Function Documentation

int WFU_is_header_backup (  char *  volumePath  )  [static]

Determins whether the file referenced by volumePath is a header backup or an actual volume. Header backups are 2*HEADER_SIZE in length. If the file is 2*HEADER_SIZE in size, then it is assumed to be a backup. Parameters: volumePath  is the path to the file. Returns: 1 if the file is 2*HEADER_SIZE (assumed to be a header backup) 0 if the file is not 2*HEADER_SIZE

char* WFU_ReadHeader (  char *  volumePath, int  type, int  is_header_backup )  [static]

This function reads the salt from the header of the volume. Normal and hidden headers can be exained in a volume for or a header bakcup file. Parameters: volumePath  the path of the file. type  WFU_NORMAL or WFU_HIDDEN is_header_backup  0 indicates are regular file, 1 indicates a header backup file. Returns: The return value is a pointer to a static structure containing the salt.

BOOL WFU_Restore (  char *  username, char *  volumePath )  [static]

This function restores the CRYPTO_INFO data to a volume or a header bakcup file. Parameters: username  The username of the user performing the restore. This user must be authorized to perform restore actions. volumePath  the path of the file. Returns: true indicates success, false indicates failure.
