I am using gpg encryption to cat "file" to a pipe which has my passphrase in it to allow decryption to occur. I want to use Perl to do this below : 
cat file |gpg --option newfile oldfile

Here is a snippet: 
open (PASS, "+<$pass") or warn "was unable to open FH $!";
    for (;<PASS>;) {
        $gpgpass = $_;
    }

thank you!
