Import a client TLS certificate

Umang | Last updated: Apr 07, 2020 06:59PM UTC

Hello, I have a client side certificate in ".pem" format. I wanted to use this certificate in burp tool for some testing. I used the "User Options > TLS > Client TLS Certificates " and then used the "Add" option to add the certificate. If I upload the certificate in ".pem" mode itself , it fails with the following error "Failed to load Certificate : toDerInputStream rejects tag type 115 " If I convert the ".pem" file to ".der" format using the "OpenSSL" tool, the upload of the certificate to Burp tool again fails with the error >>openssl x509 -outform DER -in <pem_certificate> -out <der_certificate> "Failed to load certificate : DER input , Integer tag error " How can I fix this?
