June 16, 2026 by Stephen DavidsonBallot SMC017v2: Increase Minimum RSA CA Key SizeSummary: This ballot increases the minimum RSA key size for Root and Subordinate CA certificates in the S/MIME BRs from 2048 to 4096 bits for keys created after September 15, 2026, while retaining the 2048-bit minimum for Subscriber certificates.
