interleaving colons as a workaround
</context>
</ref>
=== Workaround with soft hyphens ===
As a workaround, a simpler way to break SHA sums in lines, but without any character would be (abusing both {{cmd|handletokens}} and {{cmd|softhyphen}}):
ef6fab6fa1aeb845cc257a410ab1b914bc399b4293f%
31c76fc2c73e5be5ea4d329f9e6820984688efec2}
\stopTEXpage
</context>
=== Another workaround interleaving colons ===
Another workaround that also helps to improve readability are interleaved colons every two characters. Of course you might change the number of chars without colons adding single dots to <code>str:match("..")</code>. Please, keep in mind that this will make line wrapping not easier in some places.
