"WebThe one time pad (OTP) is a type of stream cipher that is a perfectly secure method of encryption. It’s very simple to implement and is perfectly secure as long as the length of the key is greater than or equal to the length of the message. That’s its major downfall. However, it also requires that the key never be used more than once. " - Diana cryptosystem one time pads
