comment Security analysis of this one time password based scheme for copy protection
Failure to authenticate message properly usually leads to some kind of attack. This design is vulnerable to denial of service attacks of various kinds. Even the dumbest of these would cripple your user-base.

comment Is it bad design to reuse an AES key?
It's a mighty bold claim to suggest integrity checking is not an issue.Very often it turns out to be a very serious issue. The system may well be open to all sorts of chosen cipher-text attacks.

comment RFC 3526 - What does pi mean?
I assumed it had some special meaning in this context but you're telling me it's just a "nothing up my sleeve number?" Man, I feel dumb now.
