If you type a protection password (File menu, Save As command, Options dialog box), the FILEPASS record appears in the BIFF file. The wProtPass field contains the encrypted password. All records after FILEPASS are encrypted; you cannot read these encrypted records.
Note that this record specifies a file protection password, as opposed to the PASSWORD record (type 13h), which specifies a sheet-level or workbook-level protection password.
