loading the target binary data through the target glue code;
carrying out decryption operation on the target binary data to obtain non-encrypted binary data;
and compiling the non-encrypted binary data to obtain a first service code corresponding to the target installation-free application.
It can be seen that the electronic device described in the embodiment of the present application can obtain a target installation-free application on an installation-free platform, where the target installation-free application includes a target glue code and target binary data, the target binary data is encrypted data, and the target binary data is loaded through the target glue code; the method comprises the steps of carrying out decryption operation on target binary data to obtain unencrypted binary data, compiling the unencrypted binary data to obtain a first service code corresponding to a target installation-free application, calling the encrypted binary data through a glue code, and carrying out decryption and compilation to obtain a final service code.
Referring to fig. 1B, fig. 1B is a schematic flowchart of an application processing method according to an embodiment of the present application, and as shown in the drawing, the application processing method is applied to the electronic device shown in fig. 1A, and the application processing method includes:
101. and acquiring a target installation-free application at an installation-free platform, wherein the target installation-free application comprises a target glue code and target binary data, and the target binary data is encrypted data.
The installation-free application can be understood as an application that can be run when the website is started and that does not need to be installed, and the function corresponding to the application can be quickly implemented, for example, a game (H5 game/fast game, etc.), and the installation-free platform can be understood as a platform that can implement the operation of the installation-free application. The target installation-free application may be at least one of: the game application, the meal ordering application, the payment application, the office application, the mailbox application, and the like are not limited herein, and the installation-free platform may be a wechat platform, a paypal platform, a fast application platform, and the like, and is not limited herein.
In the programming arts, glue codes may also be referred to as adhesive codes, which may be used to adhere to codes that may be incompatible. For example, the glue code may be written in the same language as the code glued together, or in a separate glue language, which may not implement any functionality required by the program, which is typically present in code, enabling existing libraries or programs to interoperate in an external function interface (e.g., a Java native interface), which can be very efficient in a rapid prototyping environment, allowing several components to be quickly integrated into a single language or framework.
In this embodiment of the application, the electronic device may obtain the target installation-free application on the installation-free platform, the target installation-free application may include a target glue code and target binary data, the target binary data may be encrypted data, and a data mode of the target binary data may be at least one of the following: a symmetric encryption mode or an asymmetric encryption mode, wherein the symmetric encryption mode may be at least one of the following: DES, 3DES, TDEA, Blowfish, RC2, RC4, RC5, IDEA, SKIPJACK, AES, etc., and the asymmetric encryption mode can be as follows: RSA encryption, shift-first and xor-second encryption, etc., and the like, but are not limited thereto. The target glue code is used for realizing code reading loading or realizing pre-starting, for example, the target glue code may be responsible for driving the whole code to run, the target glue code may read binary data, integrate platform capabilities, and encrypt and compile an interface provided to the platform together, and the binary code may be used for realizing platform capability calling.
In one possible example, platform capabilities may be understood as business logic, the platform capabilities being at least one of: file capability, network capability, audio capability, video capability, drawing capability, each platform capability may correspond to a calling interface.
102. And loading the target binary data through the target glue code.
In the embodiment of the application, the electronic device can load the target binary data through the target glue code.
103. And carrying out decryption operation on the target binary data to obtain unencrypted binary data.
In specific implementation, because the target binary data is encrypted data, the probability that the target installation-free application is cracked can be reduced, the application safety is improved, and the copyright protection capability is favorably improved. Furthermore, the electronic device can perform decryption operation by adopting a decryption mode corresponding to the original encryption mode to obtain the binary data without encryption.
In a possible example, when the target binary data is encrypted by using a shift operation and then using an exclusive-or operation, the step 103 of decrypting the target binary data to obtain unencrypted binary data may include the following steps:
31. performing exclusive-or operation on the target binary data to obtain intermediate binary data;
32. and carrying out shift operation on the intermediate binary data to obtain the unencrypted binary data.
In the specific implementation, the target binary data is encrypted by the exclusive-or operation and then by the shift operation, so that the electronic equipment can perform the exclusive-or operation on the target binary data to obtain intermediate binary data, and the intermediate binary data is only the data encrypted by the shift operation and is subjected to the shift operation to obtain unencrypted binary data.
104. And compiling the non-encrypted binary data to obtain a first service code corresponding to the target installation-free application.
In specific implementation, the electronic device may obtain the first service code corresponding to the target installation-free application for the unencrypted binary data, and may further run the first service code. The compiling process may include two processes of compiling and linking, where a compiling part may be understood as converting a source file (code) into a binary language recognizable by a machine, and linking may be understood as combining a binary file generated by compiling into an executable file executable by a system, and these two parts are also called compiling as a whole. That is, a broad compilation is a conversion of code into an executable file. After compiling, the first service code can be run, so that the installation-free application can realize platform capability calling. Running is understood to mean the process of running a compiled executable file in a system, called running of a program.
Taking the game application as an example, because the business logic code of the game is not exposed in a plaintext mode any more, the code is prevented from being cracked and copied, and the difficulty of code understanding is increased; the logic of the code is not easily understood, reducing the possibility of game cheating.
