Thank you to ALL who have served. After Vernam's invention of encryption, Joseph Mauborgne proposed that the paper tape contain completely random information.

The two ideas, combined with the one-time use of keys, implement the one-time book , although neither of the two inventors used that name. It is the first and only encryption method for which such a demonstration exists. The Vernam method was used during the Second World War by spies of various nationalities, who were given a random binary sequence with the recommendation to use it with a single encryption process.

At present, the Vernam encryption can be used with different encodings for the alphabet, among them, ASCII encoding can be used , however, by using the XOR operation , the cryptogram can have control codes from the ASCII table, that is, , not printable, so it is necessary to represent the cryptogram with the ASCII code number , generally hexadecimal numbering is used to use only two digits per symbol.
