I work for a company that built an android app for another company. I joined a few months ago and the previous dev did not save the keystore file, nor do i have the necessary access to reset the key.

What we have is the following:

1. file without an ending(no .jks, or similar, just the file name which is the app name)
2. private_key.pepk file
3. upload_certificate.pem file

I am not well versed with keys/certificates etc. but from my research so far, there doesn’t seem to be a way to generate the actually jks i need for uploading an app update.

Of course, my boss does not want to tell the other company about the problem, as they will probably think that we are incompetent(which probably is true, if we can’t even store a key)..

I tried to find information on this problem on googles websites, but there doesn’t seem to be any documentation regarding this problem. The easy solution is probably to tell the other company that they need to reset the keystore and provide us with it, together with alias and key/password..
