Cryptolog was created in 1974 and was, according to the editor, “a new vehicle for the interchange of ideas on technical subjects.” Another editor called it “a mix of technical, expository, philosophical, futuristic, argumentative and historical articles – with a light touch here and there – there’s always an article or two to engage the reader.” Issues of Cryptolog were published initially on a monthly basis, but in the final years of its publication, were released on a quarterly basis. There were no issues published in 1993 and the final issue was released in July of 1997.

The Black Vault began not only archiving the released versions first put out in 2012, but later filing Mandatory Declassification Review (MDR) requests to get them further reviewed.

Below you will find the October 1981 edition, and the huge MDR request success that got much of it further declassified.
