Subject Re: How to change KeyStore type?
Date Mon, 21 Jan 2008 17:23:19 GMT
Providing a keystoreType attribute does not seem to be a big deal.  But, if
the Keystores portlet has to allow creating all types of keystores, it gets
really messy.  Here is one more observation.
    *IBMJDK does not allow storing an empty PKCS12 keystore to disk.*

This prevents creating an empty PKCS12 keystore and then adding which ever
keys and certificates the user wants to.

Here is the approach I want to take.
Step 1.  Provide a keystoreType attribute in FileKeystoreInstance.
Step 2.  Update KeyStores portlet to allow creation of all keystore types
that the JDK allows to store an empty keystore to disk.

Step 1 will allow the users to replace a keystore file of one type with that
of another type,  change the keystoreType in config.xml and get the server
Step 2 will allow users to manage all keystore types using Keystores portlet
and there is no hard-coding of any keystoreType except for geronimo-default
keystore which is JKS.

Now to some pitfalls.
1. If keystore type other than JKS is in use, the user may not be able to
switch JDK's for reasons like PKCS12 keystore created using IBMJDK are not
readble using SUNJDK.
2. Though IBMJDK does not allow creating an empty PKCS12 (and a few other
types) keystore as a starting point for managing a PKCS12 keystore, the
users can always add a PKCS12 keystore to var/security/keystores and the
gbean definition to config.xml.  This will make the keystore manageable
through KeyStores portlet as long as the keystore is not empty.

This will require a change in interface, etc.  I
doubt if we can consider this change for branches\2.0.
