func Decrypt(token string, key []byte) (*types.SecureToken, error)

Decrypt returns the decrypted SecureToken. It's only intended to be used from debugging utilities.

New generates a token from the provided protocol message, encrypting and signing it with the provided 32-byte symmetric key.

func VerifyAndUnmarshal 

func VerifyAndUnmarshal(dst proto.Message, token string, maxAge time.Duration, key []byte) error

VerifyAndUnmarshal unmarshals a token created by NewToken into the provided protocol message. An error is returned if the token is too new, too old, cryptographically invalid, or if the type of the destination message and contained message do not match.

	Key []byte // A key with which to sign and encrypt tokens.  Must be exactly 32 bytes.
}
