Cryptography with Python 25: Hash function security

Entire course: ➡️ https://www.youtube.com/playlist?list=PLWjMI9CAmVU4–SmpzgswTvxLkZqC9QWn

⏰ Timestamps for content in this video ⏰

00:00 Hash function security
01:01 Requirements on one-wayness
02:13 Requirements on collision resistance
05:05 Requirements on second pre-image resistance
06:32 Insecurity of MD5 and SHA-1, security of SHA-2 and SHA-3

🔷🔷 About 🔷🔷

This Fundamental Cryptography in Theory and Python lesson presents essential security requirements for hash functions to be considered secure. The lesson then presents, why MD5 and SHA-1 are considered insecure hash functions, and why SHA-2 and SHA-3 are considered secure hash functions.
