For this example we will use: LIME [3] X Research sourceWrite down your message without spaces. No. Tool to decode four-square ciphers. In order to cipher a text, take the first letter of the message and the first letter of the key, add their value (letters have a value depending on their rank in the alphabet, starting with 0). wikiHow is a “wiki,” similar to Wikipedia, which means that many of our articles are co-written by multiple authors. % of people told us that this article helped them. His original cipher was more secure than this. There are online and offline Vigenère deciphers you can use to help decipher your code. In the likely case that they came from encrypting the same plaintext, the distance between them is a multiple of the keyword length. The Vigenère Cipher Encryption and Decryption . Double check to make sure you encipher correctly. For example, this would mean that in a Caesar cipher shift of three: A would become D; B would become E; C would become F etc. The Vigenère cipher is a method of encryption that uses a series of different "Caesar ciphers" based on the letters of a keyword. Implement a Vigenère cypher, both encryption and decryption. For this example we will use: Write down your message without spaces. [1] was used in the encryption process. Vigenere cipher is a polyalphabetical cipher. In the digraph cipher shown here, each plaintext digraph is substituted with a digraph from the square. The Vigenère cipher is a method of encryption that uses a series of different "Caesar ciphers" based on the letters of a keyword. Continue on in this fashion until your entire phrase is ciphered.

Thanks to all authors for creating a page that has been read 354,614 times. Don't apply a Caesar cipher to the original message instead of a transposition cipher, as then both steps can be combined to one Vigenère step and the ciphertext isn't stronger protected.
