Author: sdumitriu Date: 2007-04-23 22:23:53 +0200 (Mon, 23 Apr 2007) New Revision: 2957 Modified: xwiki/trunk/core/src/main/java/com/xpn/xwiki/objects/classes/ PasswordClass.java xwiki/trunk/core/src/main/java/com/xpn/xwiki/objects/meta/ PasswordMetaClass.java xwiki/trunk/core/src/main/java/com/xpn/xwiki/plugin/packaging/ Package.java xwiki/trunk/core/src/main/java/com/xpn/xwiki/user/impl/xwiki/ XWikiAuthServiceImpl.java Log: XWIKI-70: password can be searched XWIKI-580: Implement HASH password mechanism Added support for hashing passwords. There's some code related to encrypting passwords, but the actual encrypt/decrypt mechanism is not written yet.
