Re: single-DES phase 1

[Rukshin, David]

RedCreek Personal Ravlin has the same issue, it seems.  Didn't test the
latest version of the software, but up 3.4 had the limitation.  It's not
clearly documented, but it seems that single-DES can be used for phase 1
(although both MD5 and HMAC are supported).

Thanks,
Dave
