How to decrypt Cryptcat (twofish) data?

I have some packets that are encrypted with Cryptcat tool and I want to decrypt them. I have the encryption password. I tried to use netcat with cryptcat, but every time I'm connecting from netcat to cryptcat and try to send something the connection closes. I tried the following: cryptcat -vv -k p@ssword -l -p 1337 > decryptedfile and from another terminal: cat encrypted | nc localhost 1337 When I hit enter the connection closes!
