Lost the keystore and trying to update

So the keystore I originally uploaded my apk with seems to have disappeared off my computer I generated a new one but it threw an error:

You uploaded an APK that is signed with a different certificate to your previous APKs. You must use the same certificate. Your existing APKs are signed with the certificate(s) with fingerprint(s):

SHA1 lots of letters plus numbers

and the certificate(s) used to sign the APK you uploaded have fingerprint(s):

SHA1 lots of letters plus numbers

Is there a way I can regenerated the keystore and include these identifiers in it so I can update the app?

    If this is on Android, you are screwed. I ran into this problem 2 years ago. I havent found a fix, so had to start all over again. Your best bet is to search google/youtube as I havent looked for a long time.

    I actually had the original keystore but installed stuff on a new HD and it messed everything up. I would say contact Google Play but thats like talking to a brick wall

    Cryptographic keys are specifically designed to not be recoverable from the things they are used to sign, so if you can't find the original keystore you are probably out of luck. Even Google does not have the private key used to sign the apk.

    I backup my keystores on Windows and Mac to Dropbox. I recommend ANYONE publishing an app have multiple backups because it's a pain to try to restore them.
