Moving to a 2048-bit certificate

New Standard for SSL Certificates Industry standards set by the Certification Authority/Browser (CA/B) Forum Baseline require that certificates issued after January 1, 2014 MUST be at least 2048-bit key length.¹

Why? As computer power increases, 1024-bit certificates are at risk of being compromised by hackers with sophisticated processing capabilities. The cybersecurity industry is moving to stronger 2048-bit encryption to help preserve internet security.

Action Required: What do I need to do?

If you have any 1024-bit certificates, you will need to migrate to 2048-bit key length by October 1, 2013*. Depending on when your certificate(s) expires, you'll need to take either of the actions below.

• New Certificates or Renewing before January 1, 2014 - use a 2048-bit Certificate Signing Request (CSR) when you buy a new certificate or during the renewal process
• Certificates that Expire after January 1, 2014 - you'll need to revoke your certificate and replace the certificate with a 2048-bit key length by October 1, 2013. It is FREE to replace a certificate and you'll still get all the time remaining on your current certificate.

Step-by-step Instructions

1. Do you have 1024-bit certificates?
   Use the SSL Certificate Checker (powered by Symantec) to check the key length of the CSR on your current SSL certificates.
2. Can your server handle a 2048-bit certificate?
   Longer key lengths require more server power and not all systems can handle a 2048-bit SSL certificate (if you're already running 2048 certificates, move on to step 3). You can easily test your system by requesting a Thawte test certificate with a 2048-bit key length. Get a test certificate. If you can't install the test certificate, contact our support team for help.
3. Generate your CSR
   
   • Microsoft IIS 6.0 or 7.0 running .NET 2.0 or higher or Red Hat Server - the SSL assistant will automatically generate your 2048-bit CSR and later install it.
   • All other servers or to manually generate a CSR - choose from a selection of step-by-step videos for CSR & Certificate Installation.
4. Log in to your account & choose your action




• Renew - certificates that expire December 31, 2013 and earlier with a 2048-bit key
• Revoke and Replace – All 1024-bit certificates that expire after January 1, 2014
