|    The encryption/decryption parts of this source code (as opposed to the | ||||

|    (Prior to January 2000, re-export from the US was a violation of US law.) | ||||

| 
 | ||||
|   Polynomials over GF(2) are represented in binary, one bit per coefficient, | ||||
|   with the lowest powers in the most significant bit.  Then adding polynomials | ||||
|   is just exclusive-or, and multiplying a polynomial by x is a right shift by | ||||
|   one.  If we call the above polynomial p, and represent a byte as the | ||||
|   polynomial q, also with the lowest power in the most significant bit (so the | ||||
|   byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p, | ||||
|   where a mod b means the remainder after dividing a by b. | ||||
| 
 | ||||
|   This calculation is done using the shift-register method of multiplying and | ||||
|   taking the remainder.  The register is initialized to zero, and for each | ||||
|   incoming bit, x^32 is added mod p to the register if the bit is a one (where | ||||
|   x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by | ||||
|   x (which is shifting right by one and adding x^32 mod p if the bit shifted | ||||
|   out is a one).  We start with the highest power (least significant bit) of | ||||
|   q and repeat for all eight bits of q. | ||||
| 
 | ||||
|   The table is simply the CRC of all possible eight bit values.  This is all | ||||
|   the information needed to generate CRC's on data a byte at a time for all | ||||
|   combinations of CRC register values and incoming bytes. | ||||

|   Generate tables for a byte-wise 32-bit CRC calculation on the polynomial: | ||||
|   x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1. | ||||
| 
 | ||||
|   Polynomials over GF(2) are represented in binary, one bit per coefficient, | ||||
|   with the lowest powers in the most significant bit.  Then adding polynomials | ||||
|   is just exclusive-or, and multiplying a polynomial by x is a right shift by | ||||
|   one.  If we call the above polynomial p, and represent a byte as the | ||||
|   polynomial q, also with the lowest power in the most significant bit (so the | ||||
|   byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p, | ||||
|   where a mod b means the remainder after dividing a by b. | ||||
| 
 | ||||
|   This calculation is done using the shift-register method of multiplying and | ||||
|   taking the remainder.  The register is initialized to zero, and for each | ||||
|   incoming bit, x^32 is added mod p to the register if the bit is a one (where | ||||
|   x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by | ||||
|   x (which is shifting right by one and adding x^32 mod p if the bit shifted | ||||
|   out is a one).  We start with the highest power (least significant bit) of | ||||
|   q and repeat for all eight bits of q. | ||||
| 
 | ||||
|   The first table is simply the CRC of all possible eight bit values.  This is | ||||
|   all the information needed to generate CRCs on data a byte at a time for all | ||||
|   combinations of CRC register values and incoming bytes.  The remaining tables | ||||
|   allow for word-at-a-time CRC calculation for both big-endian and little- | ||||
|   endian machines, where a word is four bytes. | ||||

|    Decode literal, length, and distance codes and write out the resulting | ||||
|    literal and match bytes until either not enough input or output is | ||||
|    available, an end-of-block is encountered, or a data error is encountered. | ||||
|    When large enough input and output buffers are supplied to inflate(), for | ||||
|    example, a 16K input buffer and a 64K output buffer, more than 95% of the | ||||
|    inflate execution time is spent in this routine. | ||||
| 
 | ||||
|    Entry assumptions: | ||||
| 
 | ||||
|         state->mode == LEN | ||||
|         strm->avail_in >= 6 | ||||
|         strm->avail_out >= 258 | ||||
|         start >= strm->avail_out | ||||
|         state->bits < 8 | ||||
| 
 | ||||
|    On return, state->mode is one of: | ||||
| 
 | ||||
|         LEN -- ran out of enough output space or enough available input | ||||
|         TYPE -- reached end of block code, inflate() to interpret next block | ||||
|         BAD -- error in block data | ||||
| 
 | ||||
|    Notes: | ||||
| 
 | ||||
|     - The maximum input bits used by a length/distance pair is 15 bits for the | ||||
|       length code, 5 bits for the length extra, 15 bits for the distance code, | ||||
|       and 13 bits for the distance extra.  This totals 48 bits, or six bytes. | ||||
|       Therefore if strm->avail_in >= 6, then there is enough input to avoid | ||||
|       checking for available input while decoding. | ||||
| 
 | ||||
|     - The maximum bytes that a single length/distance pair can output is 258 | ||||
|       bytes, which is the maximum length that can be coded.  inflate_fast() | ||||
|       requires strm->avail_out >= 258 for each loop to avoid checking for | ||||

