BestCrypt software opens a new class of Volume Encryption products. With the software users can encrypt old MS-DOS style disk partitions as well as modern volumes residing on a number of physical disk devices, for example Spanned, Striped, Mirrored or RAID-5 volumes. BestCrypt Volume Encryption can encrypt volumes where Windows boots from, as well as the volume where Windows stores its system files (including Registry, Page file and Hibernate file). Initial encryption is transparent both for running applications and for Windows system modules. BestCrypt Volume Encryption performs Computer Pre-Boot Authentication if system or boot volume/partition is encrypted.
