VeriSign Code Signing CRL Procedure

Version 1.2
Date: 4/19/2004

Background
When a customer or VeriSign revokes a Code Signing certificate for reasons defined in section 1.a below, the certificate is published on a publicly accessible Certificate Revocation List (CRL).

VeriSign's Certificate Practices Statement allows VeriSign to remove an expired Code Signing Certificate from a CRL after it has expired.

As of 2/1/2004, VeriSign has implemented specific procedures to be followed before a Code Signing Certificate can be removed from a CRL in accordance with the CPS.


CRL and Revocation Procedure

1. Revocation for a Security Reason:
a. VeriSign will never remove a certificate from a CRL if VeriSign has reason to believe that it was revoked for (i) reasons of a private key compromise or (ii) because the Certificate was issued in a manner not materially in accordance with the procedures required by the VeriSign CPS (a "security reason"). Examples of revocation reasons that VeriSign does not believe constitute security reasons include "Lost or forgotten password" and "Replacement".
b. Commencing on 2/11/04, only Code Signing certificates that are revoked for a Security Reason will be published to a CRL. VeriSign has adopted this policy to ensure that only certificates revoked for security reasons (as opposed to standard certificate lifecycle reasons) are included in the CRL.
2. Revocation for a Non-Security Reason:
a. If VeriSign has a clear and unambiguous revocation reason on file, revoked certificates will be removed from the CRL after they have expired unless VeriSign has reason to believe that they were revoked for a Security Reason. Examples of revocation reasons that VeriSign does not believe constitute security reasons include "Lost or forgotten password" and "Replacement".
b. If VeriSign does not have a clear and unambiguous revocation reason on file, a revoked certificate may be removed from the CRL ONLY after (i) the certificate has been revoked for more than 2 years and (ii) the notification procedures in 2(c) are followed.
c. As an added precaution, prior to removing any revoked certificate from the CRL:
  i. VeriSign will notify in advance the Technical Contacts listed in the revoked certificate request of this CRL procedure and the pending removal of revoked certificate from the CRL.
  ii. If the Technical Contact objects to the pending removal of revoked certificate from the CRL, the revoked certificate will not be removed from the CRL.
