android - Google play app signing key hash

Question

I have opted for google play app signing and i understand that google changes the signing keys for the app and I found the Sha 1 certificate but couldnt find the keyhash .

How can i get the keyhash of my released app is there a way to extract it from the certificate?

Answer 1

You can convert SHA-1 hash in hex format (as found in Play console, see Release management -> App Signing) into base64 hash using next command:

echo 33:4E:48:84:19:50:3A:1F:63:A6:0F:F6:A1:C2:31:E5:01:38:55:2E | xxd -r -p | openssl base64

Output:

M05IhBlQOh9jpg/2ocIx5QE4VS4=

This hash can be used for example when setting up Facebook app.
