And more importantly, it must be a substring extracted from the plain text. Suppose the key is “Bob”, since the length of “Bob” is less than the plain text, you will need to pad the key to the same length of the plain text before the encryption:Sun, 12 Apr 2026 18:55:00 GMThttps://stackoverflow.com/questions/41080325/vigen%c3%a8re-cipher-function-implementationAfter watching this tutorial about the Vigenere Cipher, I (hopefully) understand its basic concepts. We want to assign a key to a string, and then shift each letter in the string by the (0-based)Mon, 13 Apr 2026 02:41:00 GMThttps://stackoverflow.com/questions/35375937/vigenere-cypher-in-pythonI'm trying to write a vigenere app in Python. Here is the way the app is supposed to run: run program enter "1" to encrypt or "2" to decrypt a message enter your cypher-key enter the input plaintextTue, 14 Apr 2026 04:48:00 GMThttps://stackoverflow.com/questions/54854357/vigen%C3%A8re-cipher-in-javascript-showing-or-characters0 Here: This implements the Vigenere cipher correctly. It preserves capitilization, encryption and decryption is kept in the same function, and it's easily readable. Your code was likely making the symbol because it's attempting to use unicode values greater than 127, which can make some invalid characters in the output.Sun, 12 Apr 2026 11:53:00 GMThttps://stackoverflow.com/questions/59094006/breaking-vigenere-only-knowing-key-lengthStandard Vigenere interleaves Caesar shift cyphers, specified by the key. If the Vigenere key is six characters long, then letters 1, 7, 13, ... of the ciphertext are on one Caesar shift -- every sixth character uses the first character of the key. Letter 2, 8, 14 ... of the ciphertext use a different (in general) Caesar shift and so on.Sun, 12 Apr 2026 08:54:00 GMThttps://stackoverflow.com/questions/33616943/how-to-decrypt-a-message-using-the-vigenere-cipherAlthough I have managed to encrypt the message "top secret" I am struggling to decrypt messages using the Vigenere Cipher method using the numerical technique I used above. Can someone explain to me how I can decrypt lets say: ISIKIVJIM (the ciphertext from above) to its original plain text message which is "top secret".

Use this technique to create multiple groups of characters to encode.Tue, 14 Apr 2026 16:08:00 GMThttps://stackoverflow.com/questions/60100485/find-length-of-key-in-vigenere-cipherI am new to cryptography kindly help to solve the following vigenere cipher problem with well defined steps Assume you are given a 300 character encrypted message, encrypted in Vigenere cryptosyst...Sat, 11 Apr 2026 23:22:00 GMThttps://stackoverflow.com/questions/28737300/confused-about-vigen%C3%A8re-cipher-implementation-in-javaBackground The code uses the ASCII value of the letters. The letters A-Z are ASCII values 65-90. The idea is to add the two letters together, but wrap around if the values goes above 90 (known as modular arithmetic). So 91 should actually be 65 (i.e. Z + 1 = A). Java provides a % operator for doing modular arithmetic (x % n). However, this is designed to work on a range of numbers 0→ n-1. So ...Sun, 08 Mar 2026 04:49:00 GMT
