Functions

func CTEq

func CTEq(c1, c2 CipherText) bool

CTEq checks ciphertexts' equality.

func GenerateKeys

func GenerateKeys() (EncryptionKey, DecryptionKey, error)

GenerateKeys creates a pair of keys for encryption/decryption

Types

type CipherText

type CipherText []byte

CipherText represents encrypted data.

type DecryptionKey

type DecryptionKey interface {
	// Decrypt decrypts ciphertext that was encrypted with corresponding encryption key.
	Decrypt(CipherText) ([]byte, error)
	// Encode encodes the decryption key.
	Encode() string
}

DecryptionKey is used for decrypting ciphertexts encrypted with corresponding encryption key.

func NewDecryptionKey

func NewDecryptionKey(text string) (DecryptionKey, error)

NewDecryptionKey creates a decryptionKey from its string representation

type EncryptionKey

type EncryptionKey interface {
	// Encrypt encrypts message.
	Encrypt([]byte) (CipherText, error)
	// Encode encodes the encryption key.
	Encode() string
}

EncryptionKey is used for encrypting messages.

func NewEncryptionKey

func NewEncryptionKey(text string) (EncryptionKey, error)

NewEncryptionKey creates encryptionKey from string representation

type SymmetricKey

type SymmetricKey interface {
	// Encrypt encrypts message.
	Encrypt([]byte) (CipherText, error)
	// Decrypt decrypts ciphertext that was encrypted with the key.
	Decrypt(CipherText) ([]byte, error)
}

SymmetricKey is used for both encrypting and decrypting messages.

func NewSymmetricKey

func NewSymmetricKey(key []byte) (SymmetricKey, error)

NewSymmetricKey creates a symmetric key for encryption/decryption.
