[0041] S104: decompress a first compressed file in the compressed file set into a file directory, wherein the first compressed file is a compressed file generated by a first compression algorithm.

[0042] The file directory includes but is not limited to: a decompressed file set corresponding to the first compressed file and a corresponding file list directory.

[0043] In one embodiment, after decompressing the first compressed file in the compressed file set into the file directory, the process includes: deleting the first compressed file in the compressed file set, thereby reducing the size of the application installation package and saving resources.

[0044] S106, compressing the file directory using a second compression algorithm to generate a second compressed file, wherein the compression rate of the second compression algorithm is greater than the compression rate of the first compression algorithm.

The file directory is compressed by the second compression algorithm to generate a second compressed file, which can reduce the size of the application installation package.

[0046] In one embodiment, it is determined whether the compression rate of the second compression algorithm is greater than the compression rate of the first compression algorithm. If so, the file directory is compressed using the second compression algorithm to generate a second compressed file; otherwise, the file directory is not compressed using the second compression algorithm to generate a second compressed file, and the first compressed file corresponding to the first compression algorithm is stored in the application installation package.

[0047] In one embodiment, the file directory is compressed by a second compression algorithm, and after the second compressed file is generated, the following steps are included: deleting the decompressed file corresponding to the first compressed file in the file directory, which can reduce the size of the application installation package and save resources.

[0049] In one embodiment, the decompression algorithm includes: a second decompression algorithm or a hybrid decompression algorithm, the hybrid decompression algorithm includes: a first decompression algorithm and a second decompression algorithm, the first decompression algorithm corresponds to the first compression algorithm; the second decompression algorithm corresponds to the second compression algorithm; for example, the first compression algorithm is a zip compression algorithm, and the corresponding first decompression algorithm is a zip decompression algorithm, the second compression algorithm is a 7Z compression algorithm, and the corresponding second decompression algorithm is a 7z decompression algorithm, and the hybrid decompression algorithm is a decompression algorithm in which the zip decompression algorithm and the 7z decompression algorithm coexist.

[0050] In one embodiment, the compression algorithm code and source code corresponding to the compressed file are automatically or manually modified, the decompression algorithm code is replaced, etc.

[0051] In one embodiment, the first decompression algorithm is replaced with the second decompression algorithm or the hybrid decompression algorithm manually or automatically.

[0055] In one embodiment, when a compressed file set corresponding to the application installation package during compilation is obtained, the second compressed file and the decompression algorithm are sent to the installation package directory; the installation package directory is packaged to generate an installation package file of the application.

[0056] In one embodiment, when the application installation package is decompressed to obtain a compressed file set corresponding to the application installation package, the second compressed file and the decompression algorithm are sent to the installation package directory; the installation package directory is recompressed by the second compression algorithm, and signed to obtain the application installation package file.

If the installation package file of the application is successfully decompressed by the second decompression algorithm, the installation package file of the application is judged to be in the second compression format. If the installation package file of the application is not successfully decompressed by the second decompression algorithm, the installation package file of the application is judged to be in the first compression format.

[0065] In the above embodiment, the compression and decompression algorithms of the SDK library without source code can be modified.

[0079] S304: When a compressed file set corresponding to the application installation package is obtained by decompressing the application installation package, the second compressed file and the decompression algorithm are sent to the installation package directory.

[0080] In one embodiment, all compressed files in a compressed file set corresponding to an application installation package are traversed, and after a first compressed file generated by a first compression algorithm in the compressed file set is decompressed into a file directory through a plug-in, the first compressed file in the compressed file set is deleted, and the file directory is compressed through a second compression algorithm to generate a second compressed file; for example, after a first compressed file in a zip format generated by a zip compression algorithm in the compressed file set is decompressed into a file directory through a plug-in, the first compressed file in the compressed file set is deleted, and the files in the file directory are compressed again through a 7z command corresponding to the 7z compression algorithm to generate a second compressed file in 7z format.

[0083] In one embodiment, the files in the installation package directory are traversed, and the message digest of the files is calculated and encoded, and then the message digest is encrypted using a private key to generate a digital signature, and the file and the corresponding digital signature are sent to the recipient.

[0084] In the above embodiment, based on the automation plug-in, the compression algorithm of the compressed files in the compiled application installation package is automatically modified, the first compression algorithm is automatically switched to the second compression algorithm in batches, and the second decompression algorithm or mixed algorithm code is automatically implanted to replace the original first decompression algorithm and encapsulated.
