the existing ECIES example.
Consider adding a section like:
### Using Lit Protocol for encryption ```javascript import { LitProtocolProvider } from '@requestnetwork/lit-protocol'; // Example setup and usage of Lit Protocol provider--- `114-114`: **Consider adding a security notice about private keys in examples** While the import statement is correctly updated, the examples throughout the documentation use hardcoded private keys. Consider adding a security notice warning users against using hardcoded keys in production. Add a notice like: ```markdown > **Security Notice**: The private keys shown in these examples are for demonstration purposes only. Never use hardcoded private keys in production code.
Line range hint
1-1: Documentation needed for new featuresThe README is missing documentation for two major features mentioned in the PR:
- Lit Protocol integration and its configuration
- Capacity credits delegation functionality
Consider adding sections that cover:
- How to configure and use the Lit Protocol provider
- How capacity credits delegation works and its setup
- Any new parameters or options related to these features
Would you like assistance in drafting these new documentation sections?
packages/request-node/src/requestNode.ts (2)
164-167: Update NOT_FOUND_MESSAGE constantThe route registration looks good, but please update the
NOT_FOUND_MESSAGEconstant to include the new/getLitCapacityDelegationAuthSigendpoint in the list of available endpoints.export const NOT_FOUND_MESSAGE = - 'Not found\nAvailable endpoints:\n/POST persistTransaction\n/GET getTransactionsByChannelId\n/GET getChannelsByTopic\n/POST /ipfsAdd\nGET getConfirmedTransaction\nGET status'; + 'Not found\nAvailable endpoints:\n/POST persistTransaction\n/GET getTransactionsByChannelId\n/GET getChannelsByTopic\n/POST /ipfsAdd\nGET getConfirmedTransaction\nGET status\nGET getLitCapacityDelegationAuthSig';
Line range hint
1-195: Consider error handling and rate limitingSince this endpoint is part of the authentication flow for Lit Protocol capacity delegation, consider implementing:
- Rate limiting to prevent abuse
- Appropriate error handling and status codes
- Request validation middleware
- Logging of authentication attempts (success/failure)
This will help ensure the security and reliability of the Lit Protocol integration.
packages/transaction-manager/src/channel-parser.ts (1)
Line range hint
195-201: Consider enhancing error handling specificityWhile the optional chaining improves robustness, consider making the error handling more specific:
- Extract the error message prefix to a constant
- Add type narrowing for the error object
- Consider logging the encryption method for debugging
+const DECRYPT_ERROR_PREFIX = 'Impossible to decrypt the channel key from this transaction'; + +interface DecryptionError extends Error { + message: string; +} + if ( - error?.message?.startsWith( - 'Impossible to decrypt the channel key from this transaction', - ) && + error instanceof Error && + error.message.startsWith(DECRYPT_ERROR_PREFIX) && result.channelType === TransactionTypes.ChannelType.UNKNOWN ) { result.channelType = TransactionTypes.ChannelType.ENCRYPTED; result.encryptionMethod = timestampedTransaction.transaction.encryptionMethod; + console.debug(`Channel encryption method set to: ${result.encryptionMethod}`); }packages/transaction-manager/src/transaction-manager.ts (1)
22-31: Consider architectural improvements for encryption handlingTo improve the robustness of the encryption integration:
- Add JSDoc comments explaining the cypherProvider's role and requirements
- Consider implementing a consistent error handling strategy for encryption operations
- Add logging for encryption operations to aid debugging
- Consider implementing a provider capability check method
Example documentation:
/** * Optional encryption provider implementing ICypherProvider interface. * Used for encrypting new transactions and managing encryption keys. * @see ICypherProvider for implementation requirements */ private cypherProvider?: CypherProviderTypes.ICypherProvider;packages/request-client.js/src/http-data-access.ts (1)
208-212: Enhance method documentationThe JSDoc comments should provide more details about:
- The purpose of capacity delegation
- The format and requirements for delegateeAddress
- The structure of the returned AuthSig
- Possible error scenarios
/** * Gets the Lit Protocol capacity delegation auth sig from the node through HTTP. * - * @param delegateeAddress the address of the delegatee + * @description Retrieves an authorization signature for Lit Protocol capacity delegation. + * This allows the delegatee to use the delegator's capacity credits for encryption/decryption. + * + * @param delegateeAddress The Ethereum address of the account receiving the delegation + * @returns Promise<DataAccessTypes.AuthSig> The authorization signature object + * @throws {Error} If the delegateeAddress is invalid or the request fails + * @throws {Error} If the node is unable to generate the authorization signature */packages/epk-cypher/test/ethereum-private-key-cypher-provider.test.ts (2)
153-170: Enhance encryption test coverageThe encrypt test suite only covers the happy path. Consider adding tests for:
- Edge cases (empty data, large data)
- Error scenarios (invalid encryption parameters)
- Different data types
Example test case:
it('should handle empty data encryption', async () => { const decryptionProvider = new EthereumPrivateKeyCypherProvider(id1Raw.decryptionParams); const emptyData = ''; const encryptedData = await decryptionProvider.encrypt(emptyData, { encryptionParams: id1Raw.encryptionParams, }); expect(encryptedData.value.length).toBeGreaterThan(0); expect( await decryptionProvider.decrypt(encryptedData, { identity: id1Raw.identity, }), ).toEqual(emptyData); });
