The Caesar cipher (or Caesar code) is a monoalphabetic substitution cipher, where each letter is replaced by another letter located a little further in the alphabet (therefore shifted but always the same for given cipher message).

Feb 13, 2025 · Cipher: A method or a set of rules for performing encryption or decryption of information – a step by step process. Encryption: The transformation of plaintext to the ciphertext through the use of a cipher. Decryption: The act of moving …

Jun 27, 2024 · What is Caesar Cipher Technique? The Caesar cipher is a simple encryption technique that was used by Julius Caesar to send secret messages to his allies. It works by shifting the letters in the plaintext message by a certain number of …

The Vigenère cipher is an improvement of the Caesar cipher, by using a sequence of shifts instead of applying the same shift to every letter. A variant of the Vigenère cipher, which uses numbers instead of letters to describe the sequence of shifts, is called a Gronsfeld cipher.

Tool to identify/recognize the type of encryption/encoding applied to a message (more 200 ciphers/codes are detectable). Cipher identifier to quickly decrypt/decode any text.

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!

Tool to decrypt/encrypt by ROT. The code ROT for Rotation (which most common variant is Caesar Cipher) is the easiest shift-based encryption cipher.

Caesar cipher: Encode and decode online Method in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. The method is named after Julius Caesar, who used it in his private correspondence.

The Caesar cipher is one of the earliest and simplest ciphers that were invented. It works like this: First, choose some text that you want to encrypt. Let's choose the text "eat". Next, pick a number. It can be positive or negative. Let's choose "-3" for this example. This will be our "key" that will allow us to encrypt and decrypt the message.
