Public Types | |
typedef T | Element |
Public Member Functions | |
DecodingResult | Decrypt (RandomNumberGenerator &rng, const byte *ciphertext, unsigned int ciphertextLength, byte *plaintext, const NameValuePairs ¶meters=g_nullNameValuePairs) const |
decrypt a byte string, and return the length of plaintext | |
unsigned int | MaxPlaintextLength (unsigned int ciphertextLength) const |
maximum length of plaintext for a given ciphertext length | |
unsigned int | CiphertextLength (unsigned int plaintextLength) const |
calculate length of ciphertext given length of plaintext | |
bool | ParameterSupported (const char *name) const |
this object supports the use of the parameter with the given name | |
virtual BufferedTransformation * | CreateDecryptionFilter (RandomNumberGenerator &rng, BufferedTransformation *attachment=NULL, const NameValuePairs ¶meters=g_nullNameValuePairs) const |
create a new decryption filter | |
DecodingResult | FixedLengthDecrypt (RandomNumberGenerator &rng, const byte *ciphertext, byte *plaintext, const NameValuePairs ¶meters=g_nullNameValuePairs) const |
decrypt a fixed size ciphertext | |
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 PrivateKey & | AccessPrivateKey ()=0 |
virtual const PrivateKey & | GetPrivateKey () const |
void | BERDecode (BufferedTransformation &bt) |
