[Peter Saint-Andre <stpeter AT jabber.org>]

Never mind, Jer straightened me out. So I did:

1. echo -n 'xmpp:stpeter AT jabber.org' | openssl dgst -sha1

afa6353518f818af2f036da336c3097dedc00dee

2. echo -n 'https://www.xmpp.net/' | openssl dgst -sha1

3115de01ebfa34a34314060b5f30038b0fa359f8

3. echo -n 
'afa6353518f818af2f036da336c3097dedc00dee3115de01ebfa34a34314060b5f30038b0fa359f8' 
| openssl dgst -sha1

6196ea6709be2a4cbdf2bc0cfaeac491f2fb8921

Which matches Eran's output.
