Unable to import .PFX in Project Options

Yeditha, | Last updated: Aug 13, 2020 04:54PM UTC

I have a client side certificate in ".cer" format it has no provate ekys. I wanted to use this certificate in burp tool for testing. I used the "Project Options > TLS > Client TLS Certificates " and then used the "Add" option to add the certificate. I read in your previous posts that burp support .p12 or .pfx file. I have converted .Cer I have to .pfx using below "openssl" commands: ---> openssl pkcs12 -export -in CerFileIn.cer -nokeys -out CerFileOut.pfx ---> openssl pkcs12 -export -in CerFileIn.cer -certfile CerFileIn.cer -out CerFileOut.pfx -nokeys I have tried importing .pfx generated using both commands, Burp fails with the following error "Failed to load Certificate : Unable to retrieve certificate " I run On : Burp Suite Professional v2020.7 [Debug ID: 9hbv6o87hnys6fszry4r:wcli] Please help me.

Burp supports a file in PKCS#12 format (.p12) or a hardware token or smart card in PKCS#11 format. Could you try using the file extension .p12 for your certificate?
