WebThe Playfair cipher was invented in 1854 by Charles Wheatstone, but named after lord Playfair who heavily promoted the use of the cipher. It is a polygraphic substitution cipher, which encrypts pair of letters instead of single letters. This makes frequency analysis much more difficult, since there are around 600 combinations instead of 26. WebThe Gronsfeld cipher is, just like the Vigenère cipher a polyalphabetic substitution. Characters are replaced using different alphabetic series and a key word is used for the encryption. The only difference is that the Gronsfeld cipher uses a numeric key. The Gronsfeld cipher can easily be converted to a Vigenère cipher by substitution of the ...
