Functions

stretch	Stretch a password with a specified salt.
derive_user_key	Derive an AES key from a given user passphrase.
derive_recovery_key	Derive an AES key from a given recovery password.
check_recovery_password	Check if a given recovery password is valid.

dissect.fve.bde.keys.stretch(password: bytes, salt: bytes, rounds: int = 1048576) → bytes

Stretch a password with a specified salt.

Bitlocker uses this as the key derivation algorithm.

dissect.fve.bde.keys.derive_user_key(user_password: str) → bytes

Derive an AES key from a given user passphrase.

dissect.fve.bde.keys.derive_recovery_key(recovery_password: str) → bytes

Derive an AES key from a given recovery password.

dissect.fve.bde.keys.check_recovery_password(recovery_password: str) → bool

Check if a given recovery password is valid.
