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. This course is one of many, offered by Click Start, a UK training programme designed to help young people develop digital skills. Click Start offers a limited number of scholarships giving free access to young people in the UK.

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.

Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. 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.
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. If you only want to read and view the course content, you can audit the course for free.
You will be eligible for a full refund until two weeks after your payment date, or (for courses that have just launched) until two weeks after the first session of the course begins, whichever is later. You cannot receive a refund once you’ve earned a Course Certificate, even if you complete the course within the two-week refund period. See our full refund policy.
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.
