John the Child

A final project for Object Oriented Programming

What is John the Child?

What was once a child-like attempt to be one-man team behind another cryptography application has become a nice starter for anyone interested in developing a project but doesn't want to work from a blank slate. This was originally created to be a final project for an OOP class, and now serves as an instructional tool for software development. Pull requests and issues will likely be ignored unless there's good reason not to.

The Technical Details (thus far...)

• 2+ Ciphers Supported New ciphers yet to come!
• Custom Alphabets that you have to type out if you want to use it
• Multithreaded Hash Cracking Currently supporting MD5, SHA-1, and SHA-256
• Programmed exclusively in Java: I'm sorry.

"He gets the job done!"
