You keep saying that but I disagree strongly. Having looked at both fnox and secretspec, there are some obvious similarities because they're both in the same space, interacting with many of the same tools, and there are only so many ways to declaratively state "set the FOO variable with the 'my_secret_key' value out of the Bar provider".

Those inherent similarities aside, I don't see it. They don't seem to have a lot in common as far as design or implementation or configuration.
