The One-time pad uses the same key for encryption and decryption. The key is a random number sequence which is used only once and which hackers can not reproduce. It has been proven that the ‘One-time pad' is a perfect algorithm in terms of security since it uses the following principle: clear text + random sequence = random sequence.
This method has solved the main problem of encryption. However, in order to ensure total security, random sequences must be exchanged securely before use, they must be stored securely, and they must be at least as long as the clear text itself

Companies that use encryption systems from the US can be certain that the US secret services can crack their code without any difficulty.

Total security :  one-time pad
Today, the one-time pad is the only totally reliable process. It was developed at the end of the First World War (introduced by Major Joseph Mauborgne, head of the Encrpytion Section of the US Army), and was then applied to the emergency teleprinters operating between Moscow and Washington. It relies on a code made up of a non-repetitive random sequence of letters. The sender and the receiver encrypt using a sequence, which is then destroyed after use. Given that the code lacks any internal structure, it is impossible for an analyst to decrypt the code. This can be mathematically proven.

The totally unbreakable number does exist !
It is Vernam’s one-time pad, used for example to encrypt the hotline between Washington and Moscow.
