//
// acl_protectedpw - protected-path password-based ACL subject types.
//
// This implements "protected path" password-based subject types as per CSSM standard.
// A "protected path" is something that is outside the scope of the computer proper,
// like e.g. a PINpad directly attached to a smartcard token.
// Note: A password prompted through securityd/SecurityAgent is a "prompted password",
// not a "protected password". See acl_prompted.h.
//
// @@@ Warning: This is not quite implemented.
