Member Function Documentation

unsigned int PK_FixedLengthDecryptor::Decrypt ( const byte * cipherText, unsigned int cipherTextLength, byte * plainText ) [virtual]

decrypt a byte string, and return the length of plaintext. Precondition: size of plainText == MaxPlainTextLength(cipherTextLength) bytes. The function returns the actual length of the plaintext, or 0 if decryption fails. Reimplemented from PK_Decryptor. Definition at line 463 of file cryptlib.cpp.

unsigned int PK_FixedLengthDecryptor::Decrypt ( const byte * cipherText, byte * plainText ) [pure virtual]

decrypt a byte string, and return the length of plaintext. Preconditions: \begin{itemize} \item length of cipherText == CipherTextLength() \item size of plainText == MaxPlainTextLength() \end{itemize} The function returns the actual length of the plaintext, or 0 if decryption fails. Reimplemented in ElGamalDecryptor, LUCELG_Decryptor, and DecryptorTemplate. Referenced by Decrypt().
