Securing (SSL) WINRM connection to remote servers

Honolulu uses WinRM via TCP/5985 to connect to remote servers. Only to my knowledge WinRM via TCP/5985 by default is not encrypted. How can we use Project Honolulu with WinRM via HTTPS (TCP/5986)?

    Actually, WinRM over HTTP is encrypted if you don't use Basic or Digest authentication.

    The communication is still encrypted, but you can't verify server identity. A hacker can steal NTLM hash and crack it.

     

    Everything is good if your machines are in domain. Kerberos is used in this case.

    Stupidest limitation ever! In our Enterprise we only use WinRM HTTPS TCP/5986 as you should be doing for Infrastructure mgmt.... I was really looking forward to using this, but it's so slow between clicks & this is definately a showstopper. 1st I had to allow it to talk to the internet due to signature verification 1x even though it's touted as being offline ready & now this...
