How to get a random string of 32 hexadecimal digits through command line?

Question

I\'d like to put together a command that will print out a string of 32 hexadecimal digits. I\'ve got a Python script that works:

python -c \'import random ; prin         


        

Answer 1

Try:

xxd -u -l 16 -p /dev/urandom

Example output:

C298212CD8B55F2E193FFA16165E95E3

And to convert it back to binary:

echo -n C298212CD8B55F2E193FFA16165E95E3 | xxd -r -p
