Ah, very good. Does indeed sound like that.

Perhaps the originator (whom, after all, may be misrepresented by the
poster) has not designed security-by-obscurity, but simple obscurity-
by-obscurity, a perfectly valid and useful concept. But not what we
mean by cryptography.

Quand Maigret poussa la porte du Tabac Fontaine, vers une heure et demie,
le patron du bar, qui venait de se lever, descendait lentement un escalier
en colima çon qui s'amor çait dans l'arri ère-salle. ... Arriv é derri ère le
comptoir, il repousa le gar çon d'un geste n égligent de la main, saisit
une bouteille de vin blanc, un verre, m élangea au vin de l'eau min érale et,
la t ête renvers ée en arri ère, se gargarisa.  -- Simenon
