Python and Ruby have similar mechanisms for calling code written in C.
M2Crypto uses SWIG to generate the wrapper code to use openssl.
SWIG can generate wrapper code for Ruby as well as Python.

The Python code being tested is the wrapper code that makes
openssl functions callable from Python, all the
crypto work is done inside libssl.so and libcrypto.so from openssl.org.

    Rajinder> Would know have an idea how M2Crypto is coded, thanks!

It is coded in much the same way as any typical Ruby Extension Module;
a google search for "swig ruby" will turn up many similiar examples.
