[jira] Resolved: (JSPWIKI-20) Password hash should be salted

     [ https://issues.apache.org/jira/browse/JSPWIKI-20?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andrew Jaquith resolved JSPWIKI-20.
-----------------------------------

    Resolution: Fixed
      Assignee: Andrew Jaquith  (was: Janne Jalkanen)

Fixed in 2.7.0-svn-24. The change notes:

* Passwords are now salted and hashed per RFC 2307. Every password is salted with a 8-byte random salt.

* The sort-of-secret "share container user accounts with JDBCUserDatabase" option has been permanently removed, and will not be replaced. This was previously added to make it easier for users to add themselves to JDBC-based container realms. However, the switch to salted passwords precludes the continued use of this option. So it's gone and won't come back.

* Added a new class CryptoUtil that allows admins to generate SSHA password hashes (and verify an existing password given a supplied hash) at the command line. See the Javadoc for com.ecyrd.jspwiki.util.CryptoUtil for details.

> The password hash is calculated as a direct SHA1-digest of the password.  Unfortunately this means that it's vulnerable to brute-force attacks - there are many web sites which store SHA1 hashes of common passwords.  The key space in most languages is pretty small... So the password should really be properly salted with preferably a long, random string.
