Public Member Functions | |
virtual void | Encrypt (RandomNumberGenerator &rng, const byte *plaintext, unsigned int plaintextLength, byte *ciphertext, const NameValuePairs ¶meters=g_nullNameValuePairs) const =0 |
encrypt a byte string | |
virtual BufferedTransformation * | CreateEncryptionFilter (RandomNumberGenerator &rng, BufferedTransformation *attachment=NULL, const NameValuePairs ¶meters=g_nullNameValuePairs) const |
create a new encryption 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 | |
virtual bool | ParameterSupported (const char *name) const =0 |
this object supports the use of the parameter with the given name | |
virtual unsigned int | FixedCiphertextLength () const |
return fixed ciphertext length, if one exists, otherwise return 0 | |
virtual unsigned int | FixedMaxPlaintextLength () const |
return maximum plaintext length given the fixed ciphertext length, if one exists, otherwise return 0 | |
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 PublicKey & | AccessPublicKey ()=0 |
virtual const PublicKey & | GetPublicKey () 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 | |
Classes | |
class | InvalidPlaintextLength |
