In Part 1, we explored the “why” behind end-to-end encryption (E2EE). In Part 2, you learned to encrypt with AES—fast and safe. Part 3 brought in asymmetric encryption and digital signatures with RSA, solving the key exchange problem. Today, we combine everything: let’s build a…
Asymmetric Encryption and Digital Signatures with RSA in Python - (Part 3 of 5)
August 4, 2025
In the first two parts of this series, you learned the fundamentals of end-to-end encryption and how to implement strong symmetric encryption using AES. Now, let’s tackle asymmetric encryption in Python. This post covers public/private key cryptography, secure key exchange, and digital signatures—all with hands-on…
Here’s a fun thought experiment: imagine you’re sending a postcard through the mail, but instead of the postal workers just seeing the address, they can read your entire message, make copies, store it in their database, and share it with whoever they want. Sounds terrible,…
