SauES

📝 About

• SauES is a custom encryption standard inspired mainly by the DES standard. It is a symmetric key encryption standard.
• You can play around with the online demo here.

💡Motivation

• The main motivation behind this project was to learn how cryptography and encryption standards work under the hood.

🧪 Specifications
