Dear list, I have this minimal sample: \ctxlua{require("util-sha")} \def\sha#1{% \ctxlua{context(utilities.sha2.hash512("#1"))}} \startbuffer[text] hola \stopbuffer \starttext \sha{hola} \sha{\typebuffer[text]} \stoptext How can I get that both commands get the same sha512sum? Many thanks for your help, Pablo
