Types

type BlockCrypt

type BlockCrypt int32

BlockCrypt sets the type of block crypto to use.

const (
	// BlockCrypt_UNKNOWN defaults to BlockCrypt_AES256
	BlockCrypt_BlockCrypt_UNKNOWN BlockCrypt = 0
	// BlockCrypt_NONE is unencrypted.
	BlockCrypt_BlockCrypt_NONE BlockCrypt = 1
	// BlockCrypt_AES256 is AES 256-bit block encryption.
	BlockCrypt_BlockCrypt_AES256 BlockCrypt = 2
	// BlockCrypt_AES128 is AES 128-bit block encryption.
	BlockCrypt_BlockCrypt_AES128 BlockCrypt = 3
	// BlockCrypt_AES192 is AES 192-bit block encryption.
	BlockCrypt_BlockCrypt_AES192 BlockCrypt = 4
	// BlockCrypt_SM4_16 is SM4 16-bit block encryption.
	BlockCrypt_BlockCrypt_SM4_16 BlockCrypt = 5
	// BlockCrypt_XOR is simple XOR block encryption.
	BlockCrypt_BlockCrypt_XOR BlockCrypt = 6
	// BlockCrypt_3DES is 3des 24-bit block encryption.
	BlockCrypt_BlockCrypt_3DES BlockCrypt = 7
	// BlockCrypt_SALSA20 is salsa20 32-bit block encryption.
	BlockCrypt_BlockCrypt_SALSA20 BlockCrypt = 8

func (BlockCrypt) EnumDescriptor

func (BlockCrypt) EnumDescriptor() ([]byte, []int)

func (BlockCrypt) String

func (x BlockCrypt) String() string

type Crypt

type Crypt interface {
	// Encrypt encrypts the whole block in src into dst.
	// Dst and src may point at the same memory.
	Encrypt(dst, src []byte)

	// Decrypt decrypts the whole block in src into dst.
	// Dst and src may point at the same memory.
	Decrypt(dst, src []byte)
}

Crypt defines encryption/decryption methods for a given byte slice. Notes on implementing: the data to be encrypted contains a builtin nonce at the first 16 bytes

func BuildBlockCrypt

func BuildBlockCrypt(crypt BlockCrypt, pass []byte) (Crypt, error)

BuildBlockCrypt builds block crypt from known types.
