From https://palant.info/2023/01/02/south-koreas-online-security-... :
> I’ve heard about South Korea being very “special” every now and then. I cannot claim to fully understand the topic, but there is a whole Wikipedia article on it. Apparently, the root issue were the US export restrictions on strong cryptography in the 90ies. This prompted South Korea to develop their own cryptographic solutions.
> It seems that this started a fundamental distrust in security technologies coming out of the United States. So even when the export restrictions were lifted, South Korea continued adding their own security layers on top of SSL. All users had to install special applications just to use online banking.
> Originally, these applications used Microsoft’s proprietary ActiveX technology. This only worked in Internet Explorer and severely hindered adoption of other browsers in South Korea.
Wowsa!
