eMudhra emSign PKI Services: Policy Document Inconsistency
eMudhra Technologies Limited issued a TLS certificate for CN=msmeranchi.nic.in with an RSA key size of 4048 bits, which was compliant with Baseline Requirements but inconsistent with their published Certificate Policy (CP) and Certification Practice Statement (CPS) that only referenced RSA 2048. This discrepancy was identified by an external researcher on June 19, 2025, leading to a review and subsequent updates to the CP/CPS to clarify acceptable key sizes. The incident was resolved by revoking 449 unexpired certificates that did not align with the clarified policy, and the updated CP/CPS was published on July 8, 2025.
