The VigenÃ¨re Cipher. The VigenÃ¨re cipher, was invented by a Frenchman, Blaise de VigenÃ¨re in the 16th century. It is a polyalphabetic cipher because it uses two or more cipher alphabets to encrypt the data. In other words, the letters in the VigenÃ¨re cipher are shifted by different amounts, normally done using a word or phrase as the encryption key .
History of encryption. The word encryption comes from the Greek word kryptos, meaning hidden or secret. The use of encryption is nearly as old as the art of communication itself. As early as 1900 BC, an Egyptian scribe used non-standard hieroglyphs to hide the meaning of an inscription.
