The quote tip is really good. It also works for octal as well as hexadecimal.
I'm still refining an answer to:
Convert clear text into binary
Currently I'm converting each character to octal using "printf" then converting the octal character to binary using "bc". It is chronically inefficient ... but it works.
The only reason to go via octal rather than hexadecimal is to create a symmetrical reverse translation path back to the original characters to prove the conversion.
