67-69: Fix method name to correctly implement Angular lifecycle hookThe method
AfterViewInit()should be renamed tongAfterViewInit()to properly implement the AngularAfterViewInitlifecycle hook. Without the correct method name, the framework will not call this hook, and the focus action will not occur as intended.Apply this diff to correct the method name:
-public AfterViewInit(): void { +ngAfterViewInit(): void { this.elementRef.nativeElement.focus(); }

43-46: Avoid hardcoding cryptographic keys and saltsStoring cryptographic keys and salts directly in the source code is insecure and can lead to vulnerabilities if the codebase is compromised. Consider storing
SALTandKey_IVin environment variables or a secure key management system to enhance security.
Line range hint
49-51: Increase iteration count for stronger key derivationThe current iteration count for PBKDF2 is set to
1989, which may not be sufficient for secure key derivation. It is recommended to use a higher iteration count (e.g.,100000or more) to enhance resistance against brute-force attacks.Consider updating the iteration count:
-this._iterationCount = 1989; +this._iterationCount = 100000;

112-195: Refactor nested subscriptions to use RxJS operatorsThe current implementation contains multiple nested
subscribecalls, which can lead to callback nesting and make the code harder to read and maintain. Consider refactoring the code to use RxJS operators likeswitchMap,mergeMap, orconcatMapto flatten the observable chains and improve readability.Here's an example of how you might refactor the
loginmethod usingswitchMap:login() { const encryptPassword = this.encrypt( this.Key_IV, this.loginForm.controls.password.value, ); if ( this.loginForm.controls.userName.value && this.loginForm.controls.password.value ) { const username = this.loginForm.controls.userName.value.trim(); this.authService.login(username, encryptPassword, false).pipe( switchMap((res: any) => { if (res.statusCode === 200) { // Handle successful login if (res?.data?.previlegeObj[0]) { localStorage.setItem('loginDataResponse', JSON.stringify(res.data)); this.getServicesAuthdetails(res.data); // Additional logic... return of(res); } else { this.confirmationService.alert( 'Seems you are logged in from somewhere else, Logout from there & try back in.', 'error', ); return EMPTY; } } else if (res.statusCode === 5002) { if ( res.errorMessage === 'You are already logged in,please confirm to logout from other device and login again' ) { return this.confirmationService.confirm('info', res.errorMessage).pipe( switchMap((confirmResponse) => { if (confirmResponse) { return this.authService.userLogoutPreviousSession(username).pipe( switchMap((logoutRes: any) => { if (logoutRes.statusCode === 200) { return this.authService.login(username, encryptPassword, true).pipe( tap((loginRes: any) => { if (loginRes.statusCode === 200) { // Handle successful login after logout if (loginRes?.data?.previlegeObj[0]) { localStorage.setItem( 'loginDataResponse', JSON.stringify(loginRes.data), ); this.getServicesAuthdetails(loginRes.data); } else { this.confirmationService.alert( 'Seems you are logged in from somewhere else, Logout from there & try back in.', 'error', ); } } else { this.confirmationService.alert( loginRes.errorMessage, 'error', ); } }) ); } else { this.confirmationService.alert( logoutRes.errorMessage, 'error', ); return EMPTY; } }) ); } else { sessionStorage.clear(); this.router.navigate(['/login']); this.confirmationService.alert(res.errorMessage, 'error'); return EMPTY; } }) ); } else { this.confirmationService.alert(res.errorMessage, 'error'); return EMPTY; } } else { this.confirmationService.alert(res.errorMessage, 'error'); return EMPTY; } }) ).subscribe( () => {}, (err) => { this.confirmationService.alert(err, 'error'); } ); } }This refactoring uses
switchMapto handle the observable streams, reducing nested subscriptions and improving code maintainability.

162-169: Avoid storing sensitive data in localStorage and sessionStorageStoring sensitive information like authentication keys, user IDs, and user names in
localStorageorsessionStoragecan expose them to XSS attacks, as they are accessible through JavaScript. Consider using secure, HTTP-only cookies or other secure storage mechanisms to store such sensitive data.
Line range hint
201-208: Simplify show/hide password functionalityThe
showPWDandhidePWDmethods can be simplified by using a boolean flag to toggle the password visibility. This reduces the number of methods and simplifies the template binding.Consider refactoring as follows:
passwordVisible = false; togglePasswordVisibility() { this.passwordVisible = !this.passwordVisible; }In your template, you can bind the
typeattribute:<input [type]="passwordVisible ? 'text' : 'password'" ... /> <button (click)="togglePasswordVisibility()">Show/Hide Password</button>

91-98: Review client-side encryption of passwordsEncrypting passwords on the client side before sending them to the server can introduce security concerns and may not provide the intended security benefits. It's generally more secure to send passwords over HTTPS and handle encryption and hashing on the server side. Please ensure this approach aligns with security best practices.
Run the following script to check for similar patterns in the codebase:
✅ Verification successful
Client-side password encryption not detected in the codebase. No action needed.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Search for client-side password encryption implementations. # Test: Find occurrences where passwords are encrypted on the client side. # Expect: Verify if similar patterns exist elsewhere that may need review. rg --type typescript "encrypt\(.+password.+\)"Length of output: 83
