Member Function Documentation

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

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.
