Hongkong Post e-Cert CA 1 - 10 issuing certificates without subject alternative name extension

RESOLVED Government of Hong Kong (SAR), Hongkong Post, Certizen
AI Summary

The Hongkong Post e-Cert CA 1 - 10 was found to be issuing certificates that lacked the required subject alternative name (SAN) extension, which is a violation of best practices. Although the CA ceased issuing SSL certificates using SHA-1 as of January 1, 2016, issues persisted with the certificates being issued. The case was resolved after the problematic certificates were added to OneCRL, ensuring compliance with the CA/Browser Forum's Baseline Requirements.
