Description
Technical Field
The invention relates to the technical field of computers, in particular to a registration code generation method and device and a software registration method and device.
Background
Software developers often provide software for potential customers to try out in order to promote the software, and meanwhile, in order to protect the benefits of the software developers, the software developers can limit the functions of software of trial versions. Firstly, a software developer provides trial version software with partial cut-off functions for a customer to experience, and the customer provides full-function software with a formal version only after formal purchase; secondly, the software developer provides full-function trial version software with a service life for the trial of the client, and a formal version is required to be purchased and installed after the trial is over; thirdly, the software developer provides full-function software for the customer to try out, but the software defaults to have a service life, and after the service life, the software developer must ask for a License file or input a registration code to normally use the software. In these three ways, the software of the cutting function will make the user experience bad on trial, and may lose the potential customers. Or the trial software with the cutting function can meet the requirements of the customers, so that the customers do not purchase power further, which is equivalent to providing free software. The full-function trial software with the service life is different from the formal software in program files, so that the software needs to be reinstalled or upgraded after being purchased, and smooth transition from trial to formal use cannot be realized.
The License file authorization mode can be used by a plurality of groups of information unit control software, but the License file generally has a large file volume, is not beneficial to human reading and memory, is difficult to transmit through telephone and short message, is not suitable for batch use, and is even impossible to manually input the content of the License file on a target machine applied like an ATM. Although the software using the registration code is convenient to input, the registration code contains a few information units and has a single function, and whether the software can be used continuously can be determined only by identifying the valid or invalid state of the registration code. The trial duration of the trial version software with the service life in the License file or registration code mode is fixed, flexible control cannot be achieved, and the condition of use can be continuously tried after a customer tries to expire and the system is reinstalled.
Therefore, a method for conveniently inputting and flexibly controlling the software use permission is needed, which can meet the requirements of users and effectively protect the software property rights.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flowchart of a registration code generation method provided in embodiment 1 of the present invention. The registration code generation method shown in fig. 1 includes the steps of:
s11, generating a first intermediate ciphertext through a first encryption algorithm based on the machine code and the software product password;
s12, generating an authorization information ciphertext according to a plurality of preset software use authorities;
s13, after the first intermediate ciphertext and the authorization information ciphertext are subjected to encryption operation, a registration code ciphertext is generated;
and S14, outputting a character string sequence of the registration code according to the registration code ciphertext.
In specific implementation, the software product password is a product password set by a software developer for software of different versions, is private for the developer and is not open to the outside. Firstly, carrying out encryption operation on the machine code and the software product password to obtain a first intermediate ciphertext, wherein the first intermediate ciphertext comprises information of the machine code and the software product password; secondly, generating an authorization information ciphertext according to a plurality of preset software use authorities, wherein the software use authorities can be set by a software developer aiming at different customer groups in a software development and design stage, and can also be set by a user in a software sale use stage and a formal use stage; and then, after carrying out encryption operation on the first intermediate ciphertext and the authorization information ciphertext, generating a registration code ciphertext, and outputting a character string sequence of the registration code according to the registration code ciphertext. Through the process, the information of the software product password, the machine code and the software use permission three can be integrated in the registration code ciphertext, wherein the machine code and the software product password are used for verifying the software use permission when the software is used, and different software use permissions can be configured to flexibly control the functional module composition, the number of days of use, the number of use times and the like of the software, so that the diversified requirements of users are met, the defects that the existing registration code contains less information and has single function can be effectively overcome, the problems that the license file authorization process is too complicated and the parameters are fixed are avoided, the input can be facilitated, and the control can be flexibly performed.
