WebThe one-time pad is a cryptography solution that is a significant improvement over the Caesar shift, and still one of the strongest encryption methods we have today. Instead of one consistent shift (like Caesar's shift of 3 letters), every letter in a message gets its own shift, based on a random number. Watch the video above - if the number ...
