Burp's CA certificate is expired

Darek | Last updated: May 31, 2023 01:15PM UTC

Hi, I'm able to reach out to http://burpsuite in Chrome. I downloaded CA Certificate -> cacert.der However, the file which I downloaded is the expired CA certificate which I'm not able to add to Keychain Access on MacOS. Certificate: Data: Version: 3 (0x2) Serial Number: 1393325211 (0x530c749b) Signature Algorithm: sha256WithRSAEncryption Issuer: C=PortSwigger, ST=PortSwigger, L=PortSwigger, O=PortSwigger, OU=PortSwigger CA, CN=PortSwigger CA Validity Not Before: Feb 25 10:46:51 2014 GMT Not After : May 5 09:46:51 2022 GMT Subject: C=PortSwigger, ST=PortSwigger, L=PortSwigger, O=PortSwigger, OU=PortSwigger CA, CN=PortSwigger CA Could you please guide me how to download the valid cert? Could it be related to the fact that I'm using Community Edition? Thanks

Hi Darek, Assuming you are running a later version of Burp, if you click the Settings button and navigate to the Tools -> Proxy -> Proxy listeners section and then click the 'Regenerate CA certificate' button this should create a new version of the Burp CA certificate for you. If you then obtain this new certificate via http://burpsuite, does this then work for you?
