Note that Pat Knight has a UK-based project to SWIG SSLeay;
could you work using that as a base? http://www.ktgroup.co.uk/~pat/

I've looked at that code before I started off into mxCrypto. Pat's
approach uses pointers in the internal OpenSSL's data structure
as basis for doing the wrapping. Unfortunately, those pointers
seem to not work properly anymore in more recent versions of OpenSSL.

Also, he swigged the BIO and SSL parts in OpenSSL, mxCrypto takes
care of most of the crypto routines. X.509 and ASN.1 are not
handled in Pat's version.

Thanks for the tip anyway :-)

Well, the NCSA folks did something similar in their WWW server (they
included bindings to some crypto-lib for authentication) and
were called back by the NSA... but maybe the situation is different
now.

That's debatable. The SWIG bindings contain no crypto code in their own right.
It is merely glue to crypto code. I wouldn't be able to release statically
prebuilt libraries, but why would I want to anyway? Our lawyers keep waffling
on this, which is why I haven't released it already. I'm really pleased with
it, and would love give something back to the Python community. <SIGH> How
long before we Americans are reduced to doing Crypto with a deck of cards? (See
Bruce Schneier's Solitaire).