 | ||||
|    Huffman code decoding is performed using a multi-level table lookup. | ||||
|    The fastest way to decode is to simply build a lookup table whose | ||||
|    size is determined by the longest code.  However, the time it takes | ||||
|    to build this table can also be a factor if the data being decoded | ||||
|    is not very long.  The most common codes are necessarily the | ||||
|    shortest codes, so those codes dominate the decoding time, and hence | ||||
|    the speed.  The idea is you can have a shorter table that decodes the | ||||
|    shorter, more probable codes, and then point to subsidiary tables for | ||||
|    the longer codes.  The time it costs to decode the longer codes is | ||||
|    then traded against the time it takes to make longer tables. | ||||
| 
 | ||||
|    This results of this trade are in the variables lbits and dbits | ||||
|    below.  lbits is the number of bits the first level table for literal/ | ||||
|    length codes can decode in one step, and dbits is the same thing for | ||||
|    the distance codes.  Subsequent tables are also less than or equal to | ||||
|    those sizes.  These values may be adjusted either when all of the | ||||
|    codes are shorter than that, in which case the longest code length in | ||||
|    bits is used, or when the shortest code is *longer* than the requested | ||||
|    table size, in which case the length of the shortest code in bits is | ||||
|    used. | ||||
| 
 | ||||
|    There are two different values for the two tables, since they code a | ||||
|    different number of possibilities each.  The literal/length table | ||||
|    codes 286 possible values, or in a flat code, a little over eight | ||||
|    bits.  The distance table codes 30 possible values, or a little less | ||||
|    than five bits, flat.  The optimum values for speed end up being | ||||
|    about one bit more than those, so lbits is 8+1 and dbits is 5+1. | ||||
|    The optimum values may differ though from machine to machine, and | ||||
|    possibly even between compilers.  Your mileage may vary. | ||||

|        Process a set of code lengths to create a canonical Huffman code.  The | ||||
|        code lengths are lens[0..codes-1].  Each length corresponds to the | ||||
|        symbols 0..codes-1.  The Huffman code is generated by first sorting the | ||||
|        symbols by length from short to long, and retaining the symbol order | ||||
|        for codes with equal lengths.  Then the code starts with all zero bits | ||||
|        for the first code of the shortest length, and the codes are integer | ||||
|        increments for the same length, and zeros are appended as the length | ||||
|        increases.  For the deflate format, these bits are stored backwards | ||||
|        from their more natural integer increment ordering, and so when the | ||||
|        decoding tables are built in the large loop below, the integer codes | ||||
|        are incremented backwards. | ||||
| 
 | ||||
|        This routine assumes, but does not check, that all of the entries in | ||||
|        lens[] are in the range 0..MAXBITS.  The caller must assure this. | ||||
|        1..MAXBITS is interpreted as that code length.  zero means that that | ||||
|        symbol does not occur in this code. | ||||
| 
 | ||||
|        The codes are sorted by computing a count of codes for each length, | ||||
|        creating from that a table of starting indices for each length in the | ||||
|        sorted table, and then entering the symbols in order in the sorted | ||||
|        table.  The sorted table is work[], with that space being provided by | ||||
|        the caller. | ||||
| 
 | ||||
|        The length counts are used for other purposes as well, i.e. finding | ||||
|        the minimum and maximum length codes, determining if there are any | ||||
|        codes at all, checking for a valid set of lengths, and looking ahead | ||||
|        at length counts to determine sub-table sizes when building the | ||||

|        Create and fill in decoding tables.  In this loop, the table being | ||||
|        filled is at next and has curr index bits.  The code being used is huff | ||||
|        with length len.  That code is converted to an index by dropping drop | ||||
|        bits off of the bottom.  For codes where len is less than drop + curr, | ||||
|        those top drop + curr - len bits are incremented through all values to | ||||
|        fill the table with replicated entries. | ||||
| 
 | ||||
|        root is the number of index bits for the root table.  When len exceeds | ||||
|        root, sub-tables are created pointed to by the root entry with an index | ||||
|        of the low root bits of huff.  This is saved in low to check for when a | ||||
|        new sub-table should be started.  drop is zero when the root table is | ||||
|        being filled, and drop is root when sub-tables are being filled. | ||||
| 
 | ||||
|        When a new sub-table is needed, it is necessary to look ahead in the | ||||
|        code lengths to determine what size sub-table is needed.  The length | ||||
|        counts are used for this, and so count[] is decremented as codes are | ||||
|        entered in the tables. | ||||
| 
 | ||||
|        used keeps track of how many table entries have been allocated from the | ||||
|        provided *table space.  It is checked when a LENS table is being made | ||||
|        against the space in *table, ENOUGH, minus the maximum space needed by | ||||
|        the worst case distance code, MAXD.  This should never happen, but the | ||||
|        sufficiency of ENOUGH has not been proven exhaustively, hence the check. | ||||
|        This assumes that when type == LENS, bits == 9. | ||||

 | ||||
|        sym increments through all symbols, and the loop terminates when | ||||
|        all codes of length max, i.e. all codes, have been processed.  This | ||||

|      Decompresses the source buffer into the destination buffer.  sourceLen is | ||||
|    the byte length of the source buffer. Upon entry, destLen is the total | ||||
|    size of the destination buffer, which must be large enough to hold the | ||||
|    entire uncompressed data. (The size of the uncompressed data must have | ||||
|    been saved previously by the compressor and transmitted to the decompressor | ||||
|    by some mechanism outside the scope of this compression library.) | ||||
|    Upon exit, destLen is the actual size of the compressed buffer. | ||||
|      This function can be used to decompress a whole file at once if the | ||||
|    input file is mmap'ed. | ||||

