%description
Dislocker has been designed to read BitLocker encrypted partitions ("drives")
under a Linux system. The driver used to only read volumes encrypted under a
Microsoft Windows 7 system - but is now Microsoft Windows Vista and 8 capable
and has the write functionality.

The file name where the BitLocker encrypted partition will be decrypted needs
to be given. This may take a long time, depending on the size of the encrypted
partition. But afterward, once the partition is decrypted, the access to the
NTFS partition will be faster than with FUSE. Another thing to think about is
the size of the disk (same size as the volume that is tried to be decrypted).
Nevertheless, once the partition is decrypted, the file can be mounted as any
NTFS partition and won't have any link to the original BitLocker partition.

%description -n fuse-dislocker
Dislocker has been designed to read BitLocker encrypted partitions ("drives")
under a Linux system. The driver used to only read volumes encrypted under a
Microsoft Windows 7 system - but is now Microsoft Windows Vista and 8 capable
and has the write functionality.

A mount point needs to be given to dislocker-fuse. Once keys are decrypted, a
file named 'dislocker-file' appears into this provided mount point. This file
is a virtual NTFS partition, it can be mounted as any NTFS partition and then
reading from it or writing to it is possible.
