WebJun 23, 2024 · One time pad (OTP) is a very simple encryption. Its algorithm is like this. Convert the data you want to encrypt into binary (we call this the plaintext). Generate a true random binary array with the same length as your plaintext (we call this the pad). Perform bitwise XOR between the plaintext and the pad, the result is our cipher.

In cryptography, the one-time pad (OTP) is an encryption technique that cannot be cracked, but requires the use of a single-use pre-shared key that is not smaller than the message being sent. In this technique, a plaintext is paired with a random secret key (also referred to as a one-time pad). Then, each bit or … See more Frank Miller in 1882 was the first to describe the one-time pad system for securing telegraphy. The next one-time pad system was electrical.