64-64: Improve test descriptions for better clarityThe test descriptions could be more specific about what they're testing. Consider using a more descriptive format: "should [expected behavior] when [condition]"
Examples:
-it('cannot construct with decryption parameter not supported' +it('should throw error when constructing with unsupported decryption method' -it('cannot addDecryptionParameters if method not supported' +it('should throw error when adding decryption parameters with unsupported method' -it('cannot decrypt if encryption not supported' +it('should throw error when decrypting data with unsupported encryption method'Also applies to: 103-103, 127-127, 188-188, 199-199, 211-211
packages/request-client.js/src/api/request-network.ts (1)
53-67: Consider implementing a CypherProvider factoryThe current implementation allows for flexible cypher provider injection, which is good. However, as this is part of the Lit Protocol integration, consider implementing a factory pattern for cypher providers to:
- Standardize provider creation
- Encapsulate provider-specific configuration
- Make it easier to add more providers in the future
This would improve modularity and make the integration of new encryption providers more straightforward.
packages/request-node/src/request/getLitCapacityDelegationAuthSig.ts (1)
46-49: Use a more appropriate HTTP status code when no tokens are foundReturning
UNPROCESSABLE_ENTITY (422)when no existing tokens are found may not accurately represent the error condition. Consider usingNOT_FOUND (404)orBAD_REQUEST (400)to better reflect the situation.packages/epk-cypher/src/ethereum-private-key-cypher-provider.ts (3)
15-15: Typo in comment: 'method' should be pluralized to 'methods'In the comment on line 15, "list of supported encryption method" should be "list of supported encryption methods" for grammatical correctness.
58-63: Improve type definitions in 'decrypt' method parametersCurrently, the
decryptmethod'soptionsparameter is implicitly typed. Explicitly defining its type enhances clarity and type safety.Consider updating the method signature:
- public async decrypt( + public async decrypt( encryptedData: EncryptionTypes.IEncryptedData, options: { identity: IdentityTypes.IIdentity; }, ): Promise<string> {Alternatively, define an interface for
optionsif it will be reused.
90-94: Optimize 'isIdentityRegistered' method by checking the map directlyInstead of iterating through all keys, you can directly check if the identity exists in the map. This increases efficiency.
Apply this diff for optimization:
public async isIdentityRegistered(identity: IdentityTypes.IIdentity): Promise<boolean> { - return Array.from(this.decryptionParametersDictionary.keys()).some( - (address) => identity.value.toLowerCase() === address.toLowerCase(), - ); + return this.decryptionParametersDictionary.has(identity.value.toLowerCase()); }packages/transaction-manager/src/transactions-parser.ts (1)
142-142: Rename 'encryptResponse' to 'encryptedChannelKey' for clarityThe variable
encryptResponseholds the encrypted channel key data that needs to be decrypted. Renaming it toencryptedChannelKeyimproves readability and more accurately reflects its purpose.Apply this diff to rename the variable:
-const encryptResponse = JSON.parse(MultiFormat.deserialize(entries[0][1]).value); +const encryptedChannelKey = JSON.parse(MultiFormat.deserialize(entries[0][1]).value); ... -channelKey = await this.cypherProvider.decrypt(encryptResponse, { +channelKey = await this.cypherProvider.decrypt(encryptedChannelKey, { encryptionParams, });packages/lit-protocol-cypher/src/lit-protocol-cypher-provider.ts (2)
195-226: Reuse access control conditions when encrypting data.The
encryptmethod constructs access control conditions each time it's called. If the encryption parameters remain the same, consider caching the access control conditions to improve performance.
248-250: Provide a method to obtain session signatures if not already available.In the
decryptmethod, ifthis.sessionSigsis null, an error is thrown. Consider prompting the user to establish a session or automatically initiating the session signature retrieval process.packages/transaction-manager/src/transactions-factory.ts (3)
128-129: Provide More Informative Error Message WhencypherProviderIs MissingThe error message
'No cypher provider given'may not clearly indicate the requirement. Enhance the error message to specify that acypherProvideris necessary when encryption parameters use the KMS method.Apply this diff to improve clarity:
- throw new Error('No cypher provider given'); + throw new Error('Cypher provider is required when using KMS encryption method');
92-96: Add Error Handling for Encryption FailuresCurrently, if the
encryptfunction throws an error, it will propagate up the call stack. Consider wrapping the encryption calls in try-catch blocks to provide more informative error messages and handle exceptions gracefully.Example adjustment:
- const encryptedKey: EncryptionTypes.IEncryptedData = await encrypt( - symmetricKey, - encryptionParam, - ); + let encryptedKey: EncryptionTypes.IEncryptedData; + try { + encryptedKey = await encrypt(symmetricKey, encryptionParam); + } catch (error) { + throw new Error(`Failed to encrypt key for identity ${multiFormattedIdentity}: ${error.message}`); + }Also applies to: 221-225
82-97: Optimize Asynchronous Encryption Parameter MappingMapping over
encryptionParamswith anasyncfunction and then usingPromise.allis correct but could be optimized for readability. Consider using synchronous mappings if possible or abstracting this into a separate utility function.Also applies to: 208-227