Preferably, the machine code is generated by performing a Hash operation on the software product password and one or more of the following information: the serial number of a computer hard disk, the serial number of a computer CPU, the MAC address of a computer network card, the system time of first-time calculation of a machine code and the content of a software configuration file. The hard disk number, the CPU number and the MAC address of the network card can be directly read through an API function of an operating system, and the use of the three groups of data can lead the machine code of each physical machine to be different, thereby limiting the possibility that the same registration code can be simultaneously used on a plurality of machines. For example, the hard disk number of a certain computer is HDS722525VLAT80, and the MAC address is 50-7B-9D-C1-A6-96, and these data are generally unique, so that the machine codes corresponding to different computers are different, and therefore, the same registration code can only identify a unique machine and cannot be copied to other machines for use. On the other hand, the machine code is generated by using the system time of the first calculation of the machine code, so that the vulnerability of reinstalling software after the system is reinstalled can be prevented. Because the system time of the machine code is calculated for the first time, on a specific operating system installation example, the current system time is written into the registry in a numerical value with the granularity of millisecond after the machine code is calculated for the first time, and when the machine code needs to be calculated again for the next time, the time value recorded by the registry is read and used, so that the result of calculating the machine code for each time is consistent, but the machine code is changed certainly because the time millisecond value of acquiring the machine code for the first time is difficult to ensure to be the same after the system is reinstalled, and the current registry code can be invalidated due to the change of the machine code. Furthermore, the software configuration content as the machine code calculation input can limit the user from being able to modify the key configuration, for example, some software may display the name of the client company used on the window title, if the content of the client company name is used as the parameter of the computer code, the machine code may change after the user modifies the displayed company name by the software itself, and the change of the machine code may disable the current registration code. Therefore, the machine code is generated through the software configuration content, and the registration code is generated through the machine code, so that illegal copying and pirating use of the software can be prevented. In the above 6 items, the password of the software product is an input item for computing the machine code, and other items are not necessarily all used in computing the machine code, and may be used in combination with one or more optional items in the software function restriction policy. Different software passwords are configured for different software, so that the management of the registration codes of multiple software products by using the same background software is facilitated, and the fact that the registration codes of different software products cannot be used universally can also be realized.
Therefore, the machine code is used for uniquely identifying a software installation environment in a limited range, can be automatically generated on a computer used by a user, and the user can directly view the machine code on a software interface. Preferably, for ease of input considerations, the machine code is all digital and is limited in length to 10 characters, which 10 characters may be a string of digital representations from 0 to 9. The machine code may be repeated over a wide range, but a very small number of repetitions over a limited range will have no impact on sales and use.
Fig. 2 is a schematic flow chart of a registration code generation method according to embodiment 2 of the present invention. Based on embodiment 1, in the registration code generation method shown in fig. 2, the step S13 specifically includes the steps of:
s131, after the first intermediate ciphertext is split into a first part and a second part, the second part of the first intermediate ciphertext and the authorization information ciphertext are subjected to a second encryption algorithm to generate a temporary ciphertext;
s132, combining the first part of the first intermediate ciphertext and the temporary ciphertext to generate a second intermediate ciphertext, and generating a third intermediate ciphertext through the first encryption algorithm;
and S133, after the third intermediate ciphertext is split into a first part and a second part, combining the first part of the third intermediate ciphertext and the temporary ciphertext to generate a registration code ciphertext.
The operation of the embodiment of the present invention will be described in detail below with reference to fig. 3. In specific implementation, a machine code S provided by a user is received, the machine code S and a software product password K are used as input, a first intermediate ciphertext M1 is generated through a first encryption algorithm, and the first intermediate ciphertext is split into a first part M1-1 and a second part M1-2; generating an authorization information ciphertext P according to a plurality of preset software use authorities; generating a temporary ciphertext R1 through a second encryption algorithm using the second portion M1-2 of the first intermediate ciphertext and the authorization information ciphertext P; then, combining the first part M1-1 of the first intermediate ciphertext with the temporary ciphertext R1 to generate a second intermediate ciphertext M2, and generating a third intermediate ciphertext M3 through a first encryption algorithm; then, the third intermediate ciphertext M3 is split into a first part M3-1 and a second part M3-2, and the first part M3-1 and the temporary ciphertext R1 of the third intermediate ciphertext are combined to generate a registration code ciphertext M4; and finally, outputting a character string sequence R of the registration code according to the registration code ciphertext M4. In the process, a plurality of rounds of encryption operation can be performed through the first encryption algorithm, so that the unrepeatability of the registration codes is facilitated, the cracking difficulty of the registration codes is increased, and the property right of software is protected. Through the process, the registration code comprises three kinds of information of machine code, software product password and a plurality of software authorities, wherein the machine code can prevent the software from being illegally copied and installed, reinstalled by a reinstallation system, reinstalled after the appointed trial condition is expired and the like, different software product passwords ensure that a software developer can use the same software registration protection method to protect various software products, and moreover, the setting of the authority of different software can meet the diversified requirements of different users, the control is flexible, therefore, the scheme can effectively overcome the defects of less information and single function of the existing registration code, avoid the problems of complicated authorization process and fixed parameters when license files are used, facilitate the input of users, and only the registration code needs to be replaced when the trial software stage is switched to the formal use stage, and reinstallation is not needed.
