The NSA’s “Fifty Years of Mathematical Cryptanalysis (1937–1987)”
published on 2025-05-19 11:06:23 UTC by Bruce SchneierContent:
In response to a FOIA request, the NSA released “Fifty Years of Mathematical Cryptanalysis (1937-1987),” by Glenn F. Stahly, with a lot of redactions.
Weirdly, this is the second time the NSA has declassified the document. John Young got a copy in 2019. This one has a few less redactions. And nothing that was provided in 2019 was redacted here.
If you find anything interesting in the document, please tell us about it in the comments.
