| 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 |

| 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 | |
