DriveCrypt Plus Pack - Version 3.9 DriveCrypt Plus Pack (DCPP) is a Full disk encryption software package which encrypts the operating system, and allows pre-boot authentication. The user can enter a password on computer start up, before the operating system boots up. DCPP is the only software on the market abel to hide the entire operating system inside another operating system. This is especially usefull if you are forced to reveal the password to an attacker. In this case he will only see prelared data. DCPP is the fastest and most feature-rich real-time encryption system available, Special care has been taken to render all cryptographic parts as invisible & transparent as possible. DriveCrypt Plus Pack provides true real-time "on the fly" 256-bit disk encryption. Providing advanced FDE (Full disk encryption) as opposed to VDE (Virtual disk encryption) or "container" encryption. 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. Not only does this decrease user involvement and training requirements, but also it creates the foundation for enforceable security. The careful integration of boot protection and automatic encryption provides a high degree of security with minimal impact on users. Boot protection prevents subversion of the operating system (via floppy boot-up, for example) or the introduction of rogue programs while sector by sector encryption makes it impossible to copy individual files for brute force attacks.
