What's changing?

The CABF, a consortium of certification authorities and web browsers, has recently drafted and approved the Baseline Requirements for the issuance of Publicly Trusted S/MIME certificates to reinforce the security of email encryption and digital signatures, effective September 1, 2023. These changes will ensure strong encryption algorithms, secure key lengths, and reliable certificate validation procedures.

  • Purchase: August 14, 2023 is the last day you can purchase or renew your Class-2 S/MIME certificates under existing standards.
  • Order Submission: For Class-2 S/MIME certificates that have been purchased or renewed under existing standards, August 21, 2023  is the last day for order submission.
  • Validation: any orders not validated by August 28, 2023, will be cancelled.
