Affine Cipher Keyed Tool

Affine Cipher Keyed Tool – Encode & Decode Classical Ciphers Online

Discover the power of classical cryptography with our Affine Cipher Keyed Tool! This advanced cipher tool lets you encrypt and decrypt text using the Affine Cipher, one of the most famous substitution ciphers in cryptography history. By combining mathematics with modular arithmetic, the Affine Cipher applies a unique keyed formula to shift letters, making it an excellent way to learn about secure communication and historical code-making.

Perfect for students, puzzle enthusiasts, and cryptography lovers, our tool allows you to enter custom keys (values of ‘a’ and ‘b’) to generate strong encryption patterns. With just one click, you can test, learn, and play with encrypted messages!

Why Use Our Affine Cipher Keyed Tool?

✅ Dual Functionality – Instantly encrypt and decrypt messages.
✅ Customizable Keys – Enter your own keys (a, b) to generate unique ciphers.
✅ Educational Value – Learn how modular arithmetic works in cryptography.
✅ Fast & Free – No downloads, no sign-ups, works directly online.
✅ Cross-Platform – Fully responsive for desktop, tablet, and mobile devices.