| ZLIB DATA COMPRESSION LIBRARY | ||||
| 
 | ||||
| zlib 1.2.1 is a general purpose data compression library.  All the code is | ||||
| thread safe.  The data format used by the zlib library is described by RFCs | ||||
| (Request for Comments) 1950 to 1952 in the files | ||||
| http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format) | ||||
| and rfc1952.txt (gzip format). These documents are also available in other | ||||
| formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html | ||||
| 
 | ||||
| All functions of the compression library are documented in the file zlib.h | ||||
| (volunteer to write man pages welcome, contact zlib@gzip.org). A usage example | ||||
| of the library is given in the file example.c which also tests that the library | ||||
| is working correctly. Another example is given in the file minigzip.c. The | ||||
| compression library itself is composed of all source files except example.c and | ||||
| minigzip.c. | ||||
| 
 | ||||
| To compile all files and run the test program, follow the instructions given at | ||||
| the top of Makefile. In short "make test; make install" should work for most | ||||
| machines. For Unix: "./configure; make test; make install" For MSDOS, use one | ||||
| of the special makefiles such as Makefile.msc. For VMS, use Make_vms.com or | ||||
| descrip.mms. | ||||
| 
 | ||||
| Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant | ||||
| <info@winimage.com> for the Windows DLL version. The zlib home page is | ||||
| http://www.zlib.org or http://www.gzip.org/zlib/ Before reporting a problem, | ||||
| please check this site to verify that you have the latest version of zlib; | ||||
| otherwise get the latest version and check whether the problem still exists or | ||||
| not. | ||||
| 
 | ||||
| PLEASE read the zlib FAQ http://www.gzip.org/zlib/zlib_faq.html before asking | ||||
| for help. | ||||
| 
 | ||||
| Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997 | ||||
| issue of  Dr. Dobb's Journal; a copy of the article is available in | ||||
| http://dogma.net/markn/articles/zlibtool/zlibtool.htm | ||||
| 
 | ||||
| The changes made in version 1.2.1 are documented in the file ChangeLog. | ||||
| 
 | ||||
| Unsupported third party contributions are provided in directory "contrib". | ||||
| 
 | ||||
| A Java implementation of zlib is available in the Java Development Kit | ||||
| http://java.sun.com/j2se/1.4.2/docs/api/java/util/zip/package-summary.html | ||||
| See the zlib home page http://www.zlib.org for details. | ||||
| 
 | ||||
| A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is in the | ||||
| CPAN (Comprehensive Perl Archive Network) sites | ||||
| http://www.cpan.org/modules/by-module/Compress/ | ||||
| 
 | ||||
| A Python interface to zlib written by A.M. Kuchling <amk@magnet.com> is | ||||
| available in Python 1.5 and later versions, see | ||||
| http://www.python.org/doc/lib/module-zlib.html | ||||
| 
 | ||||
| A zlib binding for TCL written by Andreas Kupries <a.kupries@westend.com> is | ||||
| availlable at http://www.oche.de/~akupries/soft/trf/trf_zip.html | ||||
| 
 | ||||
| An experimental package to read and write files in .zip format, written on top | ||||
| of zlib by Gilles Vollant <info@winimage.com>, is available in the | ||||
| contrib/minizip directory of zlib. | ||||
| 
 | ||||
| 
 | ||||
| Notes for some targets: | ||||
| 
 | ||||
| - For Windows DLL versions, please see win32/DLL_FAQ.txt | ||||
| 
 | ||||
| - For 64-bit Irix, deflate.c must be compiled without any optimization. With | ||||
|   -O, one libpng test fails. The test works in 32 bit mode (with the -n32 | ||||
|   compiler flag). The compiler bug has been reported to SGI. | ||||
| 
 | ||||
| - zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works | ||||
|   when compiled with cc. | ||||
| 
 | ||||
| - On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is | ||||
|   necessary to get gzprintf working correctly. This is done by configure. | ||||
| 
 | ||||
| - zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with | ||||
|   other compilers. Use "make test" to check your compiler. | ||||
| 
 | ||||
| - gzdopen is not supported on RISCOS, BEOS and by some Mac compilers. | ||||
| 
 | ||||
| - For PalmOs, see http://palmzlib.sourceforge.net/ | ||||
| 
 | ||||
| - When building a shared, i.e. dynamic library on Mac OS X, the library must be | ||||
|   installed before testing (do "make install" before "make test"), since the | ||||
|   library location is specified in the library. | ||||
| 
 | ||||
| 
 | ||||
| Acknowledgments: | ||||
| 
 | ||||
|   The deflate format used by zlib was defined by Phil Katz. The deflate | ||||
|   and zlib specifications were written by L. Peter Deutsch. Thanks to all the | ||||
|   people who reported problems and suggested various improvements in zlib; | ||||
|   they are too numerous to cite here. | ||||
