Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

The embodiment of the present application discloses a software anti-cracking method. As shown in FIG. 1, it is applied to a preset system embedded in target software, and the method includes:

Step S11: Obtain the changed configuration data formed by the normal operation of the target software after activation.

It is understandable that the preset system is a set of programs embedded in the target software. During the normal operation of the target software, part of the configuration data will change accordingly. Therefore, it is necessary to obtain the change configuration data formed by the normal operation of the target software. The change configuration data may be a comparison between the changeable configuration data and the changeable configuration data. The general term for constant configuration data. The changed configuration data includes but is not limited to target software version data, activation code expiration time data, machine code data corresponding to the machine on which the target software is installed, random numbers with a preset length, and The number of devices installed by the target software, activation time data, and parity data.

Step S12: Encrypt 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 the encrypted change configuration data.

In a first specific implementation manner, the encrypting the changed configuration data to obtain the encrypted changed configuration data includes: encrypting the changed configuration data using an asymmetric encryption algorithm to obtain the encrypted changed configuration data. When an asymmetric encryption algorithm is used to encrypt the changed configuration data, the keys used in the encryption and decryption process are different. To complete the normal encryption and decryption process, they must be paired and used, which can enhance data security and reduce The probability of configuration data being rewritten reduces the possibility of target software being cracked.

In a second specific implementation manner, encrypting the changed configuration data to obtain the encrypted changed configuration data includes: encrypting the changed configuration data using a symmetric encryption algorithm to obtain the encrypted changed configuration data. When the symmetric encryption algorithm is used to encrypt the changed configuration data, the key used for encryption and decryption is the same key. Compared with the asymmetric encryption algorithm, the symmetric encryption algorithm has faster encryption and decryption speed, but the security is relatively lower.

Step S13: Use the encrypted changed configuration data to update the encrypted original configuration data pre-stored in the target database and the backup file list to obtain the updated configuration data; wherein, the encrypted original configuration data is for the activation of the original configuration data using the activation code. The original configuration data obtained after the target software is encrypted, and the encrypted original configuration data in the backup file list is the encrypted configuration data that is stored in the backup file list in advance according to the slice storage method And, the total number of file addresses in the backup file list is greater than the number of file fragments corresponding to the encrypted original configuration data.

It is understandable that after encrypting the changed configuration data, the encrypted original configuration data stored in advance in the updated target database and the backup file list is obtained after the encrypted changed configuration data; wherein, the encrypted original configuration data is Data obtained by encrypting the original configuration data obtained after activating the target software with an activation code, and the encrypted original configuration data in the backup file list is stored in the backup file list in advance according to a fragmented storage method And the total number of file addresses in the backup 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 backup file list is greater than the number of file fragments corresponding to the target data, so that the outside world cannot determine under which file addresses the file fragments corresponding to the original configuration data after encryption are stored, or the current file fragments. Which specific configuration data is displayed reduces the probability of the target software being cracked and improves the security of the target software.

In this embodiment, after the encrypted changed configuration data is obtained, the encrypted original configuration data in the target database is replaced with the encrypted changed configuration data to obtain the updated configuration data in the target database, and according to The number of file fragments of the encrypted original configuration data pre-stored in the backup file list, the encrypted changed configuration data is divided into corresponding number of file fragments, and the encrypted original configuration data is stored in advance according to the number of file fragments. The target file address or target file name of the file segment of the data is replaced with the encrypted file segment of the changed configuration data for the corresponding file segment of the original configuration data after encryption to obtain the updated configuration data in the backup file list. The fragmented storage mode is a storage mode in which the encrypted original configuration data is divided into a certain number of file fragments and then stored.

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, and the machine code Data, the random number, the number of devices, the activation time data, and the parity data. Wherein, the activation code expiration time data represents the expiration time of the activation code, and the expiration time can be given by the specific year, month and day of the expiration, for example, January 1, 2020, or can be given by the validity period, for example, valid The duration is 2 years.

Step S14: Compare the first decrypted data corresponding to the updated configuration data in the target database with the second decrypted data corresponding to the updated configuration data in the backup file list.

It is understandable that during the operation of the target software, the configuration data corresponding to the target software may be modified by hackers to illegally use the target software. Therefore, the updated configuration in the target database needs to be modified. The first configuration data corresponding to the data is compared with the second decrypted data corresponding to the updated configuration data in the backup file list to determine whether the first decrypted data and the second decrypted data are the same, so as to determine Whether the configuration data in the target database or the backup folder is illegally modified. If the first decrypted data is different from the second decrypted data, the configuration data in the target database or the backup file list has been illegally modified.

