void TF_EncryptorBase::Encrypt RandomNumberGenerator rng,
const byte *  plaintext,
unsigned int  plaintextLength,
byte *  ciphertext,
const NameValuePairs parameters = g_nullNameValuePairs
const [virtual, inherited]
 

encrypt a byte string

Precondition:
CiphertextLength(plaintextLength) != 0 (i.e., plaintext isn't too long)

size of ciphertext == CiphertextLength(plaintextLength)

Implements PK_Encryptor.

Note:
The caller is responsible for deleting the returned pointer.

Encoding parameters should be passed in the "EP" channel.
