Vagrant is a tool for building and distributing development environments.

Vagrant::Util::SSH.check_key_permissions

Checks that the permissions for a private key are valid, and fixes
them if possible. SSH requires that permissions on the private key
are 0600 on POSIX based systems. This will make a best effort to
fix these permissions if they are not properly set.
