> In the late 1990s, the Korea Internet & Security Agency developed its own 128-bit symmetric block cipher named SEED and used ActiveX to mount it in web browsers. This soon became a domestic standard, and the country's Financial Supervisory Service used the technology as a security screening standard. ActiveX spread rapidly in Korea. In 2000, export restrictions were lifted, allowing the use of full-strength SSL anywhere in the world. Most web browsers and national e-commerce systems adopted this technology, while Korea continued to use SEED and ActiveX.

I think the country only started moving away from SEED/ActiveX in 2011?!
