Browsers to Begin Blocking Websites Using SHA-1 SSL Certificates (4349424)

Browsers to Begin Blocking Websites Using SHA-1 SSL Certificates

The major browser vendors have announced that they will soon start blocking access to websites that use SHA-1 SSL web server certificates.

Customers should ensure that a SHA-2 web server certificate is installed on their TPAM appliance(s) to ensure that access to the appliance is not impacted.

If a SHA-1 certificate is installed on the TPAM appliance(s), and the browsers have started enforcing the restriction, refer to documentation or FAQs for the browser to see if there is a way to override this check.  

If there is no way to override the check, then a prior version of the browser that does not enforce this requirement must be used to access the TPAM appliance(s).  

Note that neither of these methods are recommended.  Instead, a SHA-2 certificate should be imported into TPAM.
