WebMar 24, 2024 · Vernam Cipher is a cryptographic algorithm to encrypt and decrypt an alphabetic text. In this cipher, we first make the length of the key equal to the message length by repeating the key. Then, we add the ith letter of the message with the ith letter of the key by assigning each letter with the number(eg, A = 0, B = 1, C = 2, etc). hilfe taxfix.de https://inkyoriginals.com
