Description

Registration code generation method and device, software registration method and device

technical field

The invention relates to the field of computer technology, in particular to a registration code generation method and device, and a software registration method and device.

Background technique

In order to promote software, software developers often provide software to potential customers for trial use. At the same time, in order to protect their own interests, software developers will impose certain restrictions on the software functions of the trial version. There are three common methods. One is that software developers provide trial version software with some functions cut off for customers to experience, and the official version of full-featured software is provided only after customers formally purchase; Trial version software is for trial use by customers. After the trial period expires, the official version needs to be purchased and installed; third, the software developer provides full-featured software for trial use by customers, but the software has a default period of use. After the period expires, a license must be obtained from the software developer (Authorization license) file or the software can be used normally only after entering the registration code. Among these three methods, the software with reduced functions will make the user trial experience not good, and may lose potential customers. Or the trial version software with reduced functions can meet customer requirements, resulting in no further purchase motivation for customers, which is equivalent to providing free software. Full-featured trial software with a time limit, because the program files of the trial software are different from those of the official software, the software needs to be reinstalled or upgraded after purchase, which cannot achieve a smooth transition from trial to official use.

The license file authorization method can certainly control the use of software through multiple sets of information units, but the license file is generally large in size, and the content is not conducive to human reading and memory. It is difficult to transfer by phone or text message, and it is not suitable for batch use. It is even more impossible to manually input the content of the License file on a target machine similar to an ATM machine. Although the software that usually uses the registration code is convenient to input, because the registration code contains few information units and has a single function, it can only be determined whether the software can continue to be used by identifying the valid or invalid state of the registration code. The trial period of trial version software with a period of use using license files or registration codes is fixed and cannot be flexibly controlled. There may also be cases where customers continue to use the trial version after reinstalling the system after the trial period expires.

Therefore, there is a need for a method that is convenient for input and can flexibly control software usage rights, which can meet user needs and effectively protect software property rights.

Contents of the invention

The purpose of the embodiments of the present invention is to provide a registration code generation method and device, and a software registration method and device, which can effectively overcome the defects of existing registration codes containing less information and single functions, and avoid the cumbersome and cumbersome authorization process of using license files. The problem of fixed parameters can not only facilitate input, but also allow flexible control.

After the third intermediate ciphertext is split into a first part and a second part, the first part of the third intermediate ciphertext and the temporary ciphertext are combined to generate a registration code ciphertext.

Through multiple combinations and encryption operations, it not only ensures that the registration code includes the information of software product password, machine code and some software usage rights, but also ensures the non-repeatability of the registration code.

As an improvement of the above scheme, the length of the first intermediate ciphertext and the machine code ciphertext is 16 bytes; and the lengths of the first part and the second part of the first intermediate ciphertext or the third intermediate ciphertext satisfy The following relationship:

X+Y=16, X>0&Y>0

Wherein, the X is the number of bytes occupied by the first part of the first intermediate ciphertext or the first part of the third intermediate ciphertext, and Y is the second part of the first intermediate ciphertext or the second part of the third intermediate ciphertext. The number of bytes occupied by the section. The number of bytes occupied by the first part is smaller than the number of bytes occupied by the second part, which can ensure that the registration ciphertext has enough storage space to include the required software usage rights.

As an improvement of the above solution, the second encryption algorithm is an XOR encryption algorithm, a cyclic shift encryption algorithm or a substitution encryption algorithm. And by setting different length components, the method can be applied to different software authorization settings.

As an improvement to the above solution, the first encryption algorithm is a Hash encryption algorithm. Hash encryption algorithm can ensure the integrity and compactness of information.

As an improvement of the above solution, the authorization information ciphertext includes information units composed of modules, information units with limited times, information units with limited days of software use, information units with limited dates, information units with the maximum number of client connections, maximum Simultaneously use information units for the number of users, information units for maximum throughput, or information units for supporting the maximum number of CPUs.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Referring to FIG. 1 , it is a schematic flowchart of a method for generating a registration code provided by Embodiment 1 of the present invention. The method for generating the registration code as shown in Figure 1 includes steps:

S11. Generate a first intermediate ciphertext through a first encryption algorithm based on the machine code and the software product password;

S12. Generate authorization information ciphertext according to several preset software usage rights;

S13. After encrypting the first intermediate ciphertext and the authorization information ciphertext, generate a registration code ciphertext;

S14. Output a character string sequence of the registration code according to the registration code ciphertext.

