S3 Package: Server-side Encryption

[jonsharratt]

What did you implement:

By default add AES256 encryption for data sitting in S3.

Use Server-Side Encryption with Amazon S3-Managed Keys (SSE-S3)
Each object is encrypted with a unique key employing strong multi-factor encryption. As an additional safeguard, it encrypts the key itself with a master key that it regularly rotates. Amazon S3 server-side encryption uses one of the strongest block ciphers available, 256-bit Advanced Encryption Standard (AES-256), to encrypt your data.

How did you implement it:

• Added bucket policy to enforce encrypted data to ensure all objects are published encrypted.

How can we verify it:

• npm t
• Deploy registry and attempt publish and dist-tags operations

Todos:

• Write tests
  Write documentation
• Fix linting errors
• Tag ready for review or wip

Is this a breaking change?: YES
