Android – how to recreate the keystore file if it is accidentally deleted

This question has been answered here: > I lost my. Keystore file? I have a signed application and several keystore files. I want to update the application, so I need to find out which key is used

>If the keystore file is accidentally deleted, how to recreate it

I have restored it, but I want to generate the keystore file again

My question is simple:

How to convert. RSA files to. JKS

Please help

resolvent:

If you lose the keystore, it will disappear forever and you will not be able to do anything

If you have a keystore (if not, log in / pass, if not you may try bruteforce, log in / pass), then you can try to sign APK for each key and check the fingerprint matching version in Google play (you can "extract" the APK installed on the device). Please note that you can also use multi signature APK, but Google play only allows one signature, so it is not suitable for you

It's not enough to only have RSA signature (extract from the previously signed APK?) it's just the "public" part of the keystore, and everyone can extract it. You need the "private" part, which is only stored in the keystore

Keytool is a tool for playing keystore - generating keys, signing files, restoring "public" keys, etc., but in your case, it may not be useful. Just find this damn keystore... Good luck!
