iocrypter is a Go package that implements AES-256-CTR encryption with SHA-512 HMAC authentication
as a io.Reader interface. It allows the en- and decryption with authentication of arbitrary data
from any given io.Reader.
It derives a secure key for the AES-256 encryption using Argon2ID. Encryption parameters like the Argon2 settings, the salt and the IV are stored at the start of the ciphertext, making it convenient for byte stream encryption.
The cmd/ directory holds two example implementations for tools that will read a file from disk and then en- or decrypt it accordingly.
The scs directory holds a package that provides an implementation of the Codec interface for Alex Edwards' SCS: HTTP Session Management. It enables the use of iocrypter to encrypt and authenticate session data before storing them in any supported SCS session storage.
