This was the code given to you by Bruno Toniutti, and I think it'd be nice to make a reference here, anyway he gave you the answer later on too:
>the encryption is working good but decryption wont..
you must use a rotation of 13 positions (a (position 1) becomes (1 + 13) =
n etc.) for an alphabet of 26 characters. Thus this algo works to encrypt
and decrypt.
