Member Function Documentation

void ElGamalDecryptor::DEREncode ( BufferedTransformation & bt ) const

Reimplemented from ElGamalEncryptor. Definition at line 124 of file elgamal.cpp.

unsigned int ElGamalDecryptor::Decrypt ( const byte * cipherText, byte * plainText ) [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 from PK_FixedLengthDecryptor. Definition at line 134 of file elgamal.cpp.
