Package com.coderslagoon.crypto.estreamj.ciphers.aes

Class AES

java.lang.Object
com.coderslagoon.crypto.estreamj.ciphers.aes.AES
Direct Known Subclasses:
AESLean, AESMean
public abstract class AES extends Object
AES base class, used by both the lean(=small) and the mean(=fast) class; based on the work of Brian Gladman's optimizations and C code, and the Bouncy Castle translation to Java
