Some tools are affected by an update and do not function properly or result in error messages. I'm looking into it.

Vigenère cipher decoder

Enter the language, the estimated length of the key word and finally the encrypted text.

Language:
Key length: from to characters (min: 1 - max: 50)
Background

The Vigenère cipher encryption needs a key word (Vigenère cipher). It gets much harder to decrypt the text if the key word is not known. However, there are methods to find the key word and consequently decrypt the text. The method used here first tries to find the length of the key word. If the length is known, the key word will be determined by using a character frequency analysis. The frequency of each character depends on the language, therefore choosing the correct language is important. This methods only performs well if the text is long with respect to the key word. The longer the text, the better.
