comment How to create a PEM file for storing an RSA key?
@poncho: Technically, this question is about implementing a standard storage format for cryptographic keys. The mention of OpenSSL is really a red herring. I think it's on topic here, if perhaps marginally. (And there's certainly some overlap with Stack Overflow here; not that there's necessarily anything wrong with that.)

comment Definition of the term “key”
Note that a key (in the sense of "thing used to open a lock") is also a key (in the sense of "essential to make something work"). Without a matching key, a lock is little more than a useless lump of metal.

comment Diffie Hellman Exponentiation Implementation Problem
Yeah, it's a dupe, but the original could really use a better answer. Of the three answers so far, one is buggy, one is (mostly) irrelevant and one takes way too long to get to the point.

comment Discrete logarithm over prime modulo: small input, large exponent, larger prime
Terminology nitpick: HMAC is a specific MAC algorithm (or, rather, a method of constructing a MAC from a cryptographic hash), of which this method is not an instance of. It's not really meaningful to ask whether something is "an HMAC", since only HMAC is an HMAC. You could ask whether this algorithm is a MAC (i.e. whether it satisfies the relevant unforgeability properties), though.
