Public Member Functions | |
virtual DecodingResult | Decrypt (RandomNumberGenerator &rng, const byte *cipherText, unsigned int cipherTextLength, byte *plainText) const =0 |
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 | |
virtual unsigned int | CiphertextLength (unsigned int plainTextLength) const =0 |
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) |
for backwards compatibility, calls AccessMaterial().Load(bt) | |
void | DEREncode (BufferedTransformation &bt) const |
for backwards compatibility, calls GetMaterial().Save(bt) | |
virtual std::string | AlgorithmName () const |
returns name of this algorithm, not universally implemented yet | |
virtual Clonable * | Clone () const |
this is not implemented by most classes yet |
