About the course

Python Programming & Cryptography Course Overview

Python is an Object Oriented rapid development language deployed in many scenarios in the modern world.

This Python Programming & Cryptography course is designed to give delegates the knowledge to develop / maintain Python scripts including cryptographic elements 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 maintenance of scripts and their cryptographic requirements.

Skills Gained

The delegate will learn to:

  • Declare variables and initialise them
  • Construct expressions with arithmetic, logical and relational operators
  • Use iterative type statements
  • Use conditional statements
  • Read/write text and binary files
  • Manipulate text using regular expression
  • Declare and use modules
  • Use and create Python Objects
  • Use built-in library functions
  • Use lists and dictionaries
  • Interact with the email system
  • Interact with Databases
  • Understand the differences in Random Number Generation Techniques
  • Create symmetric keys
  • Use the techniques used in symmetric encryption
  • Understand the differences between Symmetric and Asymmetric encryption
  • Use signatures and understand how they can be used
  • Use Hash algorithms and understand how they can be employed for security

Who will the Course Benefit?

Programmers who need to write, maintain and understand Python scripts including cryptographic based elements.

Course Objectives

Knowledge of Python to write, maintain and understand Python scripts and cryptographic elements.

Requirements

Familiarisation with programming concepts is useful, this knowledge can be obtained by attendance on the Concepts of Programming course.
