CHIPER is a comprehensive collection of classical cryptographic techniques implemented in HTML, CSS, and JavaScript. It serves as an educational resource for anyone interested in understanding the foundations of cryptography. Explore various encryption and decryption algorithms through interactive web-based demonstrations.

• Interactive Demos: Experience encryption and decryption in real-time.
• Algorithms Included:
  • Monoalphabetic Cipher
  • Polyalphabetic Cipher
  • Hill Cipher
  • Playfair Cipher
  • Substitution Cipher
  • Transposition Cipher
• User-Friendly Interface: Designed for students, educators, and cryptography enthusiasts.
• Lightweight and fully browser-based, requiring no additional setup.

A substitution cipher that replaces each letter of the plaintext with another fixed letter based on a key.

A more secure substitution cipher using multiple alphabets to encrypt the message.

A polygraphic substitution cipher based on linear algebra.

A digraph substitution cipher using a 5x5 grid of letters.

Replaces characters in the plaintext with corresponding characters from a substitution key.

Rearranges the letters of the plaintext to create ciphertext based on a fixed rule.
