HARICA: P-384,ecdsa-with-SHA256 Certificates
HARICA identified a compliance issue where it had issued Intermediate CA Certificates using ECDSA P-384 keys with SHA256 hashing, violating Mozilla's Root Store Policy. This was discovered during a policy review on February 25, 2019. Following the identification, HARICA disabled certificate issuance from the affected subCAs and conducted a database scan, revealing one affected end-entity certificate and five intermediate CA certificates. The problematic certificates were planned for revocation by March 8, 2019, and mitigation measures were implemented to prevent recurrence. The issue has since been resolved.
- Compliance issue discovered during policy review.
