How do I programmatically import a public key .cer file into a java keystore using JSSE?

Question

I want to take a public key .cer file generated from java keytool command like this:

"keytool -export -alias privatekey -file publickey.cer -keystore privateKeys.store"

and import it into a new, empty java keystore like this:

"keytool -import -alias publiccert -file publickey.cer -keystore publicCerts.store"

except I want to do the import programmatically, using JSSE.

Stack Overlords, work your magic! Thanks!

Answer 1

If you use jad to decompile the tools.jar that comes with Sun JDK, you will see exactly how it works.

Unzip the tools.jar in a folder and use the following command to decompile all classes inside that jar.

for i in $(find . -name "*.class" | perl -ple 's/\.class$//g'); do jad -p $i.class > $i.java; done

The keytool source can be seen in class sun.security.tools.KeyTool