packages/multi-format/src/encryption/kms-format.ts (1)
8-12: Verify the completeness of the KMS implementation
The class currently only provides basic initialization without additional methods for encryption/decryption operations. Let's verify if this minimal implementation is sufficient.
packages/types/src/epk-provider-types.ts (2)
6-10: Well-structured interface design
The interface effectively extends ICypherProvider and clearly defines the contract for EPK providers. The separation of supported methods, identity types, and registration verification aligns well with the PR's objective of implementing Lit Protocol encryption.
6-6: Verify ICypherProvider interface implementation
Let's ensure the base interface exists and contains the required encryption methods.
✅ Verification successful
ICypherProvider interface is properly defined with encryption methods
The ICypherProvider interface exists in packages/types/src/cypher-provider-types.ts and contains the required encryption methods:
encrypt(data: any, options: any): Promise<any>decrypt(encryptedData: any, options: any): Promise<any>
The interface extension in IEpkProvider is valid and correctly inherits these encryption capabilities.

5-5: LGTM! Import follows the established pattern.
The import statement follows the existing pattern of importing format implementations.
8-8: Verify KMSMultiFormat implementation and format order.
The addition of KMSMultiFormat as the first format in the array could have implications for format selection. Let's verify the implementation details and format selection logic.
Consider documenting the format selection strategy and the rationale for placing KMSMultiFormat first in the array. This ordering might affect which format gets selected when multiple formats are available.

27-27: LGTM! Verify impact on existing consumers.
The addition of the KMS method to the enum follows consistent naming patterns. However, as this is a type change, we should verify its impact.
Let's check for direct enum usage in the codebase:
✅ Verification successful
Let me try a different approach to search for the usage patterns:
Based on the search results, I can now provide a final response:
KMS method addition is safe and follows established patterns
The addition of the KMS method to the encryption types follows the existing patterns and is properly integrated:
- The enum value uses consistent naming (uppercase
KMS) - The string value follows the pattern (lowercase
'kms') - The KMS method is already being used in the codebase:
- In transaction-manager for hybrid encryption:
${EncryptionTypes.METHOD.KMS}-${EncryptionTypes.METHOD.AES256_GCM} - Has dedicated format handling in
packages/multi-format/src/encryption/kms-format.ts - Proper error handling for method validation exists
- In transaction-manager for hybrid encryption:
The change is non-breaking since:
- It's an enum extension (additive change)
- Existing code explicitly checks for supported methods
- KMS handling is properly isolated in dedicated components

