"better" depends on how often such a trick is needed

*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
