If there is an odd number of letters, a Z is added to the last letter.Īfter Split: 'in' 'st' 'ru' 'me' 'nt' 'sz'ġ. Algorithm to encrypt the plain text: The plaintext is split into pairs of two letters (digraphs).The initial alphabets in the key square are the unique alphabets of the key in the order in which they appear followed by the remaining letters of the alphabet in order.If the plaintext contains J, then it is replaced by I. Each of the 25 alphabets must be unique and one letter of the alphabet (usually J) is omitted from the table (as the table can hold only 25 alphabets). The key square is a 5×5 grid of alphabets that acts as the key for encrypting the plaintext.The Playfair Cipher Encryption Algorithm: What are Asymptotic Notations in Complexity Analysis of Algorithmsįor the encryption process let us consider the following example:.SDE SHEET - A Complete Guide for SDE Preparation.Asymptotic Analysis (Based on input size) in Complexity Analysis of Algorithms.
