void TF_EncryptorBase::Encrypt ( RandomNumberGenerator rng,
const byte *  plaintext,
size_t  plaintextLength,
byte *  ciphertext,
const NameValuePairs parameters = g_nullNameValuePairs 
) const [virtual]

Encrypt a byte string.

Parameters:
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 additional configuration options
Precondition:
CiphertextLength(plaintextLength) != 0 ensures the plaintext isn't too large
COUNTOF(ciphertext) == CiphertextLength(plaintextLength) ensures the output byte buffer is large enough.

) const [virtual, inherited]

Create a new encryption filter.

Note:
The caller is responsible for deleting the returned pointer.
Encoding parameters should be passed in the "EP" channel.

virtual std::string Algorithm::AlgorithmName (  )  const [inline, virtual, inherited]

Provides the name of this algorithm.

Returns:
the standard algorithm name

The standard algorithm name can be a name like AES or AES/GCM. Some algorithms do not have standard names yet. For example, there is no standard algorithm name for Shoup's ECIES.

Note:
AlgorithmName is not universally implemented yet

Reimplemented in Adler32, CCM_Base, CRC32, ClassNullRNG, AuthenticatedSymmetricCipher, DH_Domain< GROUP_PARAMETERS, COFACTOR_OPTION >, EAX_Base, StreamTransformationFilter, HashFilter, HashVerificationFilter, AuthenticatedDecryptionFilter, SignerFilter, SignatureVerificationFilter, GCM_Base, HMAC< T >, RDRAND, RDSEED, SHA3, BitBucket, and VMAC_Base.
