Hello, JCE implements the AESWrap cipher, but it's does not offer the KWP mode of NIST 800-38F. KW and KWP use the same wrapping algorithm W which is also used by AESWrap, however do to different initialisation vectors the existing implementation can not be used to implement the padded wrapping.
Is it possible to offer KWP as a special padding mode for AESWrap or have the W mode be it's own block mode so you can implement the padding externally? Gruss Bernd -- http://bernd.eckenfels.net
