Long-term offline management of cryptographic parameters

An apparatus for the interception-proof transmission of at least one cryptographic parameter from a user to an encrypted offline storage medium, the cryptographic parameter consisting of information essential for the functioning of a cryptographic system, the apparatus comprising:

• a manipulation apparatus;
• a substrate;
• and
• an upper plate, wherein said upper plate comprises a multitude of indicia, wherein each indicium has a corresponding manipulation indicator, and
• wherein said multitude of indicia are provided in a number of encryption units on the upper plate, whereby the number of encryption units is at least equal to a character length of the at least one cryptographic parameter, whereby each of said number of encryption units comprises at least an equal number of indicia to a number of characters in a writing system of the at least one cryptographic parameter and whereby the indicia of each encryption unit correspond with a random sequence of each of the characters in said writing system;
• and wherein the cryptographic parameter is provided in a hexadecimal numeral system.