In this embodiment, the encrypted configuration data stored in the target database and the backup file list includes parity data, when any one of the backup file lists stores the file corresponding to the encrypted configuration data When a fragment is illegally modified, the parity data and the remaining file fragments can be used to restore the modified file fragment without causing the first decrypted data and the second decrypted data to be different. However, when two or more file fragments in the encrypted configuration data are illegally modified, or the target database is illegally modified, the encrypted configuration data cannot be restored, which will cause the first decrypted data and The second decrypted data is different. Since the set interface in the preset system is not open to users, there is no configuration data in the target software that can be illegally modified and belongs to the encrypted configuration data.

Step S15: If the first decrypted data is not the same as the second decrypted data, the target software is prohibited from being activated, and the target software is required to be reactivated.

It is understandable that when the first decrypted data is different from the second decrypted data, the target software is forbidden to be activated, and the target software is required to be reactivated; when the first decrypted data is different from the second decrypted data, When the second decrypted data is the same, the target software is controlled to run normally.

Referring to FIG. 2, the 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: Use the set interface in the preset system to obtain the changed configuration data formed by the normal operation of the activated target software.

In this embodiment, the preset system includes two interfaces connecting the target software, namely, a set interface and a get interface. The set interface is used to obtain the changed configuration data formed by the normal operation of the activated target software. The set interface obtains the change configuration data formed by the normal operation of the target software in the plaintext mode of Map<String, String>, and then calculates the ciphertext through an encryption algorithm.

Step S22: Encrypt the changed configuration data to obtain the encrypted changed configuration data.

Step S23: Use the encrypted changed configuration data to update the encrypted original configuration data pre-stored in the target database and the backup file list to obtain the updated configuration data; wherein, the encrypted original configuration data is for the activation of the original configuration data using the activation code. The original configuration data obtained after the target software is encrypted, and the encrypted original configuration data in the backup file list is the encrypted original configuration data stored in the backup file list in advance according to the slice storage method Data, and the total number of file addresses in the backup file list is greater than the number of file fragments corresponding to the encrypted original configuration data.

Step S24: Use the get interface in the preset system to read the encrypted original configuration data from the target database and the backup file list respectively, and decrypt it, and obtain the first decrypted data and the second decrypted data correspondingly. Decrypt the data.

Step S25: Compare 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. The get interface is used to read the updated configuration data from the target database and the backup file list respectively, and decrypt it, and correspondingly obtain the first decrypted data and the second decrypted data. The first decrypted data and the second encrypted data are compared to determine whether the first decrypted data and the second decrypted data are the same, so as to determine all the items in the target database or the backup file list. Whether the configuration data is illegally modified after encryption.

Step S26: If the first decrypted data is not the same as the second decrypted data, the target software is prohibited from being activated, and the target software is required to be reactivated.

Referring to FIG. 3, the 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: Use the activation code to activate the target software to obtain the original configuration data of the target software.

Step S32: Encrypt the original configuration data to obtain the original configuration data after encryption.

In this embodiment, it is necessary to obtain the original configuration data after the target software is activated by the activation code, and encrypt the original configuration data to obtain the encrypted original configuration data. Wherein, the activation code is generated by the operator of the target software using an activation code generation system. The activation code generation system is used to generate an activation code. Specifically, the operator of the target software generates a serial number only for this user according to the user's purchase order, and then uses the activation code generation system to combine the serial number with the machine on which the target software is installed The code generates an activation code. 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. Different data are separated by English commas. After obtaining the activation code, the target software uses the preset system to decrypt the activation code, and determines whether the activation code has expired according to the activation code expiration time, and if the activation code has expired, Then the target software cannot be activated, and if the activation code is not invalid, the target software is activated. When the activation code expiration time is given by a specific year, month, and day, the preset system reads the motherboard time of the machine where the target software is installed to determine whether the activation code has expired; when the activation code has expired When the time is given by the effective duration, the preset system determines whether the effective duration is 0 to determine whether the activation code has expired.

In this embodiment, after activating the target software, the preset system obtains the original configuration data, and encrypts the original configuration data to obtain the encrypted original configuration data.

Step S33: Store the encrypted original configuration data in the target database.

It is understandable that after obtaining the encrypted original configuration data, the preset system will also save the encrypted original configuration data in the target database.

Step S34: Use the random number to determine the target file address for storing the encrypted original configuration data from the backup file list.

