CA Root Upgrade for GeoTrust Certificates

Posted by software store on Wednesday, March 10, 2010 in Blog.

GeoTrust has alerted the ITS Software Store that it will upgrade its public root certificate authorities (CAs) in a few months. After this change takes effect, all SSL certificates purchased by Vanderbilt departments through the Software Store will be signed from the upgraded CA structure and hierarchy.

The upgrade will increase the RSA key length, and related strength, of each CA from 1024-bit to 2048-bit. Certificates from the new CAs will be issued from intermediate roots, creating a stronger, chained CA hierarchy.

• Existing valid certificates issued off of current 1024-bit RSA keys will continue to operate correctly and securely after the migration to the 2048-bit RSA keys.

• No action is required on the part of customers.
