Tool for encoding and decoding with the Caesar cipher, a simple and famous shift cipher that replaces each letter with another one further down the alphabet. Compatible with ROT13 and other variants.

Go ahead and try encoding or decoding some text. The Shifted Alphabet Code is very very easy to do. Begin by writing down the alphabet in order on a piece of paper (or use the one below). Now pick a …

Caesar cipher is a classic encryption method that shifts letters in the alphabet to hide or reveal secret messages. This Caesar cipher decoder makes it easy to encode or decode text using a fixed or …

How's this work? This cypher does basic substitution for a character in the alphabet. Result. Encoded Characters: 0 Encoded Characters Sum: 0. Jack Stromberg\'s site about stuff!.

You can create custom letter-to-letter mappings, use numeric codes, or implement symbol substitutions. The tool also handles special characters and spaces, making it versatile for different coding needs.

This multi decoder is designed to solve a wide variety of codes and ciphers, especially useful for Geocaching. Easy to use for both mobile and desktop browsers!

A monoalphabetical substitution cipher uses a fixed substitution over the entire message. The ciphertext alphabet may be a shifted, reversed, mixed or deranged version of the plaintext alphabet.
