I tried your code at http://www.jsoftware.com/jwiki/PascalJasmin/SHA%201%2C%202%20and%20MD5%20for%20windows
sha256 hexhash 'The quick brown fox jumps over the lazy dog' |domain error: cd | CryptAcquireContext(aProv=.,_1);(<0);(<0);PROV_RSA_AES;CRYPT_VERIFYCONTEXT Meanwhile, what I have works for me. 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.
