Function Documentation

uint8_t hk_getentry ( TSK_HDB_INFO hdb_info,
char *  hash,
OFF_T  offset,
TSK_HDB_FLAG_ENUM  flags,
TSK_HDB_LOOKUP_FN  action,
void *  cb_ptr 
)

Find the corresponding name at the given offset.

The offset was likely determined from the index. The entries in the DB following the one specified are also processed if they have the same hash value and their name is different. The callback is called for each entry.

Parameters:
hdb_info Data base to get data from.
hash MD5 hash value that was searched for
offset Byte offset where hash value should be located in db_file
flags 
action Callback used for each entry found in lookup
cb_ptr Pointer to data passed to callback
Returns:
1 on error and 0 on success

uint8_t hk_makeindex ( TSK_HDB_INFO hdb_info,
TSK_TCHAR *  dbtype 
)

Process the database to create a sorted index of it.

Consecutive entries with the same hash value are not added to the index, but will be found during lookup.

Parameters:
hdb_info Hash database to make index of
dbtype Text of type of database (should always be TSK_HDB_DBTYPE_HK_STR)
Returns:
1 on error and 0 on success.

uint8_t hk_test ( FILE *  hFile  ) 

Test the file to see if it is a hashkeeper database.

Parameters:
hFile File handle to hash database
Returns:
1 if hk and 0 if not
