Tryhackme – Cryptography for Dummies

In this walk through, we will be going through the Cryptography for Dummies room from Tryhackme. This room will teaches you the basics of Cryptography, the types of it and how we can use common hashing algorithm and much more. So let’s get started.

So that was “Cryptography for Dummies” for you. In this short room, we covers the basics of cryptography, types of encryption, hashing, encoding and decoding of data. Well, cryptography is a huge topic and become complex as we progress however this room is a good starting point for anyone who is new in the world of security. On that note, allow me to take a leave and remember to “Hack the Planet” for the meanwhile.
