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

Encrypt a byte string.

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
CiphertextLength(plaintextLength) != 0 ensures the plaintext isn't too large
COUNTOF(ciphertext) == CiphertextLength(plaintextLength) ensures the output byte buffer is large enough.

BufferedTransformation * PK_Encryptor::CreateEncryptionFilter ( RandomNumberGenerator rng,

const NameValuePairs parameters = g_nullNameValuePairs 
) const

Create a new encryption filter.

The caller is responsible for deleting the returned pointer.
Encoding parameters should be passed in the "EP" channel.