In this embodiment, in the process of storing the encrypted original configuration data in the target database, the encrypted original configuration data is also stored in a backup file list in pieces. The step of using the random number to determine the target file address for storing the encrypted original configuration data from the backup file list includes: using the random number and a preset formula to determine the address for storing the encrypted The number of target file addresses of the original configuration data; determine a corresponding number of target file addresses from the backup file list to store the encrypted original configuration data; wherein, the preset formula is n=M%N , N represents the number of the target addresses, M represents the random number, N represents the total number of file addresses in the backup file list, and% represents the remainder operation. Wherein, the N file addresses in the backup file list need to be numbered in sequence, and the numbers are in sequence from 0 to N-1. Correspondingly, the determination of a corresponding number of target file addresses from the backup file list to store the encrypted original configuration data can be specifically understood as taking the nth file address among the N file addresses The first n file addresses are determined as the target file addresses. If the number of file addresses from the nth file address to the N-1th file address is less than n, then after the N-1th file address, start from the 0th file The address starts. For example, if the random number is 100005, and the total number of file addresses in the backup file list is 20, then 100005% 20=5, then there are 5 target file addresses for storing the encrypted original configuration data, which are sequentially The 5th, 6th, 7th, 8th and 9th file addresses. The random number is 100012, and the total number of file addresses in the backup file list is 20, then 100012%20=12, then there are 12 target file addresses used to store the encrypted original configuration data, which are the 12th in order. , 13, 14, 15, 16, 17, 18, 19, 0, 1, 2, and 3 file addresses.

Step S35: According to the number of the target file addresses, the encrypted original configuration data is divided into a corresponding number of fragments, and the fragments are sequentially stored in the target file addresses.

It is understandable that after the target file address for saving 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 includes: using an even distribution method to divide the encrypted original configuration data into a corresponding number of segments. If the length of the original configuration data after encryption cannot be evenly distributed into a corresponding number of segments, the length of the last segment is determined according to actual conditions. For example, if the length of the original configuration data after encryption is 120 bits, and the number of target file addresses obtained from the random number is 5, then the original configuration data after encryption is divided into 5 fragments, and the length of each fragment is 24. Bit. The length of the original configuration data after encryption is 119 bits, and the number of target file addresses obtained from the random number is 5. Then the original configuration data after encryption is divided into 5 fragments. The length is 24 bits, and the length of the fifth segment is 23 bits. Correspondingly, the segments are stored in the fifth, sixth, seventh, eighth, and ninth file addresses in sequence.

Step S36: Obtain the changed configuration data formed by the normal operation of the target software after activation.

Step S37: Encrypt the changed configuration data to obtain the encrypted changed configuration data.

Step S38: Utilize the encrypted changed configuration data to update the encrypted original configuration data pre-stored in the target database and the backup file list to obtain the updated configuration data; wherein, the encrypted original configuration data is for the activation of the original configuration data using the activation code. The original configuration data obtained after the target software is encrypted, and the encrypted original configuration data in the backup file list is the encrypted original configuration data stored in the backup file list in advance according to the slice storage method Data, and the total number of file addresses in the backup file list is greater than the number of file fragments corresponding to the encrypted original configuration data.

Step S39: Compare the first decrypted data corresponding to the updated configuration data in the target database with the second decrypted data corresponding to the updated configuration data in the backup file list, if the first decrypted data is If the decrypted data is different from the second decrypted data, the target software is prohibited from being activated, and the target software is required to be reactivated.

The application schematic diagram of the software anti-cracking method disclosed in this embodiment is shown in FIG. 4. The random number is obtained from the activation code, and the random number is used to obtain the remainder n to determine whether to store the encrypted The number of target file addresses and target file addresses of the original configuration data, and the encrypted original configuration data is stored in the target database and the target file address in the backup file list. Use the set interface in the preset system to obtain the change configuration data formed by the normal operation of the target software, and encrypt it to obtain the encrypted change configuration data. Use the encrypted change configuration data to update the target database and all the data. The encrypted original configuration data in the backup file list. Use the get interface in the preset system to read the updated configuration data in the target database and the backup file list respectively, and decrypt them, correspondingly obtain the first decrypted data and the second decrypted data, and compare them with each other. The first decrypted data and the second decrypted data, if the first decrypted data and the second decrypted data are not the same, the get interface controls the target software to disable activation, and requires the target to be reactivated Software; if the first decrypted data and the second decrypted data are the same, the get interface controls the normal operation of the target software.

Referring to FIG. 5, an embodiment of the present application discloses a software anti-cracking device, including:

The data acquisition module 11 is used to acquire the changed configuration data formed by the normal operation of the target software;

The encryption module 12 is used to encrypt the changed configuration data to obtain the encrypted changed configuration data;
