Answer 1

Instetad of SHA1, type SHA. You will get 28 char long hashcode for fb. I was having the same issue, but this way I could resolved.

Answer 2

I'm using Windows Powershell and it is generating a 24-length key. Switched back to old cmd. Thanks to this answer: https://stackoverflow.com/a/41677624/9376804