Preferably, the authorization information ciphertext comprises an information unit consisting of modules, an information unit for limiting times, an information unit for limiting the number of days of software use, an information unit for limiting dates, an information unit for the maximum number of connections of the client, an information unit for the maximum number of users simultaneously used, an information unit for the maximum throughput or an information unit for supporting the maximum number of CPUs. The authorization information ciphertext contains information of a plurality of software use authorities, wherein the authorization information ciphertext can comprise a module identifier, two counter initial values and time limit. One for number counting and the other for number of days counting. The number count may be a maximum connection number count of the client, a maximum simultaneous use user number count, a maximum throughput count, or a maximum number count of the supported CPUs, and may be set according to different requirements of the users. Correspondingly, when the software is started or in a certain period during the running of the software, the software is checked and authorized, whether the check item is registered or not, the number of days of use, whether the service life is up or not, whether the designated module is available or not and the like are achieved.
Preferably, the length of the first intermediate ciphertext and the machine code ciphertext may 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 relation:
X+Y＝16，X>0&Y>0
wherein, 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 number of bytes occupied by the second part of the first intermediate ciphertext or the second part of the third intermediate ciphertext. And 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 application, the number of bytes X occupied by the first part is smaller than the number of bytes Y occupied by the second part, so that the register ciphertext can be ensured to have enough storage space to include the required software use permission (generally, Y is larger than or equal to 8). As can be seen from the above process, the cipher text of the registration Code takes 16 bytes, that is, 128 bits, and 128 bits can be converted into 32 characters through an ASCII (American Standard Code for information exchange) Code table, and the registration Code is composed of characters of 0 to 9 and a to F for easier input and transfer according to the habit of forming the registration Code.
Further, the first algorithm is a Hash algorithm. The Hash algorithm maps a binary value of arbitrary length to a shorter binary value of fixed length, this small binary value being called the Hash value. The Hash value is a unique and extremely compact 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 exclusive-or encryption algorithm, a cyclic shift encryption algorithm, or a substitution encryption algorithm, which may be exemplified by the following equation:
such as plaintext T, key K; the exclusive or encryption algorithm is E ═ T xor K; the cyclic shift algorithm is that E is T, and the left shift and the right shift are performed circularly (or circularly and rightly); the substitution encryption algorithm is E ═ Table [ K + T mod L ], and L is the size of the substitution Table Table. The cyclic shift is inconvenient to implement in a high-level language, and the substitution encryption needs to construct a substitution mapping table, so that the second encryption algorithm can be preferably an exclusive-or encryption algorithm.
According to the above-mentioned registration code generation method, embodiment 3 of the present invention further provides a software registration method (i.e. an authorization method, which is basically the inverse operation of the above-mentioned registration code generation method) correspondingly, as shown in fig. 4, including the steps of:
s31, based on the machine code and the software product password, a first intermediate ciphertext is formed through a first encryption algorithm, and the first intermediate ciphertext is divided into a first part and a second part;
s32, receiving a registration code input by a user, converting the registration code into a registration code ciphertext, and splitting the registration code ciphertext into a first part and a second part;
s33, combining the first part of the first intermediate ciphertext and the second part of the registration code ciphertext to generate a second intermediate ciphertext, generating a third intermediate ciphertext through a first encryption algorithm, and splitting the third intermediate ciphertext into the first part and the second part;
