What do you mean with "greater string lengths"? MD5 adds the
length of the message as a 64 bit value. But even if your message
is greater the 2^64 byte (don't think you have a disk big enough
to hold such a message) you can use MD5 (only the low-order 64
bits of the message size are appended). Read RFC1321 for more
information.

Here the source code for a very simple MD5 implementation
(correct only for a file size up to 2^61 bytes because it uses
a 64 bit bit-counter instead of a byte-counter). It is size
optimized (to embed it within a batch program) and therefore
slow. There is a faster (but bigger) assembler version from
Laura ( http://lf.1accesshost.com/TOOLS/TOOLS.HTM ).

The following batch generates a MD5 checksum for each file in the
two directories and then compares this two files. If you save _2.chk,
you can later check if somebody has modified your saved files.

usage: dircomp.bat dir1 dir2

When you execute this batch, the current directory must not be
one of the two directories which are compared, because temporary
files are generated in the current directory. The temporary
files are not deleted, so you can see what happens in the batch.
To use this batch in DOS 6, you have to remove the " " from the
filenames. Source code for the two programs see older postings.

Here is a solution with the MD5 algorithm from RSA (see RFC 1321):

usage: login passwd

To add a new user, enter: login passwd user

If it is a 16 bit program, then maybe reading the file is the most
time consuming part. Laura has write a pretty fast 16 bit com
program ( http://lf.8k.com/TOOLS/TOOLS.HTM ). I'm more interested
in a small than a fast program (to include it in a batch file for
testing for file copy errors):

If you do a compare after you have copied the files, I suppose
Windows compares it with the version in the disk cache and don't
read it again from the USB device. So better disconnect an reconnect
the USB device before the compare. But if the file on the USB device
is corrupted, then the compare doesn't give you an error, it simple
compares two identical but corrupted files. So better generate
md5 checksums for the files before copying them to the USB device
and store this checksums also on the USB device. After you
copied the files from the USB device, recreate the checksums and
compare them with ones stored on the USB device. You can also
zip all the files into one zip file before copying them to the
USB device. The unzip program will recognize if the zip file
is corrupted.

If you can't use an external md5 program, you can include a
small (but slow) md5 program within your batch file:

What do you mean with "greater string lengths"? MD5 adds the
length of the message as a 64 bit value. But even if your message
is greater the 2^64 byte (don't think you have a disk big enough
to hold such a message) you can use MD5 (only the low-order 64
bits of the message size are appended). Read RFC1321 for more
information.

Here the source code for a very simple MD5 implementation
(correct only for a file size up to 2^61 bytes because it uses
a 64 bit bit-counter instead of a byte-counter). It is size
optimized (to embed it within a batch program) and therefore
slow. There is a faster (but bigger) assembler version from
Laura ( http://lf.1accesshost.com/TOOLS/TOOLS.HTM ).
