SSL certificates and gatling

Gatling (Open-Source)
1

Hi guys.
I have a private server which provides some api. Also I have a *.p12 certificate file for signing requests to private api. How can I prepare gatling to use this certificate for signing api requests?

Command for exporting p12 to jks: keytool -importkeystore -srckeystore path_to_cert_directory/certificate.p12 -destkeystore path_to_cert_directory/certificate.jks -srcstoretype pkcs12

P.S. I tried some cases of exporting p12 file to jks and gatling config but got nothing for all of they. First case gave me “Connection timed out” error. Second gave “No trusted certificate found” (see exception below)
P.S.S. gatling version is 1.5

Thanks in advance!

I can’t reply in length for now. Key tool can’t export the private keys. You probably have to set up the keystore to use your p12 file (PKCS12 type). Check out Oracle documentation.
