Subject Re: Java updates for Mac OS changes the password on jre_home/lib/security/cacerts

[Cross-posting to wss4j-dev and rampart-dev]


Thanks for sharing these findings. I encountered the same problem
while doing some tests with Rampart (WS-Security module for Axis2). I
am wondering why WSS4J actually accesses the cacerts file by
specifying a password (by default). Since the keystore contains only
public keys, it is perfectly possible to access it without specifying
a password (simply by passing null as second parameter to
KeyStore#load). One may argue that using a password to access a trust
store protects against tampering, but this is only true if a non
default secret password is used. Therefore I would expect WSS4J to
access cacerts without password unless one is explicitly specified
using the
property. Maybe somebody from the wss4j-dev list can shed some light
on this?
