People just need to learn to count in HEX.
From a game I'm translating (where I have to write the text in hex):
a1022c02430243024602c402c502a10246024e02c502280249022c02c502600246024c026d01
Translates to:
And I can write that very quickly.
Btw, ignore my comment on 256bit... it's 128bit. I was thinking every character was a byte instead of every two characters. Oops.
