Cryptography is an essential part of secure but accessible communication that's critical for our everyday life and organisations use it to protect their privacy and keep their conversations and data confidential. This course provides a comprehensive introduction to the fascinating world of cryptography, covering both historical cyphers and modern-day cryptographic techniques.
In this course, you will explore the foundations of encryption, decryption, and cryptographic protocols. Through a combination of theoretical concepts, practical examples, and hands-on exercises, you will gain a solid understanding of the principles and applications of cryptography.
Join this fascinating course to explore the world of cryptography and learn how secrets have been kept in the past and the modern world.

Welcome to the first week of the course! We will start the week with an exploration of what cryptography is and what it is used for and then move on to look at some cryptographic techniques, via some ancient cryptography. Although these ancient cryptographic techniques are not very useful in modern life, they are good at demonstrating some of the concepts that are still used in modern day cryptography. Week 1 lays the foundation for Week 2, when we will turn our attention to modern cryptography.

Welcome to Week 2. In this week you will bring your knowledge about cryptography up to date in the modern day. This is where we start to look at more complex methods for more complex contemporary requirements. To start off, you will be introduced to a concept called 'public key cryptography' which is extensively used on the internet. You will then learn about hash functions and how some cryptographic techniques can be used to produce a digital signature.

When will I have access to the lectures and assignments?
To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I purchase the Certificate?
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
Is financial aid available?
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
