Some fetcher plugins (such as curl) might build upon OpenSSL to implement
HTTPS fetching. As we set (and can't unset) threading callbacks in our
openssl plugin, we must ensure that OpenSSL functions don't get called after
openssl plugin unloading.
We achieve that by loading curl and all other fetcher plugins after the base
crypto plugins, including openssl.
A connection between the hosts moon and sun is set up. The host moon
uses the Trusted Key Manager (TKM) and is the initiator of the transport
connection. The authentication is based on X.509 certificates.
