"""
demo_dynamic.py v1
This program demonstrates Python's use of the dynamic
language support additions to LTC, namely access to LTC
constants, struct and union sizes, and the binding of a
math package to LTC. Also provided are simple code
fragments to illustrate how one might write a Python
wrapper for LTC and how an app might call the wrapper.
This or a similar model should work for Ruby and other
dynamic languages.
This instance uses Python's ctypes and requires a single
.dylib linking together LTC and a math library. Building
a single .dylib is needed because LTC wants a fairly tight
relationship between itself and the mathlib. (ctypes can
load multiple .dylibs, but it does not support this level
of tight coupling between otherwise independent libraries.)
My .dylib was created on OSX with the following steps:
1- compile LTC to a .a static lib:
CFLAGS="-DLTM_DESC -DUSE_LTM" make
2- link LTC and LTM into a single .dylib:
ar2dylib_with tomcrypt tommath
where ar2dylib_with is a shell script that combines
the LTC .a with the LTM .dylib
Reminder: you don't need to bind in a math library unless
you are going to use LTC functions that depend
on a mathlib. For example, public key crypto
needs a mathlib; hashing and symmetric encryption
do not.
This code was written for Python 2.7.
