The certificates that the cloud client will respect when verifying remote host
certificates are in the "lib/certs" directory of the cloud client.

As of cloud client 16 (which is only in RC2 state right now), you can override
that using the NIMBUS_X509_TRUSTED_CERTS environment variable to point at
another directory.

The "6045a439" you are seeing is an advisory message only.  This is something
you could override in the cloud.properties file you distribute to your users
(putting e.g. "vws.cahash=01abcdef" in it).

Docs for extra properties were here before 2.5:

And here now:
