update

public byte[] update(byte[] bytes)
              throws IllegalStateException,
TokenException

Description copied from class: Cipher

Updates the encryption context with additional input.

Specified by:

update in class Cipher

Parameters:

bytes - Bytes of plaintext (if encrypting) or ciphertext (if decrypting).

Returns:

Bytes of ciphertext (if encrypting) or plaintext (if decrypting).

Throws:

IllegalStateException

TokenException

Parameters:

bytes - Bytes of plaintext (if encrypting) or ciphertext (if decrypting).

offset - The index in bytes at which to begin reading.

length - The number of bytes from bytes to read.

Returns:

Bytes of ciphertext (if encrypting) or plaintext (if decrypting).
