Verizon Galaxy Nexus manual Work with CA certificates

Work with CA certificates

If a certificate authority (CA) certificate gets compromised, or for some other reason your organization doesn't want to trust it, you can disable or remove it. To do so, follow these steps:

1From a Home or All Apps screen, touch the Settings icon .

2Go to Personal > Security > Credential storage >Trusted credentials. The trusted credentials screen has two tabs:

System displays certificate authority (CA) certificates that are permanently installed in the ROM of your phone.

User displays any CA certificates that you have installed yourself, for example in the process of installing a client certificate.

3To examine the details of CA certificate, touch its name. A scrolling screen displays the details.

4To remove or disable a CA certificate, scroll down to the bottom of the details screen and touch either Disable for system certificates or Remove for user certificates.

When you disable a system CA certificate, the button at the bottom of its details screen changes to Enable, so you can enable the certificate again if necessary. When you remove a user-installed CA certificate, it is gone permanently and must be re-installed if you want it back.

5In the confirmation dialog that appears, click OK.
