Member Function Documentation

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
parametersa set of NameValuePairs to initialize this object
Precondition
CiphertextLength(plaintextLength) != 0 ensures the plaintext isn't too large
COUNTOF(ciphertext) == CiphertextLength(plaintextLength) ensures the output byte buffer is large enough.
