Decryption result. This represents whether the decryption of a cipheretext was performed correctly.

This is intended to eventually incorporate information about the amount of padding in a decoded ciphertext, to ensure that the correct amount of padding is stripped away. It is intended to provided a very simple kind of checksum eventually. This notion of a decoding output is inherited from the crypto++ library. It is also intended to be used in a recover and restart robust functionality if not all ciphertext is recieved over a lossy channel, so that if all information is eventually received, decoding/decryption can be performed eventually. This is intended to be returned with the output of a decryption operation.

Public Functions

inline DecryptResult(): Constructor that initializes all message lengths to 0.

inline explicit DecryptResult(size_t len)

Constructor that initializes all message lengths.

Parameters: len – the new length.

inline explicit DecryptResult(size_t len, NativeInteger scf)

Constructor that initializes all message lengths.

Parameters

len – the new length.
scf – the new scaling factor.

Public Members

bool isValid: whether the decryption was successful

usint messageLength: the length of the decrypted plaintext message
