the change produces some success. It turns out I had the wrong value for ALGid
(2nd param)
I get success with passing the CALG_ID value for SHA1, but SHA256 (32780) seems
to fail on my system
CryptCreateHash ({. a2) ; 32772 ; 0 ; 0 ; (m=. , _1) NB. SHA1 hash

I guess it should be
CryptCreateHash =: 'advapi32.dll CryptCreateHash i x i i i *x' & cd
CryptCreateHash ({.a); ALG_SID_SHA_256; 0 ; 0 ; (m=.,_1)
untested.
