ashu.dagar


Description:

Mcrypt library is open source library https://github.com/aer0s/python-mcrypt. It is used to ensure interoperability between encryption/decryption in PHP/CodeIgniter framework and backend code written in Python 2.7. Lots of People who have a mix of PHP & Python in their system would be using this library. Mcrypt is primarily used in Php.

The current status of the lib is in an abandoned state, and no plan from the original author to port it to Python 3. Considering the dependency of this lib in our platform and effort calculation, we decided on porting this to python 3 and contribute to open source. This effort led us to learn of CPython and the joy of giving back to the open-source community.

This talk will provide the basic guidelines for the CPython extension conversion. This talk will provide a detailed example for the library conversion which will help you mysteries behind Bytes, Unicode, Strings, base64, etc.

Prerequisites:

Basic knowledge of Python and C Language.

This discussion will help in understanding for all python professionals who currently in-migration from Pyhton2 to Python3 with the understanding of CPython.

Content URLs:
