r9628: rewrite profiles tool to use the regfio code.
Still have one bug to track down in it though.... (This used to be commit e69df2d2051d0e7e12b6a11f9c77490f619ba792)

-/*************************************************************************
-
- A utility to report and change SIDs in registry files
-
- Many of the ideas in here come from other people and software.
- I first looked in Wine in misc/registry.c and was also influenced by
- http://www.wednesday.demon.co.uk/dosreg.html
-
- Which seems to contain comments from someone else. I reproduce them here
- incase the site above disappears. It actually comes from
- http://home.eunet.no/~pnordahl/ntpasswd/WinReg.txt.
-
-The windows NT registry has 2 different blocks, where one can occure many
-times...
-
-the "regf"-Block
-================
-
-"regf" is obviously the abbreviation for "Registry file". "regf" is the
-signature of the header-block which is always 4kb in size, although only
-the first 64 bytes seem to be used and a checksum is calculated over
-the first 0x200 bytes only!
-
-Offset Size Contents
-0x00000000 D-Word ID: ASCII-"regf" = 0x66676572
-0x00000004 D-Word ???? //see struct REGF
-0x00000008 D-Word ???? Always the same value as at 0x00000004
-0x0000000C Q-Word last modify date in WinNT date-format
-0x00000014 D-Word 1
-0x00000018 D-Word 3
-0x0000001C D-Word 0
-0x00000020 D-Word 1
-0x00000024 D-Word Offset of 1st key record
-0x00000028 D-Word Size of the data-blocks (Filesize-4kb)
-0x0000002C D-Word 1
-0x000001FC D-Word Sum of all D-Words from 0x00000000 to
-0x000001FB //XOR of all words. Nigel
-
-I have analyzed more registry files (from multiple machines running
-NT 4.0 german version) and could not find an explanation for the values
-marked with ???? the rest of the first 4kb page is not important...
-
-the "hbin"-Block
-================
-I don't know what "hbin" stands for, but this block is always a multiple
-of 4kb in size.
-
-Inside these hbin-blocks the different records are placed. The memory-
-management looks like a C-compiler heap management to me...
-
-hbin-Header
-===========
-Offset Size Contents
-0x0000 D-Word ID: ASCII-"hbin" = 0x6E696268
-0x0004 D-Word Offset from the 1st hbin-Block
-0x0008 D-Word Offset to the next hbin-Block
-0x001C D-Word Block-size
-
-The values in 0x0008 and 0x001C should be the same, so I don't know
-if they are correct or swapped...
-
-From offset 0x0020 inside a hbin-block data is stored with the following
-format:
-
-Offset Size Contents
-0x0000 D-Word Data-block size //this size must be a
-multiple of 8. Nigel
-0x0004 ???? Data
-
-If the size field is negative (bit 31 set), the corresponding block
-is free and has a size of -blocksize!
-
-The data is stored as one record per block. Block size is a multiple
-of 4 and the last block reaches the next hbin-block, leaving no room.
-
-Records in the hbin-blocks
-==========================
-
-nk-Record
-
- The nk-record can be treated as a kombination of tree-record and
- key-record of the win 95 registry.
-
-lf-Record
-
- The lf-record is the counterpart to the RGKN-record (the
- hash-function)
-
-vk-Record
-
- The vk-record consists information to a single value.
-
-sk-Record
-
- sk (? Security Key ?) is the ACL of the registry.
-
-Value-Lists
-
- The value-lists contain information about which values are inside a
- sub-key and don't have a header.
-
-Datas
-
- The datas of the registry are (like the value-list) stored without a
- header.
-
-All offset-values are relative to the first hbin-block and point to the
-block-size field of the record-entry. to get the file offset, you have to add
-the header size (4kb) and the size field (4 bytes)...
-
-the nk-Record
-=============
-Offset Size Contents
-0x0000 Word ID: ASCII-"nk" = 0x6B6E
-0x0002 Word for the root-key: 0x2C, otherwise 0x20 //key symbolic links 0x10. Nigel
-0x0004 Q-Word write-date/time in windows nt notation
-0x0010 D-Word Offset of Owner/Parent key
-0x0014 D-Word number of sub-Keys
-0x001C D-Word Offset of the sub-key lf-Records
-0x0024 D-Word number of values
-0x0028 D-Word Offset of the Value-List
-0x002C D-Word Offset of the sk-Record
-
-0x0030 D-Word Offset of the Class-Name //see NK structure for the use of these fields. Nigel
-0x0044 D-Word Unused (data-trash) //some kind of run time index. Does not appear to be important. Nigel
-0x0048 Word name-length
-0x004A Word class-name length
-0x004C ???? key-name
-
-the Value-List
-==============
-Offset Size Contents
-0x0000 D-Word Offset 1st Value
-0x0004 D-Word Offset 2nd Value
-0x???? D-Word Offset nth Value
-
-To determine the number of values, you have to look at the owner-nk-record!
