GetKeyProtectorNumericalPassword method of the Win32_EncryptableVolume class
The GetKeyProtectorNumericalPassword method of the Win32_EncryptableVolume class retrieves the numerical password for a given key protector of the appropriate type.
The key protector identifier must refer to a key protector of type "Numerical Password".
uint32 GetKeyProtectorNumericalPassword( [in] string VolumeKeyProtectorID, [out] string NumericalPassword );
A unique string identifier used to manage an encrypted volume key protector.
A string that represents the password that can be used to unlock the corresponding volume.
The numerical password is 48 digits. These digits are divided into 8 groups of 6 digits, with the last digit in each group indicating a checksum value for the group. Assuming that a group of six digits is labeled as x1, x2, x3, x4, x5, and x6, the checksum x6 digit is calculated as –x1+x2–x3+x4–x5 mod 11.
The groups of digits are separated by a hyphen. Therefore, "xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx" is the format of the returned password.
This method returns one of the following codes or another error code if it fails.
||The method was successful.
||The volume is locked.
||The VolumeKeyProtectorID parameter does not refer to a key protector of the type "Numerical Password".
||BitLocker is not enabled on the volume. Add a key protector to enable BitLocker.
