A probably quick and dirty « solution », which consists in inserting a \discretionary node between each digit using some lua code. There are mostly likely better solutions for this.
Joseph

\startluacode

function sha(s)
   local out = {}
   for i = 1, s:len() do
      out[#out + 1] = s:sub(i, i)
   end
   context(table.concat(out, '\\discretionary{_}{}{}'))
end

\stopluacode

\starttext
% \hsize\zeropoint
\hyphenation

Objet :[NTG-context] how to hyphenate SHA512?

Dear list,

I have the following sample:

    \starttext
    \hsize\zeropoint
    hyphenation

    8b2f3c087046c3943ace0dc4f958ef2138e58a51b40eef6fab6fa1aeb845cc25%
    7a410ab1b914bc399b4293f31c76fc2c73e5be5ea4d329f9e6820984688efec2
    \stoptext

I plan to use underscore hyphenation. How can I get the SHA512 string
hyphenated in any of its points?

Many thanks for your help,

Pablo
