Constructor & Destructor Documentation

ecb_t()

crypto::cipher::ecb_t::ecb_t	(	const aes_t &	key,
		bool	padding = true )

Construct an AES-ECB cipher helper with key material.

Parameters

key	AES key material used to initialize the cipher.
padding	Whether the cipher should use block padding.

Member Function Documentation

decrypt()

int crypto::cipher::ecb_t::decrypt	(	const std::string_view &	cipher,
		std::vector< std::uint8_t > &	plaintext )

Decrypt ciphertext into the supplied plaintext buffer.

Parameters

cipher	Ciphertext bytes to decrypt or output buffer for encryption.
plaintext	Plaintext bytes to encrypt.

Returns

Number of bytes written, signature bytes, or an error status depending on the overload.

encrypt()

int crypto::cipher::ecb_t::encrypt	(	const std::string_view &	plaintext,
		std::vector< std::uint8_t > &	cipher )

Encrypt plaintext into the supplied ciphertext buffer.

Parameters

plaintext	Plaintext bytes to encrypt.
cipher	Ciphertext bytes to decrypt or output buffer for encryption.

Returns

Number of bytes written, signature bytes, or an error status depending on the overload.

operator=()

ecb_t & crypto::cipher::ecb_t::operator= ( ecb_t && )

defaultnoexcept

Assign state from another instance while preserving ownership semantics.

Returns

Reference or value produced by the operator.