During specific implementation, the software product password is the product password set by the software developer for different versions of the software, which is privately owned by the developer and not open to the outside world. First, the first intermediate ciphertext is obtained by encrypting the machine code and the software product password, and the first intermediate ciphertext includes the information of both the machine code and the software product password; then, according to several preset software usage rights, generate Authorization information ciphertext, said several software usage rights can be set by software developers for different customer groups in the software development and design stage, and can also be set by users in the software sales and use stage and formal use stage; then, the said After the first intermediate ciphertext and the authorization information ciphertext are encrypted, a registration code ciphertext is generated, and a string sequence of the registration code is output according to the registration code ciphertext. Through the above process, the information of the software product password, the machine code and the software use right can be integrated in the registration code ciphertext, wherein the machine code and the software product password are used to verify the software use right when the software is used, and the configuration Different software usage rights can flexibly control the composition of functional modules, days of use, and times of use of the software to meet the diverse needs of users. Therefore, this solution can effectively overcome the shortcomings of existing registration codes that contain less information and single functions, and avoid The authorization process using license files is too cumbersome and the parameters are fixed, which can not only facilitate input, but also allow flexible control.

Preferably, the machine code is generated by hashing the software product password and one or more of the following information: computer hard disk number, computer CPU number, computer network card MAC address, system time of the first computer code, software Configuration file content. Among them, the hard disk number, CPU number, and MAC address of the network card can be directly read through the API function of the operating system. The use of these three sets of data can make the machine code of each physical machine different, which also limits the number of registration codes for the same registration code. Simultaneous use possible on two machines. For example, the hard disk number of a certain computer is HDS722525VLAT80, and the MAC address is 50-7B-9D-C1-A6-96. These data are generally unique, so the machine codes corresponding to different computers are also different, so the same registration code can only identify unique One machine cannot be copied to other machines for use. On the other hand, using the system time of calculating the machine code for the first time to generate the machine code can prevent the loophole of reinstalling the software after the system is reinstalled. Because, the system time of the first computer code calculation, on a specific operating system installation instance, after the first computer code operation is performed, the current system time is written into the registry with the granularity of milliseconds, and when it is needed next time When calculating the machine code, the time value recorded in the registry will be read and used, which ensures that the result of calculating the machine code is consistent every time. However, after reinstalling the system, it is difficult to ensure that the millisecond value of the time to obtain the machine code for the first time is the same. Therefore, the machine code must change, and the change of the machine code will invalidate the current registration code. Furthermore, the software configuration content can be used as machine code calculation input to restrict users from modifying key configurations by themselves. For example, some software will display the name of the customer company used on the window title. If the content of the customer company name is used as the parameter for calculating the machine code , after the user modifies the software to display the company name, the machine code will change, and the change of the machine code will invalidate the current registration code. Therefore, generating a machine code through software configuration content, and then generating a registration code through the machine code can prevent illegal copying and pirated use of software. For the above 6 items, the software product password is an input item for calculating the machine code. It is not necessary to use all other items when calculating the machine code. You can choose one or a combination of several items according to the software function restriction policy. For different software, different software passwords are configured, which is beneficial to use the same background software to manage the registration codes of multiple software products, and can also realize that the registration codes of different software products cannot be used in common.

Therefore, the machine code is used to uniquely identify a software installation environment within a limited range, and can be automatically generated on the computer used by the user, and the user can directly view the machine code on the software interface. Preferably, for the convenience of input, the machine code is all numbers and the length is limited to 10 characters, and the 10 characters can be represented by a string of numbers from 0-9. The machine code may be repeated in a large range, but a very small amount of repetition in a limited range will not affect sales and use.

