Are there any well-written crypto libraries, in any language?  Having spent
a frightful amount of time trudging through openssl lately as well as a
couple of Java crypto libs (Cryptix and Bouncy Castle) I've begun thinking
that the intersection between the set of people who write non-toy crypto
libraries and the set of people who write tight, clean, well-structured code
may be empty.

LOL! (literally; made my colleagues look over to see what was funny, and
when I shared, they LOL'ed too).

Another possible meaning is "consider this to be opportunistic security that
might help but might not, so don't do anything important with it."  Well,
unless you really have to and then you're back to worry in your heart.

Sorry for the content-free response.  My opinion is that dropping Python 2.4
support is fine, but I don't know much about the world of Python
