Export certificates from java?

Question

We had some https certificates installed under java 5 keystore. I am looking forward to migrate my old ssl certificate from java 5 trustore to java 6 trustore or is it a good option to replace java 6 kdystore file wuth java 5 keystore file(though i wont prefer this)?

Answer 1

You can use:

• keytool -list to find the alias of the certificate you want to migrate,
• keytool -export -alias ... to export it into a file,
• keytool -import ... to import it into the new trust store. (The default password is changeit, except on some versions of OSX where it's changeme).
