Interesting project

[startergo]

This is not an issue just wanted to get in touch. I need similar solution for packer.
The problem:
In this project after building the Vmware or Virtual Box images the script has to ssh to the machine and start performing actions inside. Apparently GO removed rsa/dss in the code so I am getting:

SSH handshake err: ssh: handshake failed: EOF

The server inside the Vmware macOS supports:

Is there a way I can use this project to make ssh communicating with a key?
