Hi all,

I'd like to announce TLS Lite v0.2.0 (the first public release, despite 

TLS Lite is a pure-python, public domain SSL/TLS library.  It has minimal 
support for X.509 certificates, but focuses on up-and-coming authentication 
methods like SRP [1], shared-keys [2], and cryptoIDs [3].

These methods are easier to use than PKI.  They're also barely out of the 
oven - the first two are Internet-Drafts, and the last is something I made 
up.  It's fun stuff to mess with, but keep in mind that the drafts may 
change, and the code's alpha quality..

Other highlights:
  - SSL v3 and TLS v1 support
  - Pure python
    - with AES, throughput ~25 KB/sec, on a P4 1.7 Ghz
    - with RC4, throughput ~250 KB/sec
  - Can use cryptlib [4] or OpenSSL/M2crypto [5] for faster ciphers & math:
    - throughput ~6 MB/sec
  - Integrates with httplib and SocketServer framework
