Overview

Package crypto provides AES-256-CTR encryption and HMAC-SHA1 authentication compatible with git-crypt.

• func Decrypt(data []byte, key *keyfile.Key) ([]byte, error)
• func Encrypt(plaintext []byte, key *keyfile.Key) ([]byte, error)

Variables

var ErrHMACMismatch = errors.New("crypto: HMAC verification failed")

ErrHMACMismatch indicates that the HMAC verification failed during decryption.

Functions

func Decrypt

func Decrypt(data []byte, key *keyfile.Key) ([]byte, error)

Decrypt decrypts a git-crypt encrypted file using AES-256-CTR and verifies the HMAC-SHA1 nonce.

func Encrypt

func Encrypt(plaintext []byte, key *keyfile.Key) ([]byte, error)

Encrypt encrypts plaintext using AES-256-CTR with an HMAC-SHA1 derived nonce, producing output compatible with git-crypt.
