The study on design and implementation of end to end encrypted Short Message Service (SMS) using hybrid cipher algorithm is motivated by high rate of insecurity of data observed during Short Message Service (SMS) on Mobile devices. SMS messages are one of the popular ways of communication. The aim therefore is to design a software for end to end encryption short message service (SMS) that can. As in case of substitution cipher, cryptanalysis is possible on the Playfair cipher as well, however it would be against 625 possible pairs of letters 25x25alphabets instead of 26 different possible alphabets. The Playfair cipher was used mainly to protect important, yet non-critical secrets, as it is quick to use and requires no special equipment. The Playfair cipher is one of the traditional ciphers which comes under the category of substitution ciphers. In Playfair Cipher, unlike traditional cipher, we encrypt a pair of alphabets (digraphs) instead of a single alphabet. In Playfair cipher, initially, a key table is created. The key table is a 5×5 matrix consisting of alphabets that. Playfair cipher, type of substitution cipher used for data encryption. In cryptosystems for manually encrypting units of plaintext made up of more than a single letter, only digraphs (pairs of letters) were ever used. By treating digraphs in the plaintext as units rather than as single letters, the extent to which the raw frequency distribution survives the encryption process can be. Playfair is digraph substitution cipher which need a 5×5 matrix, in which the key word is written first and the remaining cells of the matrix are filled with different letter of alphabets with I and J taken in the similar cell. The message is divided into digraphs, in which re-currenting letters in the equal pair are divided by filler letter X.
Cryptography. In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption —a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code. In common parlance, "cipher" is synonymous.

The Playfair cipher or Playfair square or Wheatstone-Playfair cipher is a manual symmetric encryption technique and was the first literal digram substitution cipher. The scheme was invented in 1854 by Charles Wheatstone, but bears the name of Lord Playfair for promoting its use. The technique encrypts pairs of letters (bigrams or digrams.
Playfair cipher is an illustration of substitution cipher. The classical playfair cipher has a 5×5 matrix. To increase the resistance of playfair cipher, this paper proposes to introduce double Myszkowski transposition on a modified 6×6 playfair matrix. The 6×6 matrix includes the all the alphabets along with the single digit numbers. A.
The 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.

Here are 16 of the top annoyances. .
(ii)Playfair cipher . The best known multiple letter encryption cipher is the playfair, which treats digrams in the plaintext as single units and translates these units into cipher text digrams. The playfair algorithm is based on the use of 5x5 matrix of letters constructed using a keyword. Let the keyword be „monarchy ‟. The matrix is.
