Dear dr. van der Meer,
it is my fault since Hans explained this before (to me).
Here you have the minimal sample:
\ctxlua{require("util-sha")}
\def\shatwo#1{%
\cldcontext{utilities.sha2.hash256("#1")}}
\def\shafive#1{%
\cldcontext{utilities.sha2.hash512("#1")}}
\def\shatwofile#1{%
\cldcontext{utilities.sha2.hash256(io.loaddata("#1"))}}
\def\shafivefile#1{%
\cldcontext{utilities.sha2.hash512(io.loaddata("#1"))}}
\starttext
\def\testtext{abc}
\def\testfile{xml-mkiv.pdf}
\shatwo{\testtext}\\
\shafive{\testtext}
\shatwofile{\testfile}\\
\shafivefile{\testfile}
\stoptext
Would you be so kind to add it to the wiki?
I hope it may help,
Pablo
