| HC256Engine | | public class HC256Engine implements StreamCipher(Code) | | HC-256 is a software-efficient stream cipher created by Hongjun Wu. It
generates keystream from a 256-bit secret key and a 256-bit initialization
vector.

Its brother, HC-128, is a third phase candidate in the eStream contest.
The algorithm is patent-free. No attacks are known as of today (April 2007).

| init | | public void init(boolean forEncryption, CipherParameters params) throws IllegalArgumentException(Code) | | Initialise a HC-256 cipher.
Parameters:
forEncryption - whether or not we are for encryption. Irrelevant, asencryption and decryption are the same.
Parameters:
params - the parameters required to set up the cipher.
throws:
IllegalArgumentException - if the params argument isinappropriate (ie. the key is not 256 bit long). |
