How to send passphrase to gpg with symetric encryption?

[5468696A6D656E]

This might be the solution:

echo 1234   >1
echo "1234" >2
echo "1234">3
echo 1234>4

will all give different files in dos, (tested on win98 dos, compared
the output with a hexeditor) where unix and linux will trim
the echo, dos won't do that.

So your command should be: 
"echo 1234| gpg etc"
instead of 
"echo 1234 | gpg etc"

(hope i helped you get rid of the more insecure situation)
