My understanding is no, it refuses to create keys in those directories. And later other ssh parts will refuse to use them. But I might be wrong. The author of ssh-host-config certainly believed that StrictMode was not necessary. -- R.

Is there perhaps a segmentation fault error? $ strace ssh-keygen I have a VM with Cygwin installed in it, which used to work for all the installed packages. However, after a recent update, all binaries linked to openssl now produce silent segmentation faults. Could be happening to you too. Best Regards, Dale CONFIDENTIALITY NOTICE

Use "chcp 65001" in your .bashrc or an equivalent file.
Many windows console tools will resort to English if they do not recognize
console code page. This includes netsh, netstat and ipconfig.
To make your life easier (i.e. not to type "chcp.com" every time), place a
script named something like "install-chcp-link.dash" in /etc/postinstall/ with
content along the lines of
> #!/bin/dash
>
> [ -f /usr/local/bin/chcp ] || {
> ln -fsT "$( cygpath -S )/chcp.com" /usr/local/bin/chcp
> }
>
> exit 0
and it will create a link on the next fill setup run.
