any data can be represented as a string of ones and zeros, but there are
many different convention for how to order and group such a thing.

the xxd tool will take any input and convert it to arbitrary forms.  for
ones and zeros, you can use -bits.  for example:

0 dkg at alice:~$ echo this is a test | xxd -bits
00000000: 01110100 01101000 01101001 01110011 00100000 01101001  this i
00000006: 01110011 00100000 01100001 00100000 01110100 01100101  s a te
0000000c: 01110011 01110100 00001010                             st.
0 dkg at alice:~$

you can use this technique on anything, including an OpenPGP signature.
