The disclosure relates to security technologies and discloses a method, an apparatus and a client device for extracting signature information from application installation packages. The method comprises: decompressing data in an application installation package whose size is not greater than a threshold value (100); analyzing the decompressed data to obtain critical data that can be used to extract signature information of the application installation package (101); repeating the above two steps until the application installation package is completely decompressed to obtain all the critical data of the application installation package (102); and parsing all the critical data to extract signature information of the application installation package (103). The technical solutions can effectively reduce memory usage during extracting signature information from the application installation packages, thus improving the efficiency in extracting signature information from the application installation packages. |
