Functions

func Decrypt

func Decrypt(ciphertext []byte, 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 EncodeECDSAKey

func EncodeECDSAKey(w io.Writer, key *ecdsa.PrivateKey) error

see: https://github.com/golang/crypto/blob/5c72a883971a4325f8c62bf07b6d38c20ea47a6a/acme/autocert/autocert.go#L547

func Encrypt

func Encrypt(plaintext []byte, 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. source: https://github.com/gtank/cryptopasta/blob/master/encrypt.go (bc3a108a5776376aa811eea34b93383837994340)
