Just throwing this here in case it’s useful to someone else… I often come across binary in challenges that needs to be reversed, and don’t always have a quick tool available. Assuming you have Perl installed, it’s a straightforward conversion (this assumes 8 bit, zero-padded data):
echo 01000001 01000010 01000011 01000100 | perl -lape '$_=pack"(B8)*",@F'
Good hunting. 🙂
