The key wrap algorithms defined in [3DES-WRAP] and [AES-WRAP] cover the of
wrapping a Triple-DES key with another Triple-DES key and wrapping an AES key
with another AES key, respectively. This document specifies two similar
mechanisms. One specifies the mechanism for wrapping an HMAC key with a
Triple-DES key, and the other specifies the mechanism for wrapping an HMAC key
with an AES key.
Given that RFC 3211 specifies a universal algorithm for wrapping any key in any
other key, is there any need to create special-case x-in-y wrap RFCs of this
kind? This draft seems entirely superfluous, since a standards-track RFC
containing an algorithm which does what's in the draft already exists.
