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 :
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
