# Ghettocrypt
|
||||
*because frankly i have no idea what the fuck i'm doing*
|
||||
<sub>*Please don't use this for anything critical*</sub>
|
||||
|
||||
## What the hell is this?
|
||||
An educational project on implementing a block cipher using a feistel network.
|
||||
To provide at least some security this is using some DES-inspired tactics like *cipher block chaining* and *output feedback modus*.
|
||||
This way this provides relatively good diffusion.
|
||||
|
||||
## Features
|
||||
* It has a very easy syntax
|
||||
* It's slow
|
||||
* It's probably super insecure
|
||||
* It leaves your keys sprinkled in ram
|
||||
* But the syntax is pythonlike easy🙇
|
||||
It's pretty ghetto, you know?
|
||||
|
||||
## What are the actual advantages?
|
||||
* It's two files to import into the project
|
||||
* 1 Line to use
|
||||
* 100% cross plattform
|
||||
|
||||
## When could i use it?
|
||||
* For data obfuscation
|
||||
* If your only other option would be no encryption at all
|
||||
|
||||
### I am not kidding, don't use this for critical stuff! Homebrew ciphers are most often shit!
|
||||
Especially mine!🦯
