Am I Affected?

To check the key bit length of your SSL certificate, enter your domain name into the Comodo SSL analyzer at sslanalyzer.comodoca.com/. You need to look at the 'Key' row. If it states 2048 bit or higher, then you are OK.

What should I do to upgrade my 1024 bit SSL?

  • For certificates expiring on or before 31st December, make sure you generate a 2048 bit CSR when renewing your certificate
  • For 1024 bit certificates expiring after 31st December, please apply for a FREE 2048 bit replacement certificate. To do this, first generate a 2048 bit CSR for your domain then either:
    • Create a support ticket at support.comodo.com/index.php requesting a re-issue with reference to your order number. Refer to this support page for more guidance.
    • OR
    • If you have a 'Web Host Reseller' or 'EPKI' account, login to your account, locate your certificate order, click the 'Replace' link and complete the application form.
