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 | additional configuration options |
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.
