}

An error decoding or unlocking a BitLocker (BDE) volume.

Variants

Io(Error)

An I/O error reading the underlying volume.

NotBitLocker

The volume header carries neither a BitLocker -FVE-FS- signature nor a BitLocker To Go MSWIN4.1 signature. The offending bytes at offset 3 are included so the caller can identify what was actually there.

Fields

signature: [u8; 8]

The 8 bytes found at offset 3 of the volume header.

NoValidMetadata

No FVE metadata block carried a valid -FVE-FS- block-header signature at any of the three candidate offsets read from the volume header.

Fields

offsets: [u64; 3]

The three candidate byte offsets tried.

UnsupportedEncryptionMethod

The volume’s encryption method is not one this build decrypts. The raw method value is included.

Fields

method: u16

The raw 16-bit encryption-method value from the metadata header.

NoPasswordProtector

The metadata carries no password-protected VMK (protection type 0x2000), so unlock_with_password cannot proceed. The protector types that were present are listed to guide the examiner toward the right unlock path.

Fields

found: Vec<u16>

The key-protection types that were present.

MissingKeyMaterial

The password-protected VMK is missing its stretch key or AES-CCM key entry, so the VMK cannot be derived. Names which part is absent.

Fields

what: &'static str

Which required sub-entry was absent (e.g. “stretch key”, “AES-CCM key”).

AuthenticationFailed

The AES-CCM authentication tag did not verify — for a password unlock this means the supplied password is wrong; for FVEK it means the VMK is wrong.

Fields

what: &'static str

Which key was being unwrapped (“volume master key” or “FVEK”).

MalformedKeyContainer

A decrypted key container was shorter than the fixed layout requires, or a key field ran past the end of the plaintext.

Fields

what: &'static str

Which container (“volume master key” or “FVEK”).

got: usize

Bytes actually present.

need: usize

Minimum bytes the layout requires.

Trait Implementations

impl Debug for BdeError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for BdeError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for BdeError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for BdeError

fn from(source: Error) -> Self

Converts to this type from the input type.
