Implementation Differences Between Windows VersionsMany of the differences between Windows Server 2003 and Windows 2000 were first implemented in Windows XP Professional, which added the following:Ability to work with offline filesAbility to back up keys directly from the command line and from the File Details property pageStronger encryption algorithmsMultiple user access to encrypted filesAbility to use WebDAV to store encrypted files on the server Also new but dependent on the implementation of Windows Server 2003 Certification Authority is the ability to centrally archive the user's private encryption key. This capability provides efficient recovery management, something that has been missing and is desperately needed. The new process, known as key archival, means that instead of recovering the file, the encryption key is recovered. Not only is this a sounder practice than relying on a file recovery agent, but also the key recovery agent, unlike the file recovery agent, does not automatically have the ability to read the file. The key recovery agent is able to retrieve the private key and return it instead of a decrypted file to the owner.Chapter 12.
