func SymmetricEncrypt

func SymmetricEncrypt(ea Alg, plainText, key []byte) (cipherText []byte, err error)

Types

type AesGcm256

type AesGcm256 struct{}

func NewAesGcm256

func NewAesGcm256() *AesGcm256

func (*AesGcm256) Decrypt

func (a *AesGcm256) Decrypt(ciphertext []byte, key []byte, normalizeWithSha256 bool) (plaintext []byte, err error)

256-bit AES-GCM with a random nonce Reference: https://github.com/gtank/cryptopasta/blob/master/encrypt.go 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 (*AesGcm256) Encrypt

func (a *AesGcm256) Encrypt(plaintext []byte, key []byte, normalizeWithSha256 bool) (ciphertext []byte, err error)

256-bit AES-GCM with a random nonce Reference: https://github.com/gtank/cryptopasta/blob/master/encrypt.go 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.
