Notification to the impact of upgrading hash algorithm for SSL certificate on our web services
2 Mar 2015
In order to enhance the security of our web services, we will soon upgrade our SSL certificates for MyPage site and Web Service Portal site on our home page.
Technically, hash algorithm of SSL certificates will be changed from "SHA-1" to "SHA-2", and it would affect Windows XP users. (Windows XP, except for Windows XP Service Pack 3, cannot be used for these web services.)
We are sorry for the inconvenience, but your kind understanding would be much appreciated.
If you have any inquiry on this matter, please feel free to contact us.
