Class AESLean

java.lang.Object

com.coderslagoon.crypto.estreamj.ciphers.aes.AES

com.coderslagoon.crypto.estreamj.ciphers.aes.AESLean

public class AESLean
extends AES

memory efficient AES implementation; based on the work of Brian Gladman's optimizations and C code and the Bouncy Castle translation to Java; the class files' size went down to 2/3 of the original size (even after splitting of the shared base class); it is still faster since some unnecessary [>> &] operations have been taken out and got replaced with [>>>]
