如何从系统中删除证书颁发机构的证书？

该ca-certificates软件包刚刚更新，它对我的​​Xubuntu 13.10系统造成了以下更改：

Running hooks in /etc/ca-certificates/update.d....
Adding debian:CA_Disig_Root_R1.pem
Adding debian:CA_Disig_Root_R2.pem
Adding debian:China_Internet_Network_Information_Center_EV_Certificates_Root.pem
Adding debian:D-TRUST_Root_Class_3_CA_2_2009.pem
Adding debian:D-TRUST_Root_Class_3_CA_2_EV_2009.pem
Adding debian:PSCProcert.pem
Adding debian:StartCom_Certification_Authority_2.pem
Adding debian:Swisscom_Root_CA_2.pem
Adding debian:Swisscom_Root_EV_CA_2.pem
Adding debian:TURKTRUST_Certificate_Services_Provider_Root_2007.pem
Adding debian:Verisign_Class_3_Public_Primary_Certification_Authority_2.pem
Removing debian:cacert.org_class3.pem
Removing debian:cacert.org_root.pem
Removing debian:Equifax_Secure_eBusiness_CA_2.pem
Removing debian:TC_TrustCenter_Universal_CA_III.pem

我已经决定我不信任其中一些CA，并且希望删除其证书。我怎么做？

跑

sudo dpkg-reconfigure ca-certificates

那应该给您一个列表，您可以在其中取消选择CA。

CA列表存储在文件中/etc/ca-certificates.conf。如果您手动编辑此文件，则需要运行

sudo update-ca-certificates

更新实际的证书/etc/ssl/certs/（如果使用dpkg-reconfigure，则自动完成）。

请参阅/usr/share/doc/ca-certificates/README.Debian以获取更多信息。
