With \directlua{context(md5.hex([===[#1]===]))} I can calculate the MD5 checksum. I thought there was another call for the calculation of the SHA checksum, but I could not find it in the documentation or on the context garden. Where to look?

have a look at l-sha.lua ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

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
