apk signer

Apk signer is an Android utility for self-checking the signature of applications and games downloaded to a mobile device. The smartphone owner can quickly find out if any changes have been made to the program source code. It is possible to export the necessary installation files and find out technical information about them.

Verification mode

Authentication of jar, zip and apk files is supported. The application allows you to commit any changes, which provides the ability to detect unofficial mods or a potential attack by malicious users. This problem is relevant because this scheme is often used for attacks on mobile devices. Malicious modules are introduced into popular programs, which can lead to unfortunate consequences. At the same time, the files look like original files and do not arouse suspicion, which allows for large-scale attacks. There is a built-in key manager that provides convenient import and export - you can send your own data set or download a third-party package. More experienced users can generate their own key files using the provided functionality. It is worth considering that the service may be unavailable in some countries, which will require the use of third-party tools to bypass blocking.

Tools

To scan signatures, after launching it is necessary to go to the tab with the list of all installed applications. A new scan is automatically initiated, and then the full list of installed programs is displayed in the format of a convenient table. System utilities are also added to the list. Detailed information is displayed for each entry, including version, original size and signature. It is possible to extract the installation file, which allows you to send it to another user for installation on another device. In this case, an exact copy of the program is created. To access the panel of creating a new key, you need to click on the icon with a plus sign. It is necessary to think up and specify a password, name, city and other data.
