That function is calling a function from another object you clearly don't
have in scope ( forge .md.sha1.create() ) so wscript.shell won't be able to run it
unless you provide all the source.

Better just use vfpencryption.fll:

set library to vfpencryption71 additive
chash =  hash(m.txt,1) 
cHash64 = strconv(m.cHash,13)

Note:
vfpencryption71.fll needs msvcr71.dll & msvcp71.dll
you can download all three from :
