PMC Ciphers announce the release of version 6.1 of its BPP Disk Encryption software (For Windows XP, Windows 2000, and Windows 2003 Server). BPP Disk creates and manages encrypted virtual volumes on a computer's hard drive and/or other external storage devices. BPP Disk utilizes PMC's 512-bit Polymorphic Cipher to provide transparent on-the-fly encryption of data. This Polymorphic Encryption Technology first became available for public use in 1999 when it was released from its classified status by the German government.

Key features of BPP Disk include:

-Ultra-strong/ultra-fast 512 bit Polymorphic Encryption
-Transparent on-the-fly encryption of data
-Intuitive user interface
-Up to 2 Terabyte partition size
-Encryption of large NTFS partitions and creation of -encrypted file-hosted volumes
-Easy installation and deployment
-Encrypted volumes can be shared over corporate network
-Reliable continuous operation
-Support of external storage devices such as USB and -Firewire drives
-Maximum protection: Unprotected data never resides on an encrypted BPP Disk

To the operating system, encrypted BPP Disk volumes look exactly like the A: or C: drive. When a drive is unlocked, the user is able to access information from i-t just as if it was any other drive on the computer. O-nly the specific portion of a file that is in use is decrypted and passed "on the fly" to the operating system. Unprotected data never resides on an encrypted BPP Disk drive even when it is unlocked.
