Yesterday, I (with my X2Go upstream hat on) have added a new (long waited for) feature to PyHoca-GUI / Python X2Go.
So far, in PyHoca-GUI (python-x2go) it was only possible to use passphrase-protected / encrypted SSH keys via an ssh-agent process that unlocks those keys when being added to the agent's keyring previous to logging into an X2Go Server.
Unlocking those keys natively in PyHoca-GUI was not possible so far.
-> Now it is!!!
This feature will be available with PyHoca-GUI 0.4.0.9 / Python X2Go 0.4.0.9 (and PyHoca-CLI 0.4.0.3).
