Introduction to cryptography

I teach Introduction to cryptography [NDMI100] in the summer semester of 2025/2026. The lecture will cover the basics of both theoretical and practical cryptography, focusing on protocols currently used on the Internet.

Lectures will be on Tuesdays from 10:40 in S3.

If you want to consult anything, please write an e-mail to mares+kry@kam.mff.cuni.cz and we will discuss possibilities.