Referring to FIG. 2 , it is a schematic flowchart of a method for generating a registration code provided by Embodiment 2 of the present invention. The registration code generating method as shown in Figure 2 is based on Embodiment 1, and the step S13 specifically includes steps:

S131. After splitting the first intermediate ciphertext into a first part and a second part, generate a temporary ciphertext by using a second encryption algorithm with the second part of the first intermediate ciphertext and the authorization information ciphertext;

S132. Combine the first part of the first intermediate ciphertext and the temporary ciphertext to generate a second intermediate ciphertext, and use the first encryption algorithm to generate a third intermediate ciphertext;

S133. After splitting the third intermediate ciphertext into a first part and a second part, combine the first part of the third intermediate ciphertext with the temporary ciphertext to generate a registration code ciphertext.

With reference to FIG. 3 , the working process of the embodiment of the present invention will be described in detail below. During specific implementation, first receive the machine code S provided by the user, use the machine code S and the software product password K as input, generate the first intermediate ciphertext M1 through the first encryption algorithm, and split the first intermediate ciphertext into the first intermediate ciphertext A part M1-1 and a second part M1-2; generate authorization information ciphertext P according to a number of preset software usage rights; combine the second part M1-2 of the first intermediate ciphertext and the authorization information P generates the temporary ciphertext R1 through the second encryption algorithm; then, the first part M1-1 of the first intermediate ciphertext and the temporary ciphertext R1 are combined to generate the second intermediate ciphertext M2, and pass the first The encryption algorithm generates a third intermediate ciphertext M3; then, the third intermediate ciphertext M3 is split into a first part M3-1 and a second part M3-2, and the first part M3-2 of the third intermediate ciphertext is 1 and the temporary ciphertext R1 are combined to generate a registration code ciphertext M4; finally, a character string sequence R of the registration code is output according to the registration code ciphertext M4. In the above process, multiple rounds of encryption operations can be performed by the first encryption algorithm, which is beneficial to the non-repeatability of the registration code, increases the difficulty of deciphering the registration code, and protects the property rights of the software. Through the above process, the registration code includes three kinds of information: machine code, software product password and several software permissions, wherein the machine code can prevent the software from being illegally copied and installed, reinstalling the system and reinstalling, reinstalling after the agreed trial conditions expire, etc. Illegal use of software, and different software product passwords enable software developers to use the same software registration protection method to protect multiple software products. Furthermore, setting different software permissions can meet the diverse needs of different users , the control is flexible, so this solution can effectively overcome the defects that the existing registration code contains less information and single function, and avoids the problem that the license file authorization process is too cumbersome and the parameters are fixed, it is convenient for users to input, and it is switched to during the trial software stage In the official use stage, only the registration code needs to be replaced, and no reinstallation is required.

Preferably, the authorization information ciphertext includes information units composed of modules, information units of limited times, information units of limited days of software use, information units of limited dates, information units of the maximum number of client connections, maximum simultaneous users The number of information units, the information unit with the maximum throughput, or the information unit that supports the maximum number of CPUs. The authorization information ciphertext includes information on various software usage rights, wherein the authorization information ciphertext may include a module identifier, two initial values of counters and a time limit. Among them, one counter is used for counting the number of times, and the other counter is used for counting the number of days. The number of counts can be the count of the maximum number of client connections, the maximum number of simultaneous users, the maximum throughput, or the maximum number of supported CPUs, which can be set according to different needs of users. Correspondingly, when the software is started, or within a certain period of time when the software is running, the software will be checked and authorized, and the check items include whether it is registered, the number of days of use, whether the use period has been reached, whether the specified module is available, etc.

Preferably, the length of the first intermediate ciphertext and the machine code ciphertext can be set to 16 bytes; and the lengths of the first part and the second part of the first intermediate ciphertext or the third intermediate ciphertext satisfy The following relationship:

X+Y=16, X>0&Y>0

Wherein, the X is the number of bytes occupied by the first part of the first intermediate ciphertext or the first part of the third intermediate ciphertext, and Y is the second part of the first intermediate ciphertext or the second part of the third intermediate ciphertext. The number of bytes occupied by the section. The number of bytes, Y is the number of bytes occupied by the second part of the first intermediate ciphertext or the second part of the third intermediate ciphertext. In practical applications, the number of bytes X occupied by the first part is smaller than the number of bytes Y occupied by the second part, which can ensure that the registration ciphertext has enough storage space to include the required software usage rights (usually Y≥8). It can be seen from the above process that the ciphertext of the registration code occupies 16 bytes, that is, 128 bits. Using hexadecimal, 128 bits can be converted into 32 characters, according to the habit of registration code composition, and for more convenient input and transmission, the registration code is composed of characters 0-9, A-F.

