Something seems to be wrong with the library:

For example

$echo -n "test" | md5sum 098f6bcd4621d373cade4e832627b4f6  -

but

print(md5.sumhexa("test")) gives

0944483cd90a293923c8244520132de1

strange, as on my machine (vista) it gives

098f6bcd4621d373cade4e832627b4f6

Same here on WinXP with luatex beta-0.40.6-2009110118 & beta-0.46.0-2009112716.

I don't know what gives. I did test Reinhard's installer on the same machine and with the same binaries and it failed on checksums back then.

seems to be a 32/64 bit issue. After sprinkling the md5.c code with 32 bit MASKs (see diff) luatex indeed gives the correct 098f6bcd4621d373cade4e832627b4f6 on an x86_64 AMD debian Linux PC. Unclear which MASK made it, but i guess it's in the rotate(). Regards, Hartmut
