7 Best Cryptography Courses on edX
Cryptography underpins the security of digital systems, from protecting communications to safeguarding financial transactions. On this page you will find a curated selection of seven courses hosted on edX that cover a range of topics such as foundational cryptographic concepts, practical security testing, quantum‑safe approaches, and the role of blockchain in modern finance. Each course is offered by a recognised university or institution and priced between $148.99 and $150.00 at the time of writing, though a few listings do not disclose a price.\n\nThe courses differ in depth and focus: some provide a broad introduction to information security, others dive into specialised areas like quantum‑resistant infrastructure or hands‑on penetration testing. Consider your current knowledge, career goals and interest in emerging technologies when choosing which programme aligns best with your learning objectives.

How these 7 courses were chosen
Every course below is a real, currently listed course from edX, matched to "cryptography" by our catalog and ordered by our CourseAsk score. Courses whose own title names the topic rank above those only tagged with it.
The grade on each entry scores how much the provider publishes about the course before you pay — the length and detail of the description, whether it lists learning outcomes and objectives — and whether a named university or institution stands behind it. A is fully documented and institution-backed; E is little more than a title and a price. Courses with almost nothing published are left ungraded rather than marked down, because an unknown course and a poor one are not the same thing.
There are no star ratings on this page — the course feeds we license do not include them, and we would rather leave a column out than fill it with a number we cannot stand behind. What we do have is price: these range from $148.99 to $150.00, as listed by the provider when we last updated the page.

What the prices here tell you
The 4 priced courses on this page run from $148.99 to $150.00, with the middle of the range around $150.00 — a spread of $1.01. The options are closely priced, so cost is unlikely to be your deciding factor. A higher price on this page usually reflects who is behind the course rather than how much material it contains, so it is worth opening two or three at different price points and comparing their syllabus before deciding.
Who is behind these courses
These courses come from edX. Everything on this page is sold on the one platform, so the buying experience is the same whichever you pick. 5 of these are produced by a named university or institution, including Tel Aviv University, University of Denver and Delft University of Technology — which usually means a fixed syllabus and a recognised certificate, rather than an individual instructor’s own course.
Before you enrol
Open the provider’s own page and check three things this comparison cannot tell you: when the course was last updated, what the syllabus actually covers in its later sections, and what recent learners say. Prices shown here are the provider’s listed price when we last rebuilt this page on 18 September 2026 — they change often, and a promotion can move them substantially. We earn a commission if you enrol through our links, which costs you nothing and never affects the order courses appear in.
