org.jose4j.keys.AesKey
org.keyczar.AesKey
Wrapping class for AES keys. Currently the default is to use CBC mode. @author steveweis@gmail.com (Steve Weis) @author arkajit.dey@gmail.com (Arkajit Dey)
org.smslib.crypto.AESKey
Class representing an AES algorithm encryption key. The class is based on standard JDK AES implementation (128 bit key).