4-20: 🛠️ Refactor suggestion
Improve type safety with generic parameters and specific types
The interface uses any types extensively, which bypasses TypeScript's type checking benefits. Consider using generic types and defining specific option interfaces.
Consider this implementation:
-export interface ICypherProvider {
+export interface EncryptionOptions {
+ // Add specific encryption options
+ algorithm?: string;
+ keySize?: number;
+}
+
+export interface DecryptionOptions {
+ // Add specific decryption options
+ algorithm?: string;
+}
+
+export interface ICypherProvider<T = unknown> {
/**
* Encrypts the given data.
* @param data - The data to encrypt.
* @param options - Any additional options required for encryption.
* @returns A Promise that resolves to an object containing the encrypted data and any necessary metadata.
+ * @throws {Error} If encryption fails
*/
- encrypt(data: any, options: any): Promise<any>;
+ encrypt(data: T, options: EncryptionOptions): Promise<{
+ encryptedData: string;
+ metadata: {
+ algorithm: string;
+ version: string;
+ [key: string]: unknown;
+ };
+ }>;
/**
* Decrypts the given encrypted data.
* @param encryptedData - The encrypted data to decrypt.
* @param options - Any additional options required for decryption.
* @returns A Promise that resolves to the decrypted data.
+ * @throws {Error} If decryption fails
*/
- decrypt(encryptedData: any, options: any): Promise<any>;
+ decrypt(
+ encryptedData: {
+ encryptedData: string;
+ metadata: {
+ algorithm: string;
+ version: string;
+ [key: string]: unknown;
+ };
+ },
+ options: DecryptionOptions
+ ): Promise<T>;
}This change:
- Introduces type safety with generics
- Defines specific option interfaces
- Adds structured return types
- Documents error cases

17-18: Consider updating documentation for the new format.
While the inline documentation is clear, consider updating any relevant README files or API documentation to include details about:
- The KMS encryption format structure
- How it relates to the Lit Protocol integration
- Migration guidelines for existing users
Let's check for documentation files that might need updates:

fd -e md -e mdx | xargs rg -l "encryption|format|prefix"17-18: LGTM! Verify prefix uniqueness.
The new KMS encrypted data prefix follows the existing pattern and is logically grouped with other encryption methods.
Let's verify that '05' isn't used elsewhere in the codebase:
✅ Verification successful
This should help us find any potential conflicts with the '05' prefix across the codebase, including both direct string literals and enum values.
✅ Prefix '05' is unique and correctly placed
The prefix '05' for KMS_ENCRYPTED is only used in multi-format-types.ts and follows the sequential numbering after AES256_GCM_ENCRYPTED ('04'). No conflicts found in the codebase.

75-76: Verify compatibility with major TypeChain version updates
The significant version jumps in TypeChain-related packages (@typechain/ethers-v5, @typechain/hardhat, and typechain) might introduce breaking changes that could affect type generation for smart contracts.
Let's verify the impact and compatibility:
Consider:
- Review the migration guides for breaking changes
- Ensure all TypeChain-generated files are regenerated after the upgrade
- Verify that the types work correctly with ethers v5 (since @typechain/ethers-v5 is being used)
Also applies to: 87-87
✅ Verification successful
TypeChain upgrade appears safe to proceed
The verification shows a well-configured TypeChain setup:
- TypeChain is properly configured in hardhat.config.ts with ethers-v5 target
- Generated types are managed through build scripts with proper cleaning
- No direct TypeChain imports in the codebase besides configuration
- Types are generated to
src/typesand copied to appropriate locations during build
The upgrade should work smoothly as:
- The project uses standard TypeChain configuration
- Build scripts handle type generation and cleanup appropriately
- The ethers-v5 target matches the TypeChain package being used

35-35: LGTM! Implementation aligns with PR objectives
The addition of the optional cypherProvider parameter is well-structured and follows the existing patterns in the codebase. The implementation correctly:
- Adds the parameter to the constructor
- Properly types it with
CypherProviderTypes.ICypherProvider - Passes it through to the parent class
Let's verify the integration with the parent class:
Also applies to: 45-45, 76-76
✅ Verification successful
Implementation verified - cypherProvider correctly integrated
The verification confirms that:
- The parent
RequestNetworkclass properly acceptscypherProviderin its constructor parameters - The
cypherProvideris correctly passed to theTransactionManagerwhere it's utilized - The inheritance chain from

