Wikipedia defines Bitlocker as:
BitLocker Drive Encryption is a full disk encryption feature included with the Ultimate and Enterprise editions of Microsoft's Windows Vista and Windows 7 desktop operating systems, as well as the Windows Server 2008 and Windows Server 2008 R2 server platforms. It is designed to protect data by providing encryption for entire volumes.
I've heard that some maybe using Bitlocker for drive encryption in order to comply with FIPS 140-2.
The National Institute of Standards and Technology (NIST) issued the FIPS 140 Publication Series to coordinate the requirements and standards for cryptography modules that include both hardware and software components.
Does Bitlocker qualify as the cryptographic module defined in FIPS 140-2?
Are there any other pieces that are needed to fulfill the need for FIPS 140-2 security level 1 'cryptographic module' requirements?
