The public certificate (joint certificate) for using post office internet banking can be easily issued and used through the post office internet banking website. In the following, we will look at how to issue a post office public certificate.
Financial certificate and co-certificate
Financial certificate and co-certificate
Due to the implementation of the revision of the Digital Signature Act on December 10, 2020, additional financial certificates were introduced from the existing public certificates, and certificates were classified according to the purpose of use. A co-certificate refers to an accredited certificate that was previously used, and is recently called an “old accredited certificate”.
Certificate Classification
Joint certificate (formerly public certificate) Financial certificate
The difference between a financial certificate and a joint certificate is based on the purpose of use. Unlike public certificates used for authentication and transactions on the Internet, financial certificates can only be used in the financial services of the issuer. This certificate is available.
Recently, certificates that can be used universally, such as KB Kookmin Bank and Shinhan Bank, have been introduced, but in the case of financial certificates, the main purpose is to use them exclusively for financial business.

Certificate validity period
Then the financial certificate looks bad, but is it really?
Since financial certificates have a validity period of 3 years compared to joint certificates with a validity period of 1 year, there is no need to renew them every year. Because the certificate is stored in the financial institution’s cloud, it is a certificate that does not need to be carried separately or worry about security.
