🎓 Learn About the Algorithms

Monoalphabetic Cipher

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

Polyalphabetic Cipher

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

Hill Cipher

A polygraphic substitution cipher based on linear algebra.

Playfair Cipher

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

Substitution Cipher

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

Transposition Cipher

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