+
+ This code is a modified version of crypting code in Infozip distribution
+
+ The encryption/decryption parts of this source code (as opposed to the
+ non-echoing password parts) were originally written in Europe. The
+ whole source package can be freely distributed, including from the USA.
+ (Prior to January 2000, re-export from the US was a violation of US law.)
+
+ This encryption code is a direct transcription of the algorithm from
+ Roger Schlafly, described by Phil Katz in the file appnote.txt. This
+ file (appnote.txt) is distributed with the PKZIP program (even in the
+ version without encryption capabilities).
+
+ If you don't need crypting in your application, just define symbols
+ NOCRYPT and NOUNCRYPT.
+
+ This code support the "Traditional PKWARE Encryption".
+
+ The new AES encryption added on Zip format by Winzip (see the page
+ http://www.winzip.com/aes_info.htm ) and PKWare PKZip 5.x Strong
+ Encryption is not supported.

+ Independent implementation of MD5 (RFC 1321).
+
+ This code implements the MD5 Algorithm defined in RFC 1321, whose
+ text is available at
+ http://www.ietf.org/rfc/rfc1321.txt
+ The code is derived from the text of the RFC, including the test suite
+ (section A.5) but excluding the rest of Appendix A. It does not include
+ any code or documentation that is identified in the RFC as being
+ copyrighted.
+
+ The original and principal author of md5.c is L. Peter Deutsch
+ <ghost@aladdin.com>. Other authors are noted in the change history
+ that follows (in reverse chronological order):
+
+ 2002-04-13 lpd Clarified derivation from RFC 1321; now handles byte order
+ either statically or dynamically; added missing #include <string.h>
+ in library.
+ 2002-03-11 lpd Corrected argument list for main(), and added int return
+ type, in test program and T value program.
+ 2002-02-21 lpd Added missing #include <stdio.h> in test program.
+ 2000-07-03 lpd Patched to eliminate warnings about "constant is
+ unsigned in ANSI C, signed in traditional"; made test program
+ self-checking.
+ 1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
+ 1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5).
+ 1999-05-03 lpd Original version.

+
+ A lot of thanks to Kaloz and juhosg from OpenWRT and Lennert Buytenhek from
+ marvell for helping me figure this one out. This code is based on bash
+ scripts wrote by Peter van Valderen so the real credit should go to him.
+
+ This program reads the provided parameter file and creates an image which can
+ be used to flash a Linksys WRT350N v2 from stock firmware.
+ The trick is to fill unused space in the bin file with random, so that the
+ resulting zip file passes the size check of the stock firmware.
+
+ The parameter file layout for an original Linksys firmware:
+ :kernel 0x001A0000 /path/to/uImage
+ :rootfs 0 /path/to/root.squashfs
+ :u-boot 0 /path/to/u-boot.bin
+
+ args:
+ 1 wrt350nv2.par parameter file describing the image layout
+ 2 wrt350nv2.img output file for linksys style image
+
+ An u-boot image inside the bin file is not necessary.
+ The version is not important.
+ The name of the bin file is not important.
+
+ Linksys assumes that no mtd will be used to its maximum, so the last 16 bytes
+ of the mtd are abused to define the length of the next mtd content (4 bytes for
+ size + 12 pad bytes).
+
+ At the end of "rootfs" additional 16 bytes are abused for some data and an
+ highly important eRcOmM identifier, so the last 32 bytes of "rootfs" are abused.
+
+ At the end of "u-boot" 128 bytes are abused for some data, a checksum and an
+ highly important sErCoMm identifier.
+
+
+ This program uses a special GNU scanf modifier to allocate
+ sufficient memory for a strings with unknown length.
+ See http://www.kernel.org/doc/man-pages/online/pages/man3/scanf.3.html#NOTES
+
+
+ To extract everything from a Linksys style firmware image see
+ https://forum.openwrt.org/viewtopic.php?pid=92928#p92928
