Dislocker - FUSE driver to open BitLocker encrypted drive on macOS/Linux. Dislocker is a tool to decrypt/unlock BitLocker encrypted drive on macOS or Linux developed by Romain Coltel. 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 password for the decryption. Dislocker requires the PolarSSL library to work.
