Quovadis: Insufficient Serial Number Entropy

RESOLVED INVALID DarkMatter LLC
AI Summary

The case concerns Quovadis, which identified an issue with insufficient serial number entropy in s/MIME certificates. The CA discovered that one of its hardware security modules (HSM) was using a default setting that did not meet the required entropy levels. Although all TLS certificates were compliant, 118 s/MIME certificates were issued with low entropy. The CA took corrective actions, including changing the entropy settings to meet the required standards. Ultimately, the issue was resolved, and the case was marked as invalid after confirming compliance with Mozilla's policies.