In a possible example, in step 104, after compiling and running the binary data without encryption to obtain the first service code corresponding to the target installation-free application, the following steps may be further included:
a1, establishing a mapping relation between platform capability and a calling interface of binary data based on the first service code;
a2, acquiring a target calling interface corresponding to the unencrypted binary data;
a3, calling the target platform capability based on the target calling interface.
The first service code is realized based on an installation-free platform, and corresponds to the binary data without encryption, so that the first service code inevitably calls platform capacity to realize a series of operations, and thus, a mapping relation between the platform capacity and a calling interface of the binary data inevitably exists, and further, the electronic equipment can obtain a target calling interface corresponding to the binary data without encryption, and further, can call the target platform capacity based on the target calling interface.
In one possible example, before the installation-free platform acquires the target installation-free application in step 101, the following steps may be further included:
b1, acquiring a first business code corresponding to the target installation-free application, wherein the first business code is realized based on a first language supported by an engine in an application development engine tool;
b2, converting the first service code from the first language into a second service code realized based on a second language supported by the LLVM of the bottom layer virtual machine;
b3, compiling the second service code to obtain the unencrypted binary data and the target glue code;
b4, encrypting the binary data without encryption to obtain the target binary data;
b5, packaging the target binary data and the target glue code to obtain the target installation-free application.
In a specific implementation, before obtaining a target installation-free application, an electronic device may obtain a first service code corresponding to the target installation-free application, where the first service code is implemented based on a first language supported by an engine in an application development engine tool, and may convert the first service code from the first language into a second service code implemented based on a second language supported by a bottom level virtual machine (LLVM), where the first language is, for example, C #, and the second language is C + +, the first service code implemented by C # may be converted into the second service code implemented by C + +, and the second service code may be compiled to obtain unencrypted binary data and the target glue code, where the target glue code is used to implement read loading or pre-boot, and the second code may be used to implement platform capability invocation, and encrypting the non-encrypted binary data to obtain target binary data, and packaging the target binary data and the target glue code by a packaging tool to obtain the target installation-free application.
In a possible example, in a specific implementation, taking a game application as an example, the embodiment of the present application may be implemented based on a development platform and a user side, as shown in fig. 1C, specifically as follows:
aiming at the development platform side: includes the following steps S1-S3:
s1, the developer uses the language supported by the engine to write and develop the game business code in the game engine tool, for example: c #, Java, etc.;
s2, converting the game service logic code written by the engine development language directly or indirectly into the language of C + +, C and other common LLVM supporting compilation;
s3, compiling service logic codes written by languages supported by LLVM such as C + + and the like according to specified specifications to generate binary data and glue codes, encrypting the binary data, including shifting and the like, and performing confusion compression on the glue codes;
for the client side, the following steps S4-S5 are included:
s4, the generated glue code is responsible for reading and loading the encrypted binary data, and the read code content is sent to an installation-free platform;
and S5, the installation-free platform decrypts and compiles the binary data to obtain the binary code for running the game.
Among them, in steps S1 and S2, if the developer uses an interpreted language (Java, C #, etc.), the compilation tool (Mono, etc.) can compile it into a language supported by LLVM. If a language supported by the LLVM compilation tool is used (e.g., C, C + +, Rust, etc.), no further compilation may be required.
Further, in step S3, during the process of compiling the languages (C + +, C, etc.) supported by the LLVM into binary data, a glue code may be extracted, where the glue code may inject the basic capabilities (network, file system, audio, drawing, etc.) provided by the installation-free platform into the memory corresponding to the binary data for the binary code to call. At this point, the binary code may be intermodulated with platform capabilities during operation.
In step S4, the glue code may be responsible for driving the whole code to run, and the glue code may read the binary code data, integrate the platform capabilities, and perform encryption and compilation on the interface provided to the platform.
In step S5, the interface provided by the platform for running the binary data is called, and first, the binary data in the memory can be decrypted, mainly by performing decryption methods such as xor and shift, and the decrypted binary data is compiled, and the platform capability object is mapped in the memory with the address called by the binary data, so that the service logic code in the game can call the capability provided by the platform, and thus, the platform capability of the installation-free platform can be called by the installation-free application.
Further, as shown in fig. 1D, in this embodiment of the application, the installation-free platform may run the glue code by using platform capabilities, where the platform capabilities are as follows: the game service code can be used for intermodulation of platform capability and binary data.
In a possible example, between the step 101 and the step 102, the following steps may be further included:
c1, acquiring target identity information of the target object;
c2, verifying the target identity information;
c3, when the target identity information is successfully verified, executing the step of loading the target binary data by the target glue code.
Wherein, the target identity information may be at least one of the following: the fingerprint image, the iris image, the face image, the vein image, etc. may be stored in the electronic device in advance without limitation. In a specific implementation, the electronic device may obtain target identity information of the target object, match the target identity information with preset identity information, and when the target identity information and the preset identity information are successfully matched, determine that the target identity information is successfully verified, otherwise, determine that the target identity information is failed to be verified.
Further, when the preset identity information is the target face image and the preset identity information is the preset face image, in a possible example, the following steps may be further included between the above steps C1-C2:
