Cryptography: A Hands-on Approach (Udemy.com)

I love how this course is full of videos that get you started in cryptography and has a website full of practice labs with books that all correspond. This is a complete and fully supported great beginner learning path for anyone wanting to learn cryptography under the hood!

I personally find these technologies very useful and powerful. Secret-key encryption, hashing, and public-key systems make our digital world safer. I think blockchain and cryptocurrency show how cryptography can build trust without needing middlemen. Overall, I believe these are good innovations that make online communication and transactions more secure and transparent.

Really good course - gave me exactly what I needed by explaining all the things I've been using for years without really understanding them, I'm in a better place now to understand crypto than I was before this course.

Amazing course, so many things/smart words which I have seen/heard before but never understood, now finally it starts to paint a picture. Thanks a lot for these course and all other educational materials.

Understanding the last two chapters was challenging for me due to my limited knowledge of Bitcoin and Blockchain. Additionally, Section 6 (TLS) proved to be a bit difficult. However, the professor did an excellent job explaining these concepts, and I can always revisit the course materials for further clarification. Enrolling in this class has been rewarding overall, and I'm excited about the prospect of taking the Blockchain course in the future.

Especially the Section 7 about Bitcoin and Blockchain was really interesting for me. Professor Wenliang Du is clearly a master in his domain, I had some problems with understanding him sometimes sadly and the subtitles are not accurate (which would have made the language issue not a problem). Thanks a lot for the amazing knowledge!

This course is interesting, informative and provocative. It provides me an alternative perspective that is definitely worth exploring. The instructor is highly intelligent demystify obscure technology.

Really frustrating explanations, that miss important gaps. For example in Section 2, lectures 6 and 7, explaining concepts based on the complete plaint text and cipher text while pointing to individual blocks in the same diagram suggesting we matter is on a block level.

I've been studying modern cryptography on my own for the last year or two and this course has presented a lot of information that I have missed out on. If you have been studying modern cryptography on your own and would like to engage with a course that can help you consolidate your understanding, this course is for you.

The course was very informative and the instructors examples and deep dives with live-drawings helped explain a lot of concepts clearly. I can highly recommend this course both beginners and people who have already been looking into cryptography.
