: Until 1996, the U.S. classified encryption software as a "munition," placing strict limits on exporting strong code (typically anything above 40-bit keys).
: The Clipper Chip failed due to public outcry and a critical security vulnerability discovered by researcher Matt Blaze in 1994. By 1999, the U.S. removed most retail export restrictions. 2. Phase 2: The Device & Messaging Era (2010s–2020s) Crypto Wars
: Programmer Phil Zimmermann was investigated for "arms trafficking" after his Pretty Good Privacy (PGP) software was distributed internationally. : Until 1996, the U
: The Clinton administration proposed the Clipper Chip , a microchip for phones that would use a "key escrow" system to give the government a "backdoor" to communications. By 1999, the U
The first iteration, often called , centered on the U.S. government's attempt to control cryptography as a military asset.
The "Crypto Wars" refer to the multi-decade political and legal conflict between governments (primarily the U.S.) and the technology community regarding the use of strong encryption. Governments argue that unbreakable encryption hinders law enforcement's ability to investigate crime ("going dark"), while technologists and privacy advocates maintain that encryption is essential for digital security and civil liberties. 1.
