abstract class EME;
Encoding Method for Encryption
abstract const size_t maximumInputSize(size_t keybits);
- Parameters
size_t keybits the size of the key in bits - Returns
- upper bound of input in bytes
Return the maximum input size in bytes we can support
final const SecureVector!ubyte encode(const(ubyte)* msg, size_t msg_len, size_t key_bits, RandomNumberGenerator rng);
- Parameters
const(ubyte)* msg the plaintext size_t msg_len length of plaintext in bytes size_t key_bits length of the key in bits RandomNumberGenerator rng a random number generator - Returns
- encoded plaintext
Encode an input
final const SecureVector!ubyte encode(ref const SecureVector!ubyte msg, size_t key_bits, RandomNumberGenerator rng);
- Parameters
SecureVector!ubyte msg the plaintext size_t key_bits length of the key in bits RandomNumberGenerator rng a random number generator - Returns
- encoded plaintext
Encode an input
final const SecureVector!ubyte decode(const(ubyte)* msg, size_t msg_len, size_t key_bits);
- Parameters
const(ubyte)* msg the encoded plaintext size_t msg_len length of encoded plaintext in bytes size_t key_bits length of the key in bits - Returns
- plaintext
Decode an input
final const SecureVector!ubyte decode(ref const SecureVector!ubyte msg, size_t key_bits);
- Parameters
SecureVector!ubyte msg the encoded plaintext size_t key_bits length of the key in bits - Returns
- plaintext
Decode an input
