Struct AppCheckerSha256 

pub struct AppCheckerSha256 { /* private fields */ }

A Credentials Checking Policy that only runs Userspace Binaries which have a unique SHA256 credential.

A Userspace Binary without a SHA256 credential fails checking, and only one Userspace Binary with a particular SHA256 hash runs at any time.
