Member Function Documentation

unsigned int PK_Decryptor::Decrypt ( const byte * cipherText, unsigned int cipherTextLength, byte * plainText ) [pure 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 in BlumGoldwasserPrivateKey, PK_FixedLengthDecryptor, and ECDecryptor.
