In this video, we show the basics of cryptology (cryptology = cryptography and cryptanalysis).

This video here gives an introduction to passwords. You will see how these are stored and verified. Also, we have a look at password security, thus, we will have a look at different attacks on passwords (brute-force, dictionary, and rainbow tables (short!)). For rainbow tables, we will probably have an additional video in the future. Additionally, we have a look at password space sized and complexity.

This video also gives an introduction to "good" passwords and against which attacks good passwords protect.

On the CrypTool-Online webpage, we have a look at a password generator and a password meter. In CrypTool 2, we show how to store and verify passwords. Also, we show a dictionary attack on SHA-256 hashes passwords.

Really good video! This topic is very very interesting.
Is there a way to add new dictionaries to "play" a little more? Thanks for your work, brillant work!;)
