DOS.MD5SUM)
''Note: the current Pacific C build of FreeDOS' md5sum doesn't match up with any other well-known md5 tool. You'll need to recompile with OpenWatcom or Turbo C++ instead. Or go to http://www.fourmilab.ch/md5/ (Win32 binary w/ src) and recompile that, or just download XSUM11?.ZIP (DOS .EXE, no src) from http://www.simtel.net/pub/pd/45640.shtml .
MD5SUM is a checksumming tool currently maintained by Blair Campbell. The latest release is v3.0 and its features are:
- MD5, SHA-256, CRC-32, and SHA-1 hashes
- LFN support
- Support for '/', '-', and the DOS switch character API for switches
- /C to check hashes instead of create
- Prints the full name, including path of every file hashed
- Supports binary and text mode
- /R to make hashes recursively
- Support for paths with '/' OR '\'
- Support for @file lists as input
- Compiler support for OpenWatcom, Pacific C (incompatible?), and Turbo C
Some planned/currently implemented but not released features are:
- CRC-16 checksums that check out with another checksummer
- Look into Blowfish and RMD-160
- A port to DJGPP
- Any other requested features may be looked in to
Some known problems that I would appreciate help with fixing are:
- MD5SUM in LFN and Recursive modes stops digesting after a certain amount of files
In order to use SHA-256 hashes, one must compile MD5SUM defining USE_SHA256, switch to the medium memory model, and link with the recommended amount of stack in the makefile.
MD5SUM version 3 is currently available at:
http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/util/file/MD5SUMS.zip (source)
http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/util/file/MD5SUMX.zip (binary)
Testers are greatly appreciated, and I would be particularly interested in knowing how it works on an 8086. MD5SUM has been tested on a 286 and apparently works well (with all features enabled, like LFN and SHA-1).
The following messages can be translated to aid MD5SUM's NLS.

0.0:Usage: MD5SUM [options] [/C [file]] | [file...]
0.1:Generates or checks MD5 Message Digests
0.2: /C check message digests (default is generate)
0.3: /[-]V enable or disable verbose mode (default is off)
0.4: /[-]L enable or disable LFN usage (default is enable if supported)
0.5: /[-]R[num] enable or diable recursing (default is off)
0.6: num is a number from 1 to 9 and limits recursion (default=4)
0.7: /[-]S same as /[-]R
0.8: /T read files in text mode
0.9: /B read files in binary mode (default; overrides /T)
0.10: /M[:|=]mode select the digest mode
0.11:The input for /C should be the list of message digests and file names
0.12:that is printed on stdout by this program when it generates digests.
0.13:The argument for /M should be a digest mode, which could possibly be SHA,
0.14:CRC32?, SHA256?, or MD5, depending on how MD5SUM was compiled.
