Functions

func DecryptSymmetric

func DecryptSymmetric(ciphertext, secret []byte) (plaintext []byte, err error)

secret must be 32 bytes long. Use something like Sha256(Bcrypt(passphrase)) The ciphertext is (secretbox.Overhead + 24) bytes longer than the plaintext.

func EncryptSymmetric

func EncryptSymmetric(plaintext, secret []byte) (ciphertext []byte)

secret must be 32 bytes long. Use something like Sha256(Bcrypt(passphrase)) The ciphertext is (secretbox.Overhead + 24) bytes longer than the plaintext.
