I already have that info and the SHA-1 signature is the same as I had during creation the key.

No certificate that when you create a key in C3 and signature .*aab does not fit. Google uses it as a download key certificate.
You need to take the one in the developer's console. There when you distribute through the playmarket google signs the packages again.
Go to console->select your application->settings menu->application integrity->there is a tab "application signatures"
