Running crypt4gh-keygen results in an error when ~/.c4gh does not exist

[RichardJActon]

Whilst it is reasonably simple to infer from this error (see below) that making the ~/.c4gh directory before running this command again would likely remedy the issue, (it does), it appears to be an unhandled error and it would likely be better UX to simply create this directory if it does not yet exist.

Yep, you're right.
And like the .ssh directory, it should have permissions 700, and a message that the directory was created.
Thanks for reporting it.
