You absolutely need not to apologize. The answer of Hans Hagen was quite =
sufficient for me and=20
\def\SHA#1{\directlua{tex.sprint(sha2.hash256([=3D=3D=3D[#1]=3D=3D=3D]))}}=

was all I needed. I know Hans from ages ago and he knows what I need in =
cases like this.

Alas, wikifying is not my thing.
