How can I use different certificates on specific connections?

Question

A module I\'m adding to our large Java application has to converse with another company\'s SSL-secured website. The problem is that the site uses a self-signed certificate.

Answer 1

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
