            SSL validation of HTTPS requests for the WinRM transport is disabled.
            HTTPS WinRM connections are still encrypted, but knife is not able
            to detect forged replies or spoofing attacks.

            To work around this issue you can use the flag `--winrm-no-verify-cert`
            or add an entry like this to your knife configuration file:

               # Verify all WinRM HTTPS connections
               knife[:winrm_no_verify_cert] = true

            You can also specify a ca_trust_file via --ca-trust-file,
            or the expected fingerprint of the target host's certificate
            via --winrm-ssl-peer-fingerprint.
