Install CA in Burpsuite

Robert | Last updated: May 28, 2020 09:04AM UTC

Hi all, I am just getting started in Burpsuite and having trouble installing the CA. In the latest version of Burpsuite, the dialog asks to import the CA (which I have). But it ALSO is asking for the private key to import. When I downloaded the CA from Portswigger, I didn't see a private key. But I DID download the .pem file. I thought this might have been useful, but the dialog says it's not the correct format. "Failed to import certificate: Java.security.spe.InvalidKeySpecException:java.security.InvalidKeyException:invalid key format." Thanks for any help

Hi Robert, You install the Burp CA Certificate in your browser. Have you read the page below with instructions on how to do this for the browser that you are using? https://portswigger.net/support/installing-burp-suites-ca-certificate-in-your-browser

Hi Ben, Yes, I've installed in Mozilla, Firefox 76.0.1. What's weird is I had BurpSuite up and running for 30 mins, but then Firefox quit. Thanks,

Hi Robert, Just to confirm, it was working fine, Firefox quit and now it no longer works correctly?

Correct Ben. It was working fine for about 30 mins, then inexplicably stopped. I had to do my "real" job today. I'll troubleshoot tonight after din din. Thx,

Are you seeing some kind of error when you try and use it now? It might be useful to remove the certificate from Firefox completely and then go to Proxy -> Options and click the Regenerate CA certificate button. At this point you can go through the steps to import the certificate again in Firefox.
