You can convert SHA-1 hash in hex format (as found in Play console) 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.
