Public Member Functions inherited from PK_CryptoSystem | |
virtual size_t | MaxPlaintextLength (size_t ciphertextLength) const =0 |
Provides the maximum length of plaintext for a given ciphertext length. | |
virtual size_t | CiphertextLength (size_t plaintextLength) const =0 |
Calculate the length of ciphertext given length of plaintext. | |
virtual bool | ParameterSupported (const char *name) const =0 |
Determines whether this object supports the use of a named parameter. | |
virtual size_t | FixedCiphertextLength () const |
Provides the fixed ciphertext length, if one exists. | |
virtual size_t | FixedMaxPlaintextLength () const |
Provides the maximum plaintext length given a fixed ciphertext length. | |
Public Member Functions inherited from PublicKeyAlgorithm | |
CryptoMaterial & | AccessMaterial () |
Retrieves a reference to a Public Key. | |
const CryptoMaterial & | GetMaterial () const |
Retrieves a reference to a Public Key. | |
virtual PublicKey & | AccessPublicKey ()=0 |
Retrieves a reference to a Public Key. | |
virtual const PublicKey & | GetPublicKey () const |
Retrieves a reference to a Public Key. | |
Public Member Functions inherited from Algorithm | |
Algorithm (bool checkSelfTestStatus=true) | |
Interface for all crypto algorithms. | |
virtual std::string | AlgorithmName () const |
Provides the name of this algorithm. | |

virtual |
Create a new encryption filter.
rng | a RandomNumberGenerator derived class |
attachment | an attached transformation |
parameters | a set of NameValuePairs to initialize this object |
attachment
can be NULL
. The caller is responsible for deleting the returned pointer. Encoding parameters should be passed in the "EP" channel.

pure virtual |
Encrypt a byte string.
rng | a RandomNumberGenerator derived class |
plaintext | the plaintext byte buffer |
plaintextLength | the size of the plaintext byte buffer |
ciphertext | a byte buffer to hold the encrypted string |
parameters | a set of NameValuePairs to initialize this object |
CiphertextLength(plaintextLength) != 0
ensures the plaintext isn't too large COUNTOF(ciphertext) == CiphertextLength(plaintextLength)
ensures the output byte buffer is large enough. Implemented in DL_EncryptorBase< T >.
