Hello!
Welcome to another Cryptology 101 article!
Today we will discuss block cipher modes of operation.
I know that the topic might not be fascinating, but it is worth to get through it even once.
Believe it or not, during job interviews, I was asked to briefly describe the topic not once, not twice.
We will also cover Python cryptographic libraries topic.
Let’s go 💣!

Hello!
Today I would like to show you little crypto script, that helped me solve Nested Easter Egg in WebSec 101: JuiceShop ⭐⭐⭐⭐ challenges 2/3!
It’s very basic python implementation of shift cipher, also known as Caesar Cipher, Polybius cipher or ROT 13 (depends on shifting value), which is primitive form of substitution cipher.
I was intending to start writing about things related to cryptography, so we will begin with “back to the roots”!

Hello!
Today I would like to build simple keylogger with Python, just to have a closer look on pynput library and check how difficult it is.
To fulfill my need, for this project I’m going to need fake mail account and several minutes to code 😊
Without further ado, let’s build this simple hacker tool 👻

Hello!
Welcome to the project that, in the beginning, was not bee in my bonnet, but after a light bulb moment, it crystallized.
Today I would like to show you the expansion of the previous Project: Smart Bulb Cop Car, which will imitate TV as a simple line of defense against thieves and burglars. During summertime,e we tend to travel,l and if there is a simple way to increase home security – we should at least give it a try.