-
-Der vk-Record
-=============
-Offset Size Contents
-0x0000 Word ID: ASCII-"vk" = 0x6B76
-0x0002 Word name length
-0x0004 D-Word length of the data //if top bit is set when offset contains data. Nigel
-0x0008 D-Word Offset of Data
-0x000C D-Word Type of value
-0x0010 Word Flag
-0x0012 Word Unused (data-trash)
-0x0014 ???? Name
-
-If bit 0 of the flag-word is set, a name is present, otherwise the value has no name (=default)
-
-If the data-size is lower 5, the data-offset value is used to store the data itself!
-
-The data-types
-==============
-Wert Beteutung
-0x0001 RegSZ: character string (in UNICODE!)
-0x0002 ExpandSZ: string with "%var%" expanding (UNICODE!)
-0x0003 RegBin: raw-binary value
-0x0004 RegDWord: Dword
-0x0007 RegMultiSZ: multiple strings, separated with 0
- (UNICODE!)
-
-The "lf"-record
-===============
-Offset Size Contents
-0x0000 Word ID: ASCII-"lf" = 0x666C
-0x0002 Word number of keys
-0x0004 ???? Hash-Records
-
-Hash-Record
-===========
-Offset Size Contents
-0x0000 D-Word Offset of corresponding "nk"-Record
-0x0004 D-Word ASCII: the first 4 characters of the key-name, padded with 0's. Case sensitiv!
-
-Keep in mind, that the value at 0x0004 is used for checking the data-consistency! If you change the
-key-name you have to change the hash-value too!
-
-//These hashrecords must be sorted low to high within the lf record. Nigel.
-
-The "sk"-block
-==============
-(due to the complexity of the SAM-info, not clear jet)
-
-Offset Size Contents
-0x0000 Word ID: ASCII-"sk" = 0x6B73
-0x0002 Word Unused
-0x0004 D-Word Offset of previous "sk"-Record
-0x0008 D-Word Offset of next "sk"-Record
-0x000C D-Word usage-counter
-0x0010 D-Word Size of "sk"-record in bytes
-???? //standard self
-relative security desciptor. Nigel
-???? ???? Security and auditing settings...
-????
-
-The usage counter counts the number of references to this
-"sk"-record. You can use one "sk"-record for the entire registry!
-
-Windows nt date/time format
-===========================
-The time-format is a 64-bit integer which is incremented every
-0,0000001 seconds by 1 (I don't know how accurate it realy is!)
-It starts with 0 at the 1st of january 1601 0:00! All values are
-stored in GMT time! The time-zone is important to get the real
-time!
-
-Common values for win95 and win-nt
-==================================
-Offset values marking an "end of list", are either 0 or -1 (0xFFFFFFFF).
-If a value has no name (length=0, flag(bit 0)=0), it is treated as the
-"Default" entry...
-If a value has no data (length=0), it is displayed as empty.
-
-simplyfied win-3.?? registry:
-=============================
-
-+-----------+
-| next rec. |---+ +----->+------------+
-| first sub | | | | Usage cnt. |
-| name | | +-->+------------+ | | length |
-| value | | | | next rec. | | | text |------->+-------+
-+-----------+ | | | name rec. |--+ +------------+ | xxxxx |
- +------------+ | | value rec. |-------->+------------+ +-------+
- v | +------------+ | Usage cnt. |
-+-----------+ | | length |
-| next rec. | | | text |------->+-------+
-| first sub |------+ +------------+ | xxxxx |
-| name | +-------+
-| value |
-+-----------+
-
-Greatly simplyfied structure of the nt-registry:
-================================================
-
-+---------------------------------------------------------------+
-| |
-v |
-+---------+ +---------->+-----------+ +----->+---------+ |
-| "nk" | | | lf-rec. | | | nk-rec. | |
-| ID | | | # of keys | | | parent |---+
-| Date | | | 1st key |--+ | .... |
-| parent | | +-----------+ +---------+
-| suk-keys|-----+
-| values |--------------------->+----------+
-| SK-rec. |---------------+ | 1. value |--> +----------+
-| class |--+ | +----------+ | vk-rec. |
-+---------+ | | | .... |
- v | | data |--> +-------+
- +------------+ | +----------+ | xxxxx |
- | Class name | | +-------+
- +------------+ |
- v
- +---------+ +---------+
- +----->| next sk |--->| Next sk |--+
- | +---| prev sk |<---| prev sk | |
- | | | .... | | ... | |
- | | +---------+ +---------+ |
- | | ^ | |
- | +----------+ |
- +-------------------------------+
-
----------------------------------------------------------------------------
-
-Hope this helps.... (Although it was "fun" for me to uncover this things,
- it took me several sleepless nights ;)