The private member variable declaration follows the established pattern and is properly grouped with other handler declarations.
79-81: Verify handler dependencies
The handler is initialized with only the logger parameter, while other handlers in the class receive additional dependencies. Please verify that the GetLitCapacityDelegationAuthSigHandler doesn't require access to dataAccess or other services for capacity delegation functionality.
✅ Verification successful
Based on the handler implementation shown in the results, I can now generate the final response:
Handler dependencies are correctly configured
The GetLitCapacityDelegationAuthSigHandler only requires the logger dependency as it:
- Uses external clients (
LitContracts,LitNodeClient) that are instantiated within the handler - Retrieves configuration via the global
configobject - Does not need access to data stores or other services
The current initialization with just the logger parameter is appropriate for its functionality.

Line range hint 141-141: Address the TODO comment about removing channelId parameter
The TODO comment suggests removing the channelId parameter, but this needs verification before removal.
Let's check the usage of this parameter:
✅ Verification successful
Let me analyze the results and generate additional verification scripts to ensure we have a complete picture.
The channelId parameter can be safely removed
The verification shows that:
- The parameter is already prefixed with
_indicating it's unused - No references to
_channelIdexist within the method implementation - The parameter is only documented in JSDoc but not used in the logic
- All calls to this method pass the
channelIdbut don't depend on any return value related to it

The constructor changes look good and maintain backward compatibility. However, we should verify that all instantiations of TransactionManager have been updated appropriately.
Also applies to: 30-31
✅ Verification successful
All constructor calls are correctly updated
The verification shows that all instantiations of TransactionManager across the codebase are correctly using the constructor parameters:
- Test files appropriately use both single-parameter (dataAccess) and two-parameter (dataAccess, decryptionProvider) versions
- Usage examples demonstrate correct usage with both encrypted and clear requests
- The only instance passing the new cypherProvider parameter is in request-client.js, which is the expected implementation

27-27: Add JSDoc for the cypherProvider parameterThe constructor changes look good, but the cypherProvider parameter should be documented in the constructor's JSDoc.
Add the following to the constructor's JSDoc:
/** * @param dataAccess The data access implementation * @param decryptionProvider Optional decryption provider + * @param cypherProvider Optional cipher provider for encryption operations */Also applies to: 30-31
62-64: Enhance error handling for encryption operationsWhile the basic error handling is good, consider these improvements:
- Add similar error handling for existing encrypted channels
- Make the error message more specific about the context
if (encryptionParams.length === 0) { // create a clear channel transaction = await TransactionsFactory.createClearTransaction(transactionData); } else { if (!this.cypherProvider) { - throw new Error('Encryption requested but no cypherProvider available'); + throw new Error('Cannot create new encrypted channel: no cypherProvider available'); } // create an encrypted channel transaction = await TransactionsFactory.createEncryptedTransactionInNewChannel( transactionData, encryptionParams, this.cypherProvider, ); channelEncryptionMethod = transaction.encryptionMethod; }And for existing encrypted channels:
if (channelType === TransactionTypes.ChannelType.ENCRYPTED) { if (!channelKey) { throw new Error(`Impossible to decrypt the channel key of: ${channelId}`); } + if (!this.cypherProvider) { + throw new Error(`Cannot add to encrypted channel ${channelId}: no cypherProvider available`); + } transaction = await TransactionsFactory.createEncryptedTransaction( transactionData, channelKey, encryptionParams, + this.cypherProvider, ); channelEncryptionMethod = encryptionMethod; }Also applies to: 69-69

* @param encryptionParams Array of the encryption parameters to encrypt the key with + * @param cypherProvider Optional provider for encryption operations (e.g., KMS) * @returns the encrypted transactionAlso applies to: 170-170
127-129: Enhance error message for missing cypherProviderThe error message could be more specific about the context in which the cypherProvider is required.
- throw new Error('No cypher provider given'); + throw new Error('cypherProvider is required for KMS encryption method');
257-259: Enhance error message for missing cypherProviderSimilar to the previous suggestion, make the error message more specific about the KMS context.
- throw new Error('No cypher provider given'); + throw new Error('cypherProvider is required for KMS encryption method');
80-85: Consider extracting cypherProvider check to a type guardThe duck typing check for cypherProvider is duplicated. While the major refactoring is planned for later, consider extracting this check into a type guard function for better maintainability.
