throws CryptoTokenException
- Encrypts a block of the given plaintext into a block of ciphertext.
- Parameters:
plaintext - A byte array containing the input that is to be encrypted.plaintextOffset - The starting offset, or initial byte position, of
the data within the input array.ciphertext - A byte array to hold the ciphertext output from the method.ciphertextOffset - The starting offset, or initial byte position, of
the data within the output array.
- Throws:
CryptoTokenException - Thrown when an problem occurs with the
crypto token or the crypto token is invalid.- Category:
