DriveCrypt
Y a continuación algo de información sobre el mismo:
Cita: DriveCrypt Plus Pack provides true real-time "on the fly" 256-bit disk
encryption. Providing advanced FDE (Full disk encryption) as apposed
to VDE (Virtual disk encryption) or "container" encryption, DCPP is an
important evolutionary step in the field of transparent data
protection.
DCPP allows you to secure your disk(s) (including removable
media) with a powerful and proven encryption algorithm (AES-256) at
the sector level , ensuring that only authorized users may access it.
The encryption algorithm used by DCPP is a trusted, validated algorithm
chosen by the National Institute of Standards and Technology (NIST)
and slated to be the cryptographic standard for years to come. AES-256
is a FIPS-approved symmetric encryption algorithm that may be used by
U.S. Government organizations (and others) to protect sensitive
information.
DCPP is automatic and completely transparent to the user.
