I have a keystore object that I added a public key to, as follows:
storage.setKeyEntry("mypublickey" ,pubkey,"pubkeypassword".toCharArray(), null);
I then try to pull the public key back out with this line:
pubkey = (PublicKey)storage.getKey("mypublickey","pubkeypassword".toCharArray());
but the call throws an exception:
java.security.UnrecoverableKeyException: DER input, Integer tag error"
anyone know what causes this? i can get an enumeration of the aliases and list the key just fine, but cannot get it out of the keystore.
thanks,
jon

after searching the net for hours, it turns out the problem is how the KeyStore is initialized. the java tutorial on the sun site says that the default provider should be fine, but it's not.

hope that saves someone some agony.

GOD BLESS YOU JON!!!
I can pass one further tip on for using keystores...
Don't try and create one manually the first time. It don't work!
I got this from somewhere else on the web - here is my function for creating keystores - it basically invokes the keystore tool and then picks up the output.
You may have to edit it a little...
Again, hope it helps someone, like Jon helped me :-)
