[java] How can I use different certificates on specific connections?

If creating a SSLSocketFactory is not an option, just import the key into the JVM

  1. Retrieve the public key: $openssl s_client -connect dev-server:443, then create a file dev-server.pem that looks like

    -----BEGIN CERTIFICATE----- 
    lklkkkllklklklklllkllklkl
    lklkkkllklklklklllkllklkl
    lklkkkllklk....
    -----END CERTIFICATE-----
    
  2. Import the key: #keytool -import -alias dev-server -keystore $JAVA_HOME/jre/lib/security/cacerts -file dev-server.pem. Password: changeit

  3. Restart JVM
