I understand that in linux everything goes, but let's face it - hexdump wasn't made for that purpose.
Cough...
What? "hexdump" is excellent for creating an ASCII version array quickly of a pure binary file to work on before reconverting back to pure binary again.
However if hexdump is not good enough for you then go with Perl or Python. Python being probably the better of the two for this application...
EDIT:
hexdump creating /bin/bash into a 4+MB ASCII data file.
Not bad for speed eh!
It takes double that time to put it into an array format directly.
