According to the CIA, “one document outlines the chemicals and techniques necessary for developing certain types of secret writing ink and a method for opening sealed letters without detection. Another memorandum dated June 14, 1918 — written in French — reveals the formula used for German secret ink.”
The secrets can now be revealed, CIA Director Leon Panetta says in a statement, because “recent advancements in technology” apparently make the methods obsolete.
