I'm writing code to create automatically datacenter/cluster/host, without storing the root password in scripts. Having a way to have the sdk automatically get it would be nice. Having a known URL is good enough, but it it's not obvious to find it.

The resource is missing content-disposition, and the date is not optimal:

$ curl -JORLkv 'https://XXXX/ovirt-engine/services/pki-resource?format=OPENSSH-PUBKEY&resource=engine-certificate'
< HTTP/1.1 200 OK
< Date: Wed, 09 Aug 2017 14:22:49 GMT
< Server: Apache
< Set-Cookie: locale=en_US; path=/; HttpOnly; Max-Age=2147483647; Expires=Mon, 27-Aug-2085 17:36:56 GMT
< Content-Type: text/plain; charset=ISO-8859-1
< Content-Length: 394

$ls 
...
pki-resource\?format\=OPENSSH-PUBKEY\&resource\=engine-certificate 

See curl(1)

       -J, --remote-header-name
              (HTTP)  This  option tells the -O, --remote-name option to use the server-specified Content-Disposition filename instead of extracting a
              filename from the URL.

              If the server specifies a file name and a file with that name already exists in the current working directory it will not be overwritten
              and an error will occur. If the server doesn't specify a file name then this option has no effect.

              There's  no  attempt  to  decode %-sequences (yet) in the provided file name, so this option may provide you with rather unexpected file
              names.

              WARNING: Exercise judicious use of this option, especially on Windows. A rogue server could send you the name of a  DLL  or  other  file
              that could possibly be loaded automatically by Windows or some third party software.
