This receiver from Watkins-Johnson played an important role in the Watergate Scandal (1972-1974) that eventually led to the resignation of US President Nixon in 1974. www.cryptomuseum.com/df/wj/rs111/

Sometimes I can see how the mechanism works from the scans, but in complex cases, it can be best to just model it and see what happens. The rotor stepping of the SG-41 mechanism is in the second type! The answer is mind-blowing! @tnmoc.bsky.social @threejs.org @cryptomuseum.bsky.social

This device was used by the German Army to capture and decode Yugoslav telegraphy signals in Kosovo: www.cryptomuseum.com/telex/rs/ga0...

Check out this power supply unit of 1965. It was used with the Fialka cipher machine (M-125) and proves that the Russians were well aware of TEMPEST and side-channel attacks. www.cryptomuseum.com/crypto/fialk...

A deeper look at recent claims by Chinese media of a “real and substantial” quantum computing “breakthrough” to attack SPNs, the underlying algorithms of modern cryptography including AES. Via @dangoodin.bsky.social. TL;DR: Turns out, the death of modern cryptography is greatly exaggerated.

"Chinese scientists reveal D-Wave’s quantum computers can break RSA encryption, signaling an urgent need for new cryptography solutions." 😮 www.thebrighterside.news/post/for-the....

Just a quick message to let you all know that @cryptomuseum is now also active on Bluesky. Crypto Museum is a non-profit virtual museum for everyone interested in the history and technology of cryptography (such as Enigma), spy radio, covert devices and much more. Visit us at www.cryptomuseum.com
