how to 'decrypt' "od -tx1 /dev/input/event4"

[Sam Sebastian]

i understand that this is the raw output for the devices in linux and the
output looks like hex??? i really have no idea but i wanted to know if
there was anyway to see what was going on (this the raw output from the
keyboard) and from what i have read it gives output for the depression of
the key, the key and when you let off the key,

0002740 4b 78 30 4f eb 48 09 00 01 00 1f 00 01 00 00 00
0002760 4b 78 30 4f ee 48 09 00 00 00 00 00 00 00 00 00
0003000 4b 78 30 4f d8 55 0a 00 04 00 04 00 1f 00 00 00
0003020 4b 78 30 4f e9 55 0a 00 01 00 1f 00 00 00 00 00
0003040 4b 78 30 4f ed 55 0a 00 00 00 00 00 00 00 00 00

this is the output that i get when i press the button "s" once (for as
little as possible)

Thanks for your help!

PS
I am NOT doing this for keylogging purposes, i have asked questions like
this on forums and usually get responses that i don't need to know how to
do this except for keyloggers
