<div dir="ltr">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.</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">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?</div>
