Secure cryptographic method and suitable equipment

The present invention relates, generally, to an encryption and decryption system, and, more particularly, to an encryption system utilizing a one-time pad key. The task of the invention is to create a practically feasible 100% secure encryption process that is convenient to use. A random numbers generator or random bit generator of outstanding quality is used. Such ideal chances will then be recorded on a data storage device for later encryption purposes. It is important in the context that said storage device would be kept in a safe place or, in the case of encrypted data transmission, would be physically delivered to the recipient via a trustworthy transmission route. Since a secure encryption is only assured if the key or keys is/are used only a single time, it will be expedient, for information to be recorded on the basis of the keys used. Only in this case the one-time pad key can be found again for decryption. For decryption the formerly recorded key is used. Due to the kind of encryption used the recorded key may first be decrypted itself before using the symmetrical encryption/decryption method.
