This video completes the project started previously by tackling the decoding of our visually encrypted data. Using the image file created in the first part, we walk through reading the grid, reconstructing the binary data, and applying the correct password to reverse the AES-256-CBC encryption, ultimately recovering the original message.

Manim community resources ( ) The complete project source code, covering both encryption and decryption, is available on GitHub: [ ] Thank you for following along with this project!
