Cypher Generator

Caesar Cipher: A substitution cipher where each letter in the plaintext is shifted a certain number of places down or up the alphabet.

Atbash Cipher: A specific form of substitution cipher where the letters of the alphabet are reversed (A becomes Z, B becomes Y, etc.).

Vigenère Cipher: A method of encrypting alphabetic text by using a simple form of polyalphabetic substitution.

Transposition Cipher: A method of encryption where the positions of the characters are shifted according to a regular system.

Playfair Cipher: A digraph substitution cipher using a 5x5 grid to encode pairs of letters.

Rail Fence Cipher: A form of transposition cipher that arranges the plaintext in a zigzag pattern.

Columnar Transposition: The plaintext is written in rows and then read out by columns according to a specific sequence.

Affine Cipher: A type of monoalphabetic substitution cipher where each letter in an alphabet is mapped to its numeric equivalent, encrypted using a mathematical function, and then converted back to a letter.

ROT13: A special case of the Caesar cipher where each letter is rotated 13 places.

Polybius Square: Uses a 5x5 grid filled with letters for encryption by coordinates.

Keyword Cipher: A substitution cipher where a keyword determines the mapping of letters.
