inlinevirtual |
Encrypt a byte string.
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 |
CiphertextLength(plaintextLength) != 0
ensures the plaintext isn't too large COUNTOF(ciphertext) == CiphertextLength(plaintextLength)
ensures the output byte buffer is large enough. Implements PK_Encryptor.
