As keyring maintainers, we no longer consider 1024D keys to be
trustable. We are not yet mass-removing them, because we don't want to
hamper the project's work, but we definitively will start being more
aggressively deprecating their use. 1024D keys should be seen as
brute-force vulnerable nowadays. Please do migrate away from them into
stronger keys (4096R recommended) as soon as possible.
