Upgrade your SSL certificate to 2048 bits before Dec. 31st – Free

December 5, 2013 | By Kevin Judge

SSL CertificateWith the continued evolution of modern day super-computers and processing power, there exists the chance, albeit remote, that hackers could acquire the raw processing power to brute force 1024 bit RSA keys within the next 20 years. As a preemptive measure against this possibility, the National Institute of Standards (NIST) and Certificate Authority/Browser (CA/B) forum has mandated that all SSL certificates must have a minimum key length of 2048 bits from 1st January 2014. Comodo advises all our customers to check the key length of their SSL Certificate and takes steps to replace it if required.

How do I discover the key size on my certificate?

The fastest way to do this is to enter your domain in the Comodo SSL analyzer at sslanalyzer.comodoca.com/. You need to check out the ‘Key’ row. If it states 2048, you are safe. If it is a number lower than 2048 bit (for example 1024), then you need to upgrade before Dec 31st 2013.

How do I upgrade my 1024 bit SSL?

  • Certificates expiring on or before 31st December must be renewed with a 2048 bit certificate signing request (CSR)
  • Certificates expiring after 31st December can be replaced for FREE up to the validity period of the original certificate. To do this, you must first generate a new 2048 bit CSR on using your web-server software with the same details as your current certificate. Next,
  • Login at support.comodo.com and create a support ticket requesting that your certificate is replaced with a 2048 bit certificate. Please remember to mention your order number, domain name, web-server software and to attach your 2048 bit CSR to the ticket.
  • OR
  • If you have an EPKI or web host reseller account then login, locate the certificate order in question and click the ‘Replace’ link. This will open an order form which will allow you to submit your updated CSR.

    Wow! People don’t have much time if they need to upgrade.
    Does anyone know what will happen to them on January 1st?

    It will depend on whether the browser vendors update their root certificates to remove 1024bit certs. When they do, when a user goes to a site with 1024 bit they will not be able to establish a secured connection.
