1427 reghack - windows 3.11 registry data format demo program.
1428
1429 The reg.dat file has 3 parts, a header, a table of 8-byte entries that is
1430 a combined hash table and tree description, and finally a text table.
1431
1432 The header is obvious from the struct header. The taboff1 and taboff2
1433 fields are always 0x20, and their usage is unknown.
1434
1435 The 8-byte entry table has various entry types.
1436
1437 tabent[0] is a root index. The second word has the index of the root of
1438 the directory.
1439 tabent[1..hashsize] is a hash table. The first word in the hash entry is
1440 the index of the key/value that has that hash. Data with the same
1441 hash value are on a circular list. The other three words in the
1442 hash entry are always zero.
1443 tabent[hashsize..tabcnt] is the tree structure. There are two kinds of
1444 entry: dirent and keyent/valent. They are identified by context.
1445 tabent[freeidx] is the first free entry. The first word in a free entry
1446 is the index of the next free entry. The last has 0 as a link.
1447 The other three words in the free list are probably irrelevant.
1448
1449 Entries in text table are preceeded by a word at offset-2. This word
1450 has the value (2*index)+1, where index is the referring keyent/valent
1451 entry in the table. I have no suggestion for the 2* and the +1.
1452 Following the word, there are N bytes of data, as per the keyent/valent
1453 entry length. The offset of the keyent/valent entry is from the start
1454 of the text table to the first data byte.
1455
1456 This information is not available from Microsoft. The data format is
1457 deduced from the reg.dat file by me. Mistakes may
1458 have been made. I claim no rights and give no guarantees for this program.
