You are using the wrong code. That is indeed windows specific bindings. The openssl bindings are at the bottom of the page. Though you may want to pick up hexhash definition from the top section.

Specifically, I built libmd5.so using https://github.com/rdm/libmd5.so, copied it into the directory /home/ubuntu/bin/ and then used, from in J: md5raw=: '/home/ubuntu/bin/libmd5-64.so MD5String > l *c l'&(15!:0)@(; #) md5=: 3 :',tolower hfd a.i. 15!:1 (md5raw y),0 16 2' Now... since I need both 32 bit J (to parse xml using xml/sax - apparently that only works on 32 bit j602) and 64 bit J (to deal with more data than will fit in a 32 bit process), I'm having to have two copies of libmd5.so - one for each instance of J. But I can live with that. Thanks, -- Raul On Sat, Sep 6, 2014 at 11:23 AM, 'Pascal Jasmin' via Programming <programm...@jsoftware.com> wrote: > the code was tested at one point on mac.
