Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.
The embodiment of the application discloses a software anti-cracking method, which is applied to a preset system embedded in target software and is shown in figure 1, and the method comprises the following steps:
step S11: acquiring changed configuration data formed by the normal operation of the activated target software.
It will be appreciated that the default system is a set of programs embedded in the target software. Part of configuration data can be changed along with the target software in the normal operation process, so that changed configuration data formed by the normal operation of the target software needs to be acquired, wherein the changed configuration data can be a general term of the changed configuration data and constant configuration data, and the changed configuration data comprises but is not limited to target software version data, activation code failure time data, machine code data corresponding to a machine for installing the target software, a random number with a preset length, the number of devices for installing the target software, activation time data and parity data.
Step S12: and encrypting the changed configuration data to obtain the encrypted changed configuration data.
In this embodiment, after the change configuration data is obtained, the change configuration data is encrypted to obtain encrypted change configuration data.
In a first specific implementation manner, the encrypting the changed configuration data to obtain the encrypted changed configuration data includes: and encrypting the changed configuration data by using an asymmetric encryption algorithm to obtain the encrypted changed configuration data. When the asymmetric encryption algorithm is adopted to encrypt the changed configuration data, the keys used in the encryption and decryption processes are different, and the keys need to be paired for use when the normal encryption and decryption processes are completed, so that the security of the data can be enhanced, the probability of rewriting the configuration data is reduced, and the possibility of cracking the target software is reduced.
In a second specific implementation manner, the encrypting the changed configuration data to obtain the encrypted changed configuration data includes: and encrypting the changed configuration data by using a symmetric encryption algorithm to obtain the encrypted changed configuration data. And when the symmetric encryption algorithm is adopted to encrypt the change configuration data, the keys used for encryption and decryption are the same key. The symmetric encryption algorithm encrypts and decrypts faster, but less secure, than the asymmetric encryption algorithm.
Step S13: updating the encrypted original configuration data pre-stored in the target database and the standby file list by using the encrypted changed configuration data to obtain updated configuration data; the encrypted original configuration data is obtained by encrypting original configuration data obtained by activating the target software by using an activation code, the encrypted original configuration data in the standby file list is encrypted configuration data stored in the standby file list in a fragmentation storage manner in advance, and the total number of file addresses in the standby file list is greater than the number of file fragments corresponding to the encrypted original configuration data.
It can be understood that, after the change configuration data is encrypted, encrypted original configuration data pre-stored in the updated target database of the encrypted change configuration data and the standby file list is obtained; the encrypted original configuration data is obtained by encrypting original configuration data obtained by activating the target software by using an activation code, the encrypted original configuration data in the standby file list is configuration data stored in the standby file list in a fragmentation storage manner in advance, and the total number of file addresses in the standby file list is greater than the number of file fragments corresponding to the encrypted original configuration data. The total number of file addresses in the standby file list is greater than the number of file fragments corresponding to the target data, so that the outside cannot determine which file addresses the file fragments corresponding to the encrypted original configuration data are stored in, and cannot determine which configuration data the current file fragment specifically represents, the probability that the target software is cracked is reduced, and the safety of the target software is improved.
In this embodiment, after obtaining the encrypted changed configuration data, replacing the encrypted original configuration data in the target database with the encrypted changed configuration data to obtain updated configuration data in the target database, dividing the encrypted changed configuration data into file segments of corresponding number according to the number of the file segments of the encrypted original configuration data pre-stored in the standby file list, and replacing the corresponding file segments of the encrypted original configuration data with the file segments of the encrypted changed configuration data according to the target file address or the target file name of the file segments pre-stored for storing the encrypted original configuration data to obtain the updated configuration data in the standby file list. The fragment storage mode is a storage mode of dividing the encrypted original configuration data into a certain number of file fragments and then storing the file fragments.
