| HC128Engine | | public class HC128Engine implements StreamCipher(Code) | | HC-128 is a software-efficient stream cipher created by Hongjun Wu. It
generates keystream from a 128-bit secret key and a 128-bit initialization
vector.

It is a third phase candidate in the eStream contest, and is patent-free.
No attacks are known as of today (April 2007). See

| init | | public void init(boolean forEncryption, CipherParameters params) throws IllegalArgumentException(Code) | | Initialise a HC-128 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 128 bit long). |
