Pixel Safe Encryption - Now with AES Encryption on Strings

Run a Remote Environment To Test Pixcryption:

Pixcryption's goal is to offer a new form of steganography/encryption through imagery. It uses a random seeded UUID to generate a user_key which matches RGB perfect values to match to unicode characters. These are stored in a user_key.png file which is used to encrypt and decrypt messages. The speed is getting there but there is 100% room for improvement. I have been working on this for 2 months now and with contributions from @TotallyNotChase he was able to implement AES encryption to the strings passed into Pixcryptions image cipher.

User Key (Compressed in README):

Encrypted Message (Uncompressed):

Hi my name is Max and this is an encrypted image that decrypts into a string. I call it pixelsafe encryption and plan on making it into an awesome thing.

• Python 3.7+
• Pillow
• Numpy
• PyCryptodome

To install run either pip3 install -r requirements.txt or poetry install if you use poetry for dependency management.

To generate a user_key for testing run python3 test.py once and then to test encryption/decryption with said user_key run the test.py file again.

Inside of the core.lib module you will find all functions currently used in the project.

With these you can generate a user key, grab a key_list from a user key, and encrypt/decrypt messages. The implementation is pretty simple and you can take a look at test.py for an example.

This only encrypts unicode characters at the moment which makes it a good choice for messaging. The # of pixels in the image will be == to the # of characters in the string encrypted. This is one security flaw which we need to look into fixing.

If you would like to contribute to pixcryption please submit a pull request. Any help is welcome and all PRs will be reviewed.
