It is a relatively simple cipher in which all you need to know is the value of the rotation of the letters In this cipher, each letter is shifted down by two to three positions. The shift is called rotation or ROT. chronic myeloproliferative disease define

WebbSeveral types of cipher are given as follows: 1. Caesar Cipher In Caesar cipher, the set of plain text characters is replaced by any other character, symbols, or numbers. It is a very weak technique for hiding text. In … WebbHowever, the simple substitution cipher is considered a weak cipher because it is vulnerable to cryptoanalysis. First of all, substitution does not change the letters' frequencies, so if you have a decent amount of enciphered text and you know the language it was written in, you can try frequency analysis.
