Win32 native md5sum, sha1sum, sha256sum etc.

I have compiled native (no Cygwin, no other dlls) Windows versions of md5sum.exe, sha1sum.exe, sha224sum.exe, sha256sum.exe, sha384sum.exe and sha512sum.exe. Download binaries here, and source (as required by GPL) here. If you want to compile them yourself (with MinGW and MSYS), just delete error-causing lines from configure and makefiles until you succeed.

Update 2008/05/26: I've compiled new binaries from coreutils-6.11, download them here.

Gosh, thanks. Windows is so unusable. I try to avoid it, but sometimes I get stuck with it and people like you bail me out. Can you imagine an operating system which doesn't ship with command line checksumming software? How broque.

I don't think your port works corrctly under all circumstances, I tried it on my download of the Fedora Core 9 DVD, and it said the check failed, whereas this port: ftp://ftp.gnupg.org/gcrypt/binary/sha1sum.exe produced the correct hash (although it took a long time and loads of memory!)

This sha1sum copy worked just fine for my Fedora 9 DVD ISO. Of course it used about 400mb of RAM, but with 3GB, I'm not that picky.

Thank you for the info. I will check this. Maybe it's related to the size of the image, which is larger than 2 GB. Anyway, it's not a port, I just simply compiled the software from the original sources.

It calculates the correct checksum for me on Windows XP SP3:

F:\>gpgsha1\sha1sum Fedora-9-i386-DVD.iso

at least sha256sum fails to handle unix line endings. .digests file created in linux and containing output of linux's sha256sum cannot be used by this windows version. sha256sum.exe -c digests-file: first hash on the list checks out fine but rest of hashes fail.

ofcourse running sha256sum.exe on these datafiles themselves yields correct hashes.

I have some issues when running this program on a 64bit environment.

For test purposes I have two "naked" Windows Server 2003 R2 installations. One 32bit and one 64bit.

When I try to do a sha512 on the 32bit machine it works fine with all files eg: c:\windows\system32\wuauclt.exe

When the exact same command is passed on the 64bit machine sha512sum fails.

c:\tools\sha512sum.exe: c:\WINDOWS\system32\wuauclt.exe: No such file or directo
ry

The permissions seems identical.
I can execute the wuauclt file.
I can copy the wuauclt file.
7-zip have no problem reading the file and creating an archive with it in.

Any ideas what could be wrong?

I believe I found the problem I experience with files in the system32 catalog.

It is due to folderredirection in 64bit systems. It is described here:

http://wredsys.wordpress.com/2011/02/28/how-to-suppress-system32-folder-redirection-to-syswow64-folder-sysnative/

Would be sweet with a 64bit version of these utils :-)

If you're still around. What compiler did you use and settings? thanks!

#6 Adam on 2012-07-08 07:27 (Reply)

I've used the then current MinGW/MSys compiler (http://www.mingw.org/). I don't remember the exact settings, but my favorite is -O2 -s -Wall.
