Encryption, decryption, key derivation etc.

Ok so, I think I should go back and finish that course on cryptography first....

Ok so I figure I use AES-GCM. Nonce storage is a bit tricky, but I think I have a solution, which is to store the document versions nonce at the beginning of the file, like as a header.

the document versions nonce

To clarify, I mean that since documents are encrypted with one key (that shouldn't change, at least not often), and versioning is enabled in the s3 bucket, I need to be using a nonce for each version of the document.
