    ----
Can anyone help me in identifying the algorithm used to decrypt this cipher text or finding the key:

Litrutisfgsofnaeeieoitdt

I've tried caesar cipher but that is not it. The best i got was from monoalphabetic technique. It was :

FINDONITERTHEWASSISHINGN

But cant decide on how to find out the key. Any suggestions?

The key for this would be 5

Hey Sniper Wolf,
I understand that you used are saying the key is 5.
Are you suggesting that it you are using Ceaser Cipher to decrypt the message?
For me upon using Ceaser and shift of 5 I get:
HEPNQPEOBCOKBJWAAEAKEPZP
which obviously doesn't make sense.
Please shed some light...
Thanks in advance

key should be 6, right?A simple "Columnar transposition"
