Many thanks for your reply, Max.
This is exactly what I needed.

I think the following function is just fine for me:
\startbuffer[test]
just a test
\stopbuffer
\starttext
\startluacode
require("util-sha")
function document.sha512buffer(buffer)
return utilities.sha2.hash512(buffers.raw(buffer))
end
\stopluacode
\def\shabuffer#1
{\cldcontext{document.sha512buffer("#1")}}
\shabuffer{test}
\stoptext
Many thanks for your help again,
Pablo
