I'm composing communication lyrics for client-server and what am I thinking about:

"authme username passord" (maybe encrytped)
"accept"
"get archive of H2O from 03.02.2005 to 20.12.2064"
transferring binary structure or "error descrtiption"

why I always need to do something like

0x0FA52FD + CRC
0x0D34423 + CRC
...

I can see some secure reasons but I think it's not the real reason so why I can't use strings in client-server communication?
