Method Detail

encrypt

void encrypt(byte[] plaintext,
             int plaintextOffset,
             byte[] ciphertext,
             int ciphertextOffset,
             int numBlocks)
             throws CryptoTokenException

Encrypts a series of blocks of the given plaintext into a series of blocks 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.

numBlocks - The number of blocks to encrypt.

Throws:

CryptoTokenException - Thrown when an problem occurs with the crypto token or the crypto token is invalid.
