dislocker is a tool to decrypt Microsoft’s BitLocker encrypted volumes from Linux or OSX. dislocker uses a fuse based mechanism to decrypt the volume and mount it so that the user can access (read or write) the files within the volume. Note that this is not a brute force mechanism or hack; the user still needs to provide a valid BEK file (startup key) or numerical key or FVEK (Full Volume Encryption Key) or recovery password or user password for the decryption.
I don't have any encrypted volumes to test this with; it was mentioned on the Debian forums, so I wanted to see if it could be backported. It could be useful for those that work in mixed OS environments. A how-to from 2014 is here.
