Introduction to Python Cryptography
Overview
Python is an Object Oriented rapid development language deployed in many scenarios in the modern world.
This Introduction to Python Cryptography course is designed to give delegates the knowledge to develop/maintain Python based Cryptography scripts using the current version (V3) of Python.
There are many similarities between Python V2 and Python V3 so the skills gained on this course will allow the delegate to develop their own skills further using Python V2 or V3 to support the development and maintenance of their cryptographic requirements.
Prerequisites
Good understanding of Python Programming to the level covered on the Python Programming course.
Objectives
Knowledge of Python to write, maintain and understand Python cryptography elements.
