I think you need to put the redirection after the <<EOF, like
Code:
tr 'a-zA-Z' 'n-za-mN-ZA-M' <<EOF_EOF >$FIFO

But, what's your system? On linux you can usually do sh /dev/stdin and skip the fifo step entirely, like
Code:
tr 'a-zA-Z' 'n-za-mN-ZA-M' <<EOF_EOF | sh /dev/stdin

or even just
Code:
tr 'a-zA-Z' 'n-za-mN-ZA-M' <<EOF_EOF | sh

If you want to upgrade to real encryption, you can use
Code:
openssl enc -aes-256-cbc -a | openssl enc -base64 -a

to turn code into ASCII ciphertext and
Code:
openssl enc -d -base64 -a | openssl enc -d -aes-256-cbc -a

to turn ciphertext back into real text. The AES encryption/decryption part will ask you for a password in a secure manner.
