One-Time Pad is an encryption system that is unbreakable providing certain conditions are met. The conditions that make a one-time pad impossible to crack are also ones that make the technique impractical for many modern applications. Plaintext is paired with a random secret key that is also called a one-time pad. WebDivide the numbers from the one-time pad into pairs and write them in line (in this example we start from the last line in the cipher). Add the numbers from the message. (Attention: use simple arithmetic addition. If sum exceeds 100, write last the two digits in your result) Then the message is divided into groups of five and transmitted. local chorley news today
