In particular, the certification method uses a variable encryption key system based on encryption keys of a certification medium and inherent information of computer hardware. In the certification method, a certification medium is provided to the user, the certification medium is prepared by compilation of some pieces of encryption operation formula for certification into an execution file. When a user gains an access to the Internet for Internet use or certification, the remaining pieces of the certification formula are transmitted to the medium, thereby combining all the pieces of certification formula, forming a complete certification formula. Hardware information of the user computer is inputted thereinto, generating a unique value of encryption as certification information.
