RE: To Meet or Not

I concur that there is an error in the document.  My guess is that it was a
cut and paste error as my code produces the correct values, but I tended to
cut the entire blob in and then broke it apart.  Russ and I will get an
errata posted on this issue.

I just reran my test code from the development of this RFC, 
and you are correct.

I do not remember if we used my code or Jim's code to 
generate the test vector data for the RFC, but the PAD value 
is incorrect in the RFC.

Hello,

there seems to be a typo in the HMACwith3DESwrap test vector 
(chapter 
3.4) of RFC 3537. The PAD value is given as 38be62; but should be 
be62fe (see LKEYPADICV)?
