Аннотация. The article is about to show that One-time pad is unbreakable if all rules are correctly applied. It gives some examples to prove that ciphertext does not leak any information about the plaintext. There are situations when One-time pad can be broken in case it is based on crypto algorithm generator or when it is used more than once. Also, there is analyzed the use of one-time pad in the future.
