Obtaining Digital Certificates

The instructions in this document are specific to SSL certificates. For other types, contact the Digital Certificates Manager

certificate-request (at) iastate (dot) edu
for more information. Note that the certificate request instructions below depend on the Thawte website, which may change. Should you have questions, please contact the Digital Certificates Manager.

Information Technology Services (ITS) has an account with Thawte under which Digital Server Certificates can be obtained. The cost for a new SSL certificate is $149.40. Renewal SSL certificates are $99.50. (ITS assesses no processing charge. The amounts are Thawte's charge for certificates.) The process of obtaining a certificate under this contract is somewhat simpler than the process required to set up your own account with a certificate supplier.

Before you can request a certificate at the Thawte website, you must have a Thawte user ID. Go to http://www.thawte.com/ and sign up for a "free personal e-mail certificate" under the Products menu. This will establish a Thawte ID for you. You will need to send that ID to

certificate-request (at) iastate (dot) edu
(As manager of the Iowa State University account, the Digital Certificates Manager must authorize your Thawte ID before you can proceed.) The subject line of your message should say "Thawte Certificate Request". In the message, along with the ID, you should identify the machine for which you will be making a request.

To obtain a certificate under the Iowa State University account, please send an intramural purchase order for either $149.40 for a new certificate or $99.50 for a renewal to IT Services, 271 Durham Center, Attn: Bill Frazier. The item description for the intramural should be "Digital Certificate for <the-name-of-your-server>". If you wish to FAX the intramural, it should be addressed to Bill Frazier at 515-294-1717.

After submitting the intramural, you may proceed with generating the certificate request.

Step 1: Generate CSR (Certificate Signing Request)

Generate your CSR as prescribed by your web server software. You will need the CSR when you go to the Thawte Website to request your certificate. It is recommended that you specify at least a 1024-bit key length when generating your CSR. Some browsers have begun issuing warning messages if the key length is less than 900 bits, and users may find these messages confusing or alarming.
