Using SSL Certificates

This website uses a security protocol called SSL (Secure Socket Layer). SSL is the most popular security protocol on the Internet. The information that you can send on this website is encrypted by SSL, so it is hardly possible to understand the content even if you may see a third party on the way through the Internet. In addition, based on AKM's privacy policy, we consider it an important responsibility to protect the personal information of our customers.
It will not be used without your permission except for the purpose of contacting us. Since most major browser software is SSL-enabled, customers usually do not need to be particularly aware of SSL. When you enter a page that uses SSL, a lock mark is displayed at the bottom of the window (upper right if you are using a Mac). Browser addresses should begin with a string called https. If you are connected from a company or school network, this SSL may not pass depending on the firewall settings.
