Problems solved by technology

[0002] For the sake of safety or profit, it is necessary to add an authorization password when the program is executed. The general program encryption method is to put the password somewhere in the program, which is easy to be found and modified by the cracker, so that the encryption fails.

Abstract

The invention discloses a program-based characteristic numeric code encryption method. The method includes the steps of embedding a set of random numbers to an encrypted program, designing a characteristic numeric code algorithm and embedding the algorithm to the encrypted program, issuing the encrypted program and a corresponding characteristic numeric code serving as a user password to a user side, entering the password in a password dialog box by a user to start the program, calculating a characteristics numeric code of the program through the characteristic numeric code algorithm embedded into the program, comparing whether the password entered by the user is identical to the password of the program or not, if so, executing the program, and if not, quitting the program. The program-based characteristic numeric code encryption method reduces the risk of finding and cracking of the password carried with the program.

Description

technical field [0001] The invention relates to the field of computer software, in particular to a method for encrypting characteristic digital codes based on the program itself. Background technique [0002] For the sake of safety or profit, it is necessary to add an authorization password when the program is executed. The general program encryption method is to put the password somewhere in the program, which is easy to be found and modified by the cracker, so that the encryption fails. Contents of the invention [0003] Purpose of the invention: Aiming at the problems and deficiencies in the prior art above, the purpose of the present invention is to provide a method for encrypting characteristic digital codes based on the program itself, which reduces the risk of encryption failure due to password discovery and modification, and is easy to implement. [0004] Technical solution: In order to achieve the above-mentioned purpose of the invention, the technical solution ad...
