What's missing from python?

[John Burton]

One of the reasons I like python so much is that the standard 
installation comes with a whole lot of libraries to do lots of useful 
things but there seem to be a few things missing from the standard 
library which would be useful in many projects:

Encryption - AES and 3DES. Possibly RSA and Certificate processing.
DNS - Something better than gethostbyaddr for looking up other record types.
Database - Something suitable for small projects / prototypes like 
pysqlite or something in pure python even.
SSL/TLS - Some useful support...

A lot of projects seem to need some of those. It's easy enough to 
install extras to do those thing but they are all things where it would 
be nice to have something in the standard library that you could rely on 
being there.

Is there any reason why those things are not already in the standard 
library?
