DigiCert: Use of forbidden subjectPublicKeyInfo algorithm

RESOLVED DigiCert
AI Summary

DigiCert faced issues related to the use of the forbidden P-521 algorithm in certificates issued after the effective date of policy 2.4. The CA was prompted to provide an incident report and took steps to block issuance of these certificates. The resolution involved patching the CA to prevent the use of P-521 for publicly trusted certificates, and DigiCert has since implemented a compliance team to monitor policy changes more effectively.
