Python 2.7.1

In this article, I'll show you how to create a simplistic AES python based text encryptor. You'll need python 2.7 and PyCrypto (found here). The code is fairly simple, a user enters an encryption key (which basically tells the program how to scramble the text, using an algorit ...more

Our mission for this week's Community Byte was to create a Python program to crack web-based passwords, like the ones you would see on an email or router login. I wanted it to be universal in the sense that it could be easily modified and adapted to another website just by cha ...more
