The technique, yes, a general proof of perfect secrecy, no.

Up until the proof, at the earliest ca. (Shannon 1949 public, 1945 classified)
and (Kotelnikov 1941 classified), all they had was a hunch that something
magical was happening... a theory, but did not really know if it was snakeoil
or not until then. To the luck of earlier users, it turned out solid, though
improper usage still fell to things like VENONA.
