A pure python implementation of AES 256

Advanced Encryption Standard

Advanced Encryption Standard (AES) is the current unbreakable block cipher which is used in almost every application where symmetric encryption is needed. There are 3 versions of AES

• 128 bit
• 192 bit
• 256 bit

Project Details

This implementation of AES only supports 256-bit encryption and is fully capable of encrypting/decrypting text and binary files. There are two options for key selection:

• Short Key
• 256-bit hexadecimal key (A sample 'key_file' has been given to show how this works)

Usage

• pip install -r requirements.txt
• chmod +x aes.py
• Type in ./aes.py to get the help menu

Encrypt/Decrypt files using 256 bit AES

Usage: aes256.py [raw_key/short_key] [<key_file>/<paraphrase>] [encrypt/decrypt] <path to input file> <path to output file>

raw_key: Use exact 256 bit key (Should be provided as space-separated hex dump in key_file)
short_key: Use sha256 to convert secret paraphrase into 256 bit key

This implementation is free to use. However, if this helps you in any way, you can appreciate my work by starring and forking this repository before use.
