Functions

func AESDecrypt

func AESDecrypt(ciphertext, key []byte) ([]byte, error)

AESDecrypt decrypts a payload encrypted using AES-CBC and PKCS#7 padding. The decryption algorithm makes three assumptions: 1. ciphertext is aligned to the standard AES block size 2. ciphertext is padded using PKCS#7 3. the IV is prepended to ciphertext This function is DEPRECATED. Use Decrypt() instead.

func AESEncrypt

func AESEncrypt(plaintext, key []byte) ([]byte, error)

AESEncrypt encrypts a payload using AES-CBC and PKCS#7 padding. The returned ciphertext has three notable properties: 1. ciphertext is aligned to the standard AES block size 2. ciphertext is padded using PKCS#7 3. IV is prepended to the ciphertext This function is DEPRECATED. Use Encrypt() instead.

func Decrypt

func Decrypt(ciphertext, key []byte) (plaintext []byte, err error)

Decrypt decrypts data using 256-bit AES-GCM. This both hides the content of the data and provides a check that it hasn't been altered. Expects input form nonce|ciphertext|tag where '|' indicates concatenation.

func Encrypt

func Encrypt(plaintext, key []byte) (ciphertext []byte, err error)

Encrypt encrypts data using 256-bit AES-GCM. This both hides the content of the data and provides a check that it hasn't been altered. Output takes the form nonce|ciphertext|tag where '|' indicates concatenation.

func RandBytes

func RandBytes(n int) ([]byte, error)
