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.
