Print('Hacking key #%s: %s' % (key, translated))Ĭonsider the cipher text encrypted in the previous example. Message = 'GIEWIVrGMTLIVrHIQS' #encrypted message The program implementation for hacking Caesar cipher algorithm is as follows − This technique does not demand much effort and is relatively simple for a hacker. One of such possibility is Brute Force Technique, which involves trying every possible decryption key. The cipher text can be hacked with various possibilities. The plain text character is traversed one at a time.įor each character in the given plain text, transform the given character as per the rule depending on the procedure of encryption and decryption of text.Īfter the steps is followed, a new string is generated which is referred as cipher text. You can see the Caesar cipher, that is the output as shown in the following image − Explanation # Encrypt lowercase characters in plain text # Encrypt uppercase characters in plain text The program implementation of Caesar cipher algorithm is as follows − In the history, it was regularly used for protecting sensitive political and military information. It is significantly more secure than a regular Caesar Cipher. The following diagram depicts the working of Caesar cipher algorithm implementation − Vigenere Cipher was designed by tweaking the standard Caesar cipher to reduce the effectiveness of cryptanalysis on the ciphertext and make a cryptosystem more robust. It is simple type of substitution cipher.Įach letter of plain text is replaced by a letter with some fixed number of positions down with alphabet. This is the advantage of using a polyalphabetic cipher over an affine monoalphabetic substitution cipher, in other words: the same letter is not always encrypted the same way. To evade this analysis our secrets are safer using the Vigenère cipher. The algorithm of Caesar cipher holds the following features −Ĭaesar Cipher Technique is the simple and easy method of encryption technique. The Caesar cipher is a method of message encryption easily crackable using frequency analysis. This chapter talks about Caesar cipher in detail. In the last chapter, we have dealt with reverse cipher. Decryption of Simple Substitution Cipher.
