History

Historical Context

The 1991 release of Phil Zimmermann’s PGP sparked the first public challenge to U.S. cryptography export bans, prompting industry pressure that led President Bill Clinton to sign Executive Order 13026 in 1996. A 1999 revision of the Export Administration Regulations then permitted 56-bit encryption and 1024-bit RSA to be exported without backdoors, setting a precedent used today for AI model licensing.
