Yeah, you need the .keystore file and key store password, and I think you need to use also the same key alias and key password but I'm not sure.
The keystore file should be property of the publisher of the app. But if you, as hiring company, didn't ask for it by contract, it can be difficult to convince the developer to give it to you. It is true that it's a digital signature, but there are only two reasons I can think why they could want to keep it: 1. to have a leverage to ask you for more money 2. they used the same keystore on all their projects, and they're afraid of the security issues it could rise if you use the same keystore to publish tampered versions of their other apps outside Play Store In the first case, brace yourself for a nice ride. In the second case, I guess you need to convince the developer that you're not dangerous.