Further, the first algorithm is a Hash algorithm. The Hash algorithm maps a binary value of any length to a shorter fixed-length binary value, and this small binary value is called a Hash value. Hash value is a unique and extremely compact numerical representation of a piece of data. If there is a change in the input data, the Hash value will also change. Among them, the more commonly used Hash algorithms are MD5 and SHA.

Preferably, the second encryption algorithm is an XOR encryption algorithm, a cyclic shift encryption algorithm or a substitution encryption algorithm, and these algorithms can be illustrated by the following formula:

Such as plaintext T, key K; XOR encryption algorithm is E=T xor K; cyclic shift algorithm is E=T cyclic left shift K (or cyclic right shift); substitution encryption algorithm is E=Table[K+T mod L], L is the size of the table. Among them, the cyclic shift is inconvenient to implement in a high-level language, and the substitution encryption needs to construct a substitution transformation table, so the second encryption algorithm can preferably be an XOR encryption algorithm.

According to the registration code generation method described above, Embodiment 3 of the present invention also provides a corresponding software registration method (that is, an authorization method, which is basically the inverse operation of the above registration code generation method), as shown in Figure 4, including steps:

S31. Based on the machine code and the software product password, use the first encryption algorithm to generate a first intermediate ciphertext, and split the first intermediate ciphertext into a first part and a second part;

S32. Receive the registration code input by the user and convert it into a registration code ciphertext, and split the registration code ciphertext into a first part and a second part;

S33. Combine the first part of the first intermediate ciphertext and the second part of the registration code ciphertext to generate a second intermediate ciphertext, and use the first encryption algorithm to generate a third intermediate ciphertext, and convert the The third intermediate ciphertext is split into the first part and the second part;

S34. When the first part of the third intermediate ciphertext is equal to the first part of the registration code ciphertext, determine that the registration code is valid, and save the registration code ciphertext to the registry;

S35. When the registration code is valid, pass the second part of the registration code ciphertext and the second part of the first intermediate ciphertext through the second encryption algorithm to obtain the authorization information ciphertext, and analyze the authorization information ciphertext to obtain the software product authorization information.

During specific implementation, the machine code S and the software product password K are first encrypted into the first intermediate ciphertext M1 through the first encryption algorithm, and the first intermediate ciphertext M1 is split into the first part M1-1 and the second part M1- 2; then convert the registration code R input by the user into a registration code ciphertext M4, split the registration code ciphertext into a first part M4-1 and a second part M4-2; convert the first intermediate ciphertext The first part M1-1 of the registration code and the second part M4-2 of the registration code ciphertext are combined to generate the second intermediate ciphertext M2, and the third intermediate ciphertext M3 is generated by the first encryption algorithm, and the third intermediate The ciphertext is split into a first part M3-1 and a second part M3-2; when the first part M3-1 of the third intermediate ciphertext is equal to the first part M4-1 of the registration code ciphertext, then determine The registration code is valid, and the registration code R is saved to the registry; when the registration code is valid, the second part M4-2 of the registration code ciphertext and the second part M1-2 of the first intermediate ciphertext are passed The second encryption algorithm obtains the authorization information ciphertext P, and analyzes the authorization information ciphertext P to obtain the authorization information of the software product. It can be known from the registration code generation process and the corresponding software registration process that the first encryption algorithm is an irreversible algorithm, preferably a Hash encryption algorithm, and the second encryption algorithm is a reversible algorithm, preferably an XOR encryption algorithm. By verifying the right to use the software on the first part of the ciphertext of the registration code, illegal use of software such as illegal copying of the software, reinstallation after reinstalling the system, etc. can be prevented, and the property rights of the software are effectively protected; After verification, the authorization information is obtained by analyzing the ciphertext of the authorization information, and the software usage rights such as the composition of software function modules, the number of times of use, the number of days of use, and the period of use can be flexibly configured, which can meet the diverse needs of users and effectively overcome the existing registration requirements. The code contains the defects of less information and single function, and avoids the problem of too cumbersome and fixed parameters in the authorization process of using the license file, which can not only facilitate input, but also allow flexible control.
