Encrypted shell script is showing in plain text while executing

I run a encrypted shell script through crontab, while checking for process of script through ps -ef | grep script_name it is showing process along with script code in plain text

# ps -ef | grep test_script.x

#!/bin/bash if [ `echo $?` == 0 ]; then echo "This is my test script"  apt-get update else echo "This is end test script" fi sleep 3    ./test_script.x
