Similarly, the second letter of the plaintext is combined with the second letter of the key. int current = (int) sb.charAt(keyspace - (i + 1)); int current = (int) sb.charAt(keyspace - 1). The vigenere cipher is an algorithm that is used to encrypting and decrypting the text. First, select the row of the key letter, find the ciphertext letter's position in that row, and then select the column label of the corresponding ciphertext as the plaintext. A more easy implementation could be to visualize Vigenre algebraically by converting [A-Z] into numbers [025]. Time Complexity : O(n), where n is the length of the string(here str). Better yet, don't test with if and handle different cases, just do this unconditionally: Also, rather than searching for a character in the alphabet, use subtraction: Try different approach? Developed by JavaTpoint. First described by Giovan Battista Bellaso in 1553, the cipher is easy to understand and implement, but it resisted all attempts to break it until 1863, three centuries later.