In this embodiment, the encrypted original configuration data is encrypted original configuration data, and the encrypted original configuration data includes, but is not limited to, the target software version data, the activation code expiration time data, the machine code data, the random number, the device number, the activation time data, and the parity data. The activation code expiration time data represents expiration time of the activation code, and the expiration time can be given by expiration specific years, months and days, such as 1 month and 1 day 2020, or by an effective duration, such as 2 years.
Step S14: comparing first decryption data corresponding to the updated configuration data in the target database with second decryption data corresponding to the updated configuration data in the standby file list.
It can be understood that, during the running process of the target software, the configuration data corresponding to the target software may be modified by a hacker to illegally utilize the target software, so that it is necessary to compare the first configuration data corresponding to the updated configuration data in the target database with the second decryption data corresponding to the updated configuration data in the standby file list, and determine whether the first decryption data and the second decryption data are the same, so as to determine whether the configuration data in the target database or the standby folder is illegally modified. And if the first decrypted data is not the same as the second decrypted data, the configuration data in the target database or the standby file list is illegally modified.
In this embodiment, the encrypted configuration data stored in the target database and the spare file list includes parity data, and when any file fragment corresponding to the encrypted configuration data stored in the spare file list is illegally modified, the modified file fragment can be restored through the parity data and the remaining file fragments, which does not cause the first decrypted data and the second decrypted data to be different. However, when two or more file segments in the encrypted configuration data are illegally modified or the target database is illegally modified, the encrypted configuration data cannot be restored, and the first decrypted data and the second decrypted data are different. Since the set interface in the preset system is not open to the user, there is no configuration data in the target software that can be illegally modified and belongs to the encrypted configuration data.
Step S15: and if the first decrypted data is not the same as the second decrypted data, forbidding enabling the target software and requiring to reactivate the target software.
It is to be understood that when the first decrypted data is not the same as the second decrypted data, the target software is disabled and re-activation of the target software is required; and when the first decrypted data is the same as the second decrypted data, controlling the target software to normally run.
Therefore, the method comprises the steps of firstly acquiring change configuration data formed by the normal operation of the activated target software; encrypting the change configuration data to obtain encrypted change configuration data; updating the encrypted original configuration data pre-stored in the target database and the standby file list by using the encrypted changed configuration data to obtain updated configuration data; the encrypted original configuration data is obtained by encrypting original configuration data obtained by activating the target software by using an activation code, the encrypted original configuration data in the standby file list is encrypted configuration data stored in the standby file list in a fragmentation storage manner in advance, and the total number of file addresses in the standby file list is greater than the number of file fragments corresponding to the encrypted original configuration data; comparing first decryption data corresponding to the updated configuration data in the target database with second decryption data corresponding to the updated configuration data in the standby file list; and if the first decrypted data is not the same as the second decrypted data, forbidding enabling the target software and requiring to reactivate the target software. Therefore, the method comprises the steps of firstly obtaining changed configuration data formed by normal operation of target software, encrypting the changed configuration data to update encrypted original configuration data pre-stored in a target database and a standby file list, comparing first decryption data corresponding to the updated configuration data in the target database with second decryption data corresponding to the updated configuration data in the standby file list, and if the first decryption data is different from the second decryption data, indicating that the configuration data in the target database or the standby file list is modified, so that the target software is cracked, starting the target software is forbidden, the target software is required to be reactivated, the software can be prevented from being cracked, and illegal use of the software is avoided.
Referring to fig. 2, an embodiment of the present application discloses a specific software anti-cracking method, which is applied to a preset system embedded in target software, and the method includes:
step S21: and acquiring changed configuration data formed by the normal operation of the activated target software by using a set interface in the preset system.
In this embodiment, the preset system includes two interfaces connected to the target software, i.e., a set interface and a get interface. And acquiring changed configuration data formed by the normal operation of the activated target software by using the set interface. And the set interface acquires the changed configuration data formed by the normal operation of the target software in a Map < String, String > plaintext mode, and then calculates the ciphertext through an encryption algorithm.
Step S22: and encrypting the changed configuration data to obtain the encrypted changed configuration data.
