  26 // acl_protectedpw - protected-path password-based ACL subject types.
  27 //
  28 // This implements "protected path" password-based subject types as per CSSM standard.
  29 // A "protected path" is something that is outside the scope of the computer proper,
  30 // like e.g. a PINpad directly attached to a smartcard token.
  31 // Note: A password prompted through securityd/SecurityAgent is a "prompted password",
  32 // not a "protected password". See acl_prompted.h.
  33 //
  34 // @@@ Warning: This is not quite implemented.
