+== Annex: building openssl for Debian Jessie
+
+The OHCredentials service needs OpenSSL 1.1 but Debian Jessie only has
+1.0. The following recipee builds a static version of the openssl command,
+which is installed with a specific name (upmpdcli-openssl). No libraries
+are installed and the standard command is left undisturbed, so that there
+is no risk of damaging the system.
+
+Note that I am making no claims about the security of the encryption
+provided by this method. This should be fairly sufficient for a Qobuz
+password going around your local network though (except maybe if you think
+that the NSA is interested in your playlists).

+
+
+Then edit '/etc/upmpdcli.conf' and add the following:
+
+ opensslcmd = /usr/bin/upmpdcli-openssl
+
+We chose to copy the command to '/usr/bin', but this could be any
+place. Change the path in '/etc/upmpdcli.conf' in this case.
+
+Restart upmpdcli, and the logins from Kazoo should work.