Step S23: updating the encrypted original configuration data pre-stored in the target database and the standby file list by using the encrypted changed configuration data to obtain updated configuration data; the encrypted original configuration data is obtained by encrypting original configuration data obtained by activating the target software by using an activation code, the encrypted original configuration data in the standby file list is encrypted original configuration data stored in the standby file list in a fragmentation storage manner in advance, and the total number of file addresses in the standby file list is greater than the number of file fragments corresponding to the encrypted original configuration data.
Step S24: and reading the encrypted original configuration data from the target database and the standby file list respectively by using a get interface in the preset system, decrypting the encrypted original configuration data, and correspondingly obtaining first decrypted data and second decrypted data.
Step S25: and comparing the first decrypted data with the second decrypted data.
In this embodiment, the get interface provides a Map < String, String > interface to the target software. And respectively reading the updated configuration data from the target database and the standby file list by using the get interface, decrypting the configuration data and correspondingly obtaining first decrypted data and second decrypted data. And comparing the first decrypted data with the second encrypted data, and judging whether the first decrypted data is the same as the second decrypted data so as to judge whether the encrypted configuration data in the target database or the standby file list is illegally modified.
Step S26: and if the first decrypted data is not the same as the second decrypted data, forbidding enabling the target software and requiring to reactivate the target software.
Referring to fig. 3, an embodiment of the present application discloses a specific software anti-cracking method, which is applied to a preset system embedded in target software, and the method includes:
step S31: and activating the target software by utilizing the activation code to obtain the original configuration data of the target software.
Step S32: and encrypting the original configuration data to obtain the encrypted original configuration data.
In this embodiment, it is necessary to first obtain original configuration data after the target software is activated by the activation code, and encrypt the original configuration data to obtain encrypted original configuration data. Wherein the activation code is generated by an operator of the target software using an activation code generation system. The activation code generation system is used for generating an activation code. Specifically, the operator of the target software generates a serial number only for the user according to the purchase order of the user, and then generates an activation code by combining the serial number and the machine code of the machine on which the target software is installed by using the activation code generation system. The activation code includes, but is not limited to, the target software version data, the activation code expiration time, the machine code, and the random number, with comma in english separating the different data. And after the target software acquires the activation code, decrypting the activation code by using the preset system, judging whether the activation code is invalid or not according to the activation code invalidation time, if the activation code is invalid, not activating the target software, and if the activation code is not invalid, activating the target software. When the failure time of the activation code is given by a specific year, month and day, the preset system reads the time of a mainboard of a machine provided with the target software to judge whether the activation code is failed or not; when the deactivation time of the activation code is given by the valid duration, the preset system judges whether the valid duration is 0 or not so as to judge whether the activation code is deactivated or not.
In this embodiment, after the target software is activated, the preset system obtains original configuration data, and encrypts the original configuration data to obtain encrypted original configuration data.
Step S33: and storing the encrypted original configuration data into a target database.
It can be understood that, after obtaining the encrypted original configuration data, the preset system may further store the encrypted original configuration data in a target database.
Step S34: and determining a target file address for storing the encrypted original configuration data from a spare file list by using the random number.
