-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 At the very first connection established with the XMPP server, Poezio XMPP client displays a window to accept or reject the server's certificate. It prints the sha256sum of the public key of the server (not in the certificate itself, but provided by the server too). On the server, I run the command: $ openssl pkey -in file.key -pubout -outform DER | openssl dgst -sha256 -hex -c | awk '{ print toupper ($2) }' Result on jabber1.casperlefantom.net: 4B:A8:16:05:E4:B4:5C:A9:66:42:E2:99:71:72:F5:07:CB:2E:10:30:CD:F9:DC:78:99:E6:85:6B:74:8A:EF:8A Result on jabber2.casperlefantom.net: 22:91:37:56:B8:45:6A:4E:8A:34:CD:1C:0C:ED:26:5F:63:72:36:B0:A8:C9:4A:46:9D:8E:20:1B:B8:37:37:95 The client should display the same thing. If you edit the config file directly, keep in mind it is case sensitive. The purpose of this file is to make client-server connection check, at any time. It will be updated when server's certificate will change.
