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

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

Implements PK_Encryptor.

virtual BufferedTransformation* PK_Encryptor::CreateEncryptionFilter ( RandomNumberGenerator rng,
BufferedTransformation attachment = NULL,
const NameValuePairs parameters = g_nullNameValuePairs 
) 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.
