Encryption (SSL/TLS, RSA, Certificates, CAs)

Показать описание
In this video, we discuss encryption.
What is asymmetric encryption? What are digital signatures? What are certificates and certificate authorities (CAs)? How does the RSA algorithm work (including a 160 line implementation) and how can we use this to SSL/TLS-protect connections in our own networks (key generation, signing, certificates)?

A great example and finally explained in an understandable way. Thanks for that. I was able to reproduce the example without any problems.

Thank you very much for your efforts and videos.

24:00 . Can you make a video on how by implementing the algorithm in the way you did, T^x will result in a loop that only runs no more than 64 times (because we are using 64-bit numbers)?
I feel like this is the first time I have gotten close to understanding the maths behind asymmetric key encryption really.

25:58 . You said (30893, 31621) and (18101, 31621) are the encryption and decryption keys. Is (30893, 31621) one number? or that's two numbers. Same as (18101, 31621).
Thank you for making these videos.

Why is this topic so inherently confusing ? When it comes to the signing part... things can be difficult...
