Can anyone translate this phrase for me?

"Nithodess'sh ni ndi nijdout hit       Ndi niidee'sh nit"

I assume this line is in so called 'navajo code talker language'
however going through the dictionary of this language i could not
identify any of the words you used

However if i am wrong there is the problem the alphabet you are using
, the navajo alphabet has different letters
see an example here

and written out phonetically would make it almost impossible to
translate without a reference unless of coure you happen to stumble
onto a native speaker of Navaho on this board
