SSH key generation error in docs

[cognitivegears]

Describe the Bug
The ssh key generation documentation has gotten a little out of date. ssh-keygen no longer defaults to outputting RSA, but our version of ssh2 doesn't support newer algorithms. Also, the docs in config.hjson is even older and also needs updating. We should update the docs and look at updating ssh2 as well.

To Reproduce
Follow the docs to run ssh-keygen.

Expected Behavior
Enigma starts normally.

Is there a quick fix for this by way of a parameter passed to openssl?

Yes - you can just pass -t rsa to openssl to generate a RSA key.

[cognitivegears]

The documentation has been updated, as well as an update to the ssh2 library in PR #515. The updated ssh2 does support ECDSA, however we still don't want to use it (in most cases) because some old ssh clients like Netrunner don't like it still.

Closing this issue as completed.
