I am currently working on an app that I didn't create and need to create a new release apk. I have a .dat file that is supposed to contain a certificate of some sort, but I have no idea how to use it or what the file contains.
I've tried using keytool to treat it as a certificate and import it into a keystore, but I get an error: keytool error: java.lang.Exception: Input not an X.509 certificate
openssl doesn't recognize it no matter what I try.
Is there something I can do to figure out what this .dat file is? I'm somewhat new to android development and have only used .jks files to store my keys.