In this embodiment, during the process of storing the encrypted original configuration data in the target database, the encrypted original configuration data is further stored in a spare file list in a fragmented manner. The determining, by using the random number, a target file address for storing the encrypted original configuration data from a spare file list includes: determining the number of target file addresses for storing the encrypted original configuration data by using the random number and a preset formula; determining a corresponding number of target file addresses from the standby file list so as to store the encrypted original configuration data; wherein the preset formula isn＝M％NN represents the number of the target addresses, M represents the random number, N represents the total number of file addresses in the spare file list, and% represents a remainder operation. Wherein the spare file columnN file addresses in the table need to be numbered sequentially, and the numbers are 0 to N-1 sequentially. Correspondingly, the corresponding number of target file addresses is determined from the spare file list to store the encrypted original configuration data, and specifically, it can be understood that N file addresses starting from the nth file address in the N file addresses are determined as the target file addresses, and if the number of the file addresses from the nth file address to the N-1 th file address is less than N, the target file addresses start from the 0 th file address after the N-1 th file address. For example, the random number is 100005, and if the total number of file addresses in the spare file list is 20, 100005% 20 is 5, then there are 5 target file addresses for storing the encrypted original configuration data, which are the 5 th, 6 th, 7 th, 8 th, and 9 th file addresses in sequence. The random number is 100012, and if the total number of file addresses in the spare file list is 20, 100012% 20 is 12, and the target file addresses for storing the encrypted original configuration data are 12, which are the 12 th, 13 th, 14 th, 15 th, 16 th, 17 th, 18 th, 19 th, 0 th, 1 st, 2 nd, and 3 rd file addresses in sequence.
Step S35: and dividing the encrypted original configuration data into corresponding number of fragments according to the number of the target file addresses, and sequentially storing the fragments into the target file addresses.
It can be understood that, after the target file address for storing the encrypted original configuration data is determined, the encrypted original configuration data is divided into a corresponding number of fragments, and the fragments are sequentially stored in the target file address. Wherein the dividing the encrypted original configuration data into a corresponding number of segments comprises: and dividing the encrypted original configuration data into a corresponding number of fragments by adopting an average distribution method. If the length of the encrypted original configuration data cannot be averagely distributed into the corresponding number of fragments, the length of the last fragment is determined according to the actual situation. For example, if the length of the encrypted original configuration data is 120 bits, and the number of destination file addresses obtained from the random number is 5, the encrypted original configuration data is divided into 5 segments, and each segment has a length of 24 bits. The length of the encrypted original configuration data is 119 bits, and the number of the target file addresses obtained by the random number is 5, the encrypted original configuration data is divided into 5 segments, each of the first four segments is 24 bits, and the fifth segment is 23 bits. Correspondingly, the segments are sequentially stored in the 5 th, 6 th, 7 th, 8 th and 9 th file addresses.
Step S36: acquiring changed configuration data formed by the normal operation of the activated target software.
Step S37: and encrypting the changed configuration data to obtain the encrypted changed configuration data.
Step S38: updating the encrypted original configuration data pre-stored in the target database and the standby file list by using the encrypted changed configuration data to obtain updated configuration data; the encrypted original configuration data is obtained by encrypting original configuration data obtained by activating the target software by using an activation code, the encrypted original configuration data in the standby file list is encrypted original configuration data stored in the standby file list in a fragmentation storage manner in advance, and the total number of file addresses in the standby file list is greater than the number of file fragments corresponding to the encrypted original configuration data.
Step S39: comparing first decryption data corresponding to the updated configuration data in the target database with second decryption data corresponding to the updated configuration data in the standby file list, and if the first decryption data is different from the second decryption data, forbidding starting of the target software and requiring reactivation of the target software.
An application diagram of the software anti-cracking method disclosed in this embodiment is shown in fig. 4, where the random number is obtained from the activation code, a remainder n is obtained by using the random number to determine the number of target file addresses and the target file address for storing the encrypted original configuration data, and the encrypted original configuration data is stored in the target file addresses in the target database and the backup file list. And acquiring changed configuration data formed by normal operation of target software by using the set interface in the preset system, encrypting the changed configuration data to obtain encrypted changed configuration data, and updating the encrypted original configuration data in the target database and the standby file list by using the encrypted changed configuration data. Respectively reading updated configuration data in the target database and the standby file list by using the get interface in the preset system, decrypting the configuration data, correspondingly obtaining first decrypted data and second decrypted data, comparing the first decrypted data with the second decrypted data, and if the first decrypted data is different from the second decrypted data, controlling the target software to be forbidden to be started by the get interface and requiring to reactivate the target software; and if the first decrypted data is the same as the second decrypted data, controlling the target software to normally run by the get interface.
