IsNumericalPasswordValid method of the Win32_EncryptableVolume class

The IsNumericalPasswordValid method of the Win32_EncryptableVolume class indicates whether the numerical password meets the special format requirements for this authentication value.

Syntax


uint32 IsNumericalPasswordValid(
  [in]   string NumericalPassword,
  [out]  boolean IsNumericalPasswordValid
);

Parameters

NumericalPassword [in]

Type: string

A string that specifies the numerical password.

The numerical password must contain 48 digits. These digits can be divided into 8 groups of 6 digits, with the last digit in each group indicating a checksum value for the group. Each group of 6 digits must be divisible by 11 and must be less than 720896. Assuming 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 can optionally be separated by a space or hyphen. Therefore, "xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx" or "xxxxxx xxxxxx xxxxxx xxxxxx xxxxxx xxxxxx xxxxxx xxxxxx" may also contain valid numerical passwords.

IsNumericalPasswordValid [out]

Type: boolean

A Boolean value that is true if the numerical password meets the special format requirements for this authentication value, otherwise the value is false.

Return value

Type: uint32

This method returns one of the following codes or another error code if it fails.

Return code/valueDescription
S_OK
0 (0x0)

The method was successful.
