Most languages can do this (execute external programs).
Even a simple shell script run from cron...
cd $INPUT_DIR
ls | while read FILE
do
openssl_cmd1 $FILE $FILE.crypted
openssl_cmd2 $FILE.crypted
...
mv $FILE.crypted $OUTPUT_DIR/
rm -f $FILE
done
Copy/paste and adapt for the reverse.
It depends on the level of sophistication you want...
