blwipe is a tool that performs cryptographic erasure on BitLocker volumes. This allows you to "erase" BitLocker volumes very quickly by just overwriting areas where the key material are stored on the volume.
The tool is written in Go, so it should compile into a "static" binary and is easily cross-compilable.
You will need to install Go.
To download and compile blwipe, use
go get github.com/geekman/blwipe
blwipe executable should now be in your
Run blwipe on the BitLocker volume image to display details about the volume:
It should tell you the location of the metadata blocks.
If you want it to dump the parsed structures, pass
You can also use the entire device (e.g.
/dev/sda) or image file and specify
an offset to use, for example
-offset 0x10000 if the partition starts there.
The specified offset can be of other bases, as long as you specify the right
0 for octal,
0x for hex).
To actually wipe the volume, pass the
blwipe -wipe /dev/sda1
You will NOT receive any prompts or confirmation.
