Types

type Cryptographer

type Cryptographer interface {
	// NewSalt generates a new random salt value, of 128 bytes in size
	NewSalt() [128]byte
	// New256Key generates a new random key value, of 256 bytes in size
	New256Key() [256]byte
	// New32Key generates a new random key value, of 256 bytes in size
	New32Key() [32]byte
	// NewCipher generates a new AES cipher based on the input key
	NewCipher(key []byte) EncryptDecrypter
	// Random reads random bytes into the input byte slice
	Random(buffer []byte)
}

Cryptographer describes the set of cryptographic actions required by the app

type EncryptDecrypter

type EncryptDecrypter interface {
	// Encrypt will encrypt the input bytes `v` with the EncryptDecrypter key,
	// returning the ciphertext of `v` as a byte slice, and an error
	Encrypt(v []byte) ([]byte, error)

	// Decrypt will decipher the input bytes `v` with the EncryptDecrypter key,
	// returning the plaintext of `v` as a byte slice, and an error
	Decrypt(v []byte) ([]byte, error)
}

EncrypterDecrypter is a general purpose encryption interface that supports an Encrypt and a Decrypt method

func NewCipher

func NewCipher(key []byte) EncryptDecrypter

NewCipher generates a new AES cipher based on the input key
