Does RMS use FIPS–certified encryption?
In RMS with Service Pack 1 and later, the lockboxes generated by the RMS client application use FIPS certified AES encryption when the client is installed on a computer running Windows XP or Windows Server 2003. However, if the RMS client is installed on computers running Windows 2000, a FIPS-certified AES library is not installed, so those lockboxes are not FIPS-compliant.
