What can replace xxd in FreeBSD?

Question

linux

It is very necessary to have the xxd binary in fryaha. Or ... not xxd, but an analogue.
and here I can’t find the source code ... maybe someone has it?
even a vector of direction of thinking will do.
ps. necessary in order to make pfsense work https://github.com/gheift/letsencrypt.sh. this is by far the most concise implementation I know of.
