Encrypt()

template<class T >

void DL_EncryptorBase< T >::Encrypt ( RandomNumberGenerator &  rng, const byte *  plaintext, size_t  plaintextLength, byte *  ciphertext, const NameValuePairs &  parameters = g_nullNameValuePairs  ) const

inlinevirtual

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	a 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.
