Certutil is a really useful tool for administering various parts of a Microsoft CA, but not all the switches are documented – they don’t even show up when you do a ‘certutil -v -?’ to show the full help.

So far, I have found the following verbs and options – the verbs have documentation if you specify them on the command line e.g. ‘certutil -setsmtpinfo -v -?’ I have only included the ‘hidden’ verbs and options below – you can find the standard options by checking the certutil help.

If you have any other verbs and options I’ve missed, please let me know in the comments and I’ll add them to this page. If you have any clever ways of using certutil, please let me know – I’m always looking for better ways of doing things!

Note: Microsoft may have hidden these options for a reason – use them with care, and at your own risk! Microsoft probably won’t provide support if you hit problems!
