Using a single certificate based on aliases from Java Key Store

Question

I have a keystore which has multiple keys and certificates added to it I want to used a certificate based on the aliases from the key store and use it for SSL I tried to set the following System properties but nothing helped

System.setProperty("javax.net.ssl.keyAlias", "abcd");
System.setProperty("javax.net.ssl.keyStoreAlias", "abcd");

It always uses the first certificate from the keystore instead of matching the key aliases

Answer 1

If you look at the Customization section of the JSSE Reference Guide (or the entire guide), there's no javax.net.ssl.keyAlias or javax.net.ssl.keyStoreAlias property.

It's up to the application to have a way to select which certificate it wants, using its alias name, but it has to load it explicitly itself. Some frameworks use their own properties or configuration options.
