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
rnga RandomNumberGenerator derived class
plaintextthe plaintext byte buffer
plaintextLengththe size of the plaintext byte buffer
ciphertexta byte buffer to hold the encrypted string
parametersadditional 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
virtualinherited

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
inlinevirtualinherited

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