Import client certificate from PKCS12 containing more than one cert
I work with a lot of p12 files that contain an encryption cert and a signing cert for the same user DN, often with the encryption cert first in the p12 file. I have inadvertently wasted more time than I want to admit banging my head against my keyboard that a p12 which works fine in Firefox is completely broken in Burp Pro. (eventually finding the problem, usually after setting up Wireshark, then I use openssl to break the p12 into smaller pieces).
So, feature request:
When importing a pkcs12 file that contains multiple certificates, the Burp Pro UI should allow me to select which one to use.
Thanks for letting us know about this. This has been requested before, and I agree, when there’s multiple, providing a list so the user can choose would be a good solution.
This is on the development plan, although realistically it’s likely to be some time until we get to it.
