Public Member Functions | |
virtual DecodingResult | FixedLengthDecrypt (RandomNumberGenerator &rng, const byte *cipherText, byte *plainText) const =0 |
decrypt a byte string, and return the length of plaintext | |
DecodingResult | Decrypt (RandomNumberGenerator &rng, const byte *cipherText, unsigned int cipherTextLength, byte *plainText) const |
decrypt a byte string, and return the length of plaintext | |
virtual BufferedTransformation * | CreateDecryptionFilter (RandomNumberGenerator &rng, BufferedTransformation *attachment=NULL) const |
create a new decryption filter | |
virtual unsigned int | MaxPlaintextLength (unsigned int cipherTextLength) const =0 |
maximum length of plaintext for a given ciphertext length | |

calculate length of ciphertext given length of plaintext | |
CryptoMaterial & | AccessMaterial () |
returns a reference to the crypto material used by this object | |
const CryptoMaterial & | GetMaterial () const |
returns a const reference to the crypto material used by this object | |
virtual PrivateKey & | AccessPrivateKey ()=0 |
virtual const PrivateKey & | GetPrivateKey () const |
void | BERDecode (BufferedTransformation &bt) |
