Took this from
a book:
Pick a number, I usually use 5 or 6,
Then, write/type/etc. your message like this:
Idkwha
ti'mtr
yingto
typeLo
Lwut?!
Only the number you chose of letters in that line.
Then, take the vertical columns and put them in order, horizontally. It comes out like this:
ItytL - diiyw - k'npu - kmnet - httL? - aroo!
Translation:
"Idk what I'm trying to type LoLwut?!"
Btw,
tplus - hisss - icIth - sf'to - tamnl - oijae
I'm offering the same reward Riot did if you decode it.
Maybe, probably not....
