You want to see what you can find out about it: unzip -p suspect. RSA keytool -printcert That's going to dump out a lot of information about who the signer claims to be. Some certificates are apparently themselves signed by known parties, but without figuring out how to trace that, I suspect you could do something like this: unzip -p suspect.
RSA keytool -printcert grep MD5 unzip -p knowngood. RSA keytool -printcert grep MD5 If you have a known trusted apk from the same author who used the same certificate.

Then one can check the certs as you said. In addition, you can extract an APK from a device with the following application: play.
Recent Android Apps often do no longer contain a v1 signature that can be verified with jarsigner only a v2 orand v3 signature. The correct way to verify an APK file is to use apksigner. Robert Robert This is the answer that helped the most, thanks! I used apksigner to compare the cert from an app from the same developer I got from the Google App Store and the one I got from ApkMirror — yorch. BorislavIvanov You should mention that your Link is Windows only.
Check the section "Command line tools only" here: developer. In total you end up with about MB download. From the docs : Check whether the APK's signatures are expected to be confirmed as valid on all Android platforms that the APK supports: apksigner verify [options] app-name.
Dan Hulme Community Bot 1. I wouldn't trust the virus check, as doubt that these anti-virus programs focus on just every Android APK ever distributed.
Also, the MD5 will not tell you much, apart from that the same file has been uploaded before. Stan - It scans the bytes in the file for malware bytes. It doesn't have to know every APK ever distributed.
Also, it's not an MD5, it's a SHA and there is a bit of additional info communicated in that if this is the first time the APK has ever been uploaded then maybe it is something unknown and more possibly malicious. Also, most valid APKs will probably be there. Why not include this as part of analysis as another tool for use? It can provide just another level of confidence or non-confidence about the package. You don't have to consider it the final word, but considering it more data — raddevus.
OK I agree it's useful as an additional source, just not the only one. Nozalys Nozalys 1. Sign up or log in Sign up using Google.

Checking Integrity of a file Checking the integrity or hash value of a file is aims at checking that either a file is genuine or verifying that a file has not been modified by untrusted parties.
How to check the hash value? Figure 1: MD5 Value Along with a File MD5 or SHA family hashes are set of random strings that allow security professionals to make sure that the downloading file is not tampered with or not corrupted.
SHA hash checker command Windows MD5 checksum command line Windows Just open a command prompt and execute the following command to check the MD5 hash checksum of a file:. To find out the SHA checksum, you just need to replace the MD5 parameter in the above command with some other hash algorithm. If you are a Mac user, you can use terminal commands to check the hash value or MD5 checksum of a file. Thus, you can easily get the MD5 checksum on Mac.
Do you know all the possible ways to capture the screen of your Mac? Here are 3 methods to take screenshots on macOS. Just launch the Terminal window and execute the following command to go to the directory where the file is located.
In case you have Ubuntu, you can use this command:. If you want to generate or verify the checksums of various algorithms via GUI graphical user interface , you can use a tool called GtkHash. Download GtkHash from Github and install it using the following command:. When GtkHash is installed, launch the app and add the file by clicking the Browse icon in the File section. If you want to match the checksum of the original file with your downloaded copy, paste the original hash value in the Check field and click the Hash button.
In case you decide to uninstall this app later, head over to our tutorial on uninstalling apps on Ubuntu. Moreover, you should also check out these 20 useful commands for Ubuntu to make the most of your computer.
QuickHash is not only very easy to use but also offers more features than most other hash checkers and generators. However, it supports only a few popular hash algorithms. QuickHash can check hash code or MD5 checksum for a single file, multiple files, or all files in an entire folder or disk. If you want to compare the hash codes or MD5 checksums of 2 files or folders, QuickHash can help you with that too.
Suppose you want to compare MD5 checksum of two files in QuickHash, you just need to click the Compare Two Files tab, add both the files and click the Compare Now button. Not just that, QuickHash can also generate the checksum or hash value for all supported types.
