Execute shell script which is encrypted with openssl enc

I have a bash script which I need to encrypt(Run the script without anybody seeing the code.).

I have tried encrypting with command openssl enc -e -aes-256-cbc -a -in test.sh > testing.

I can execute the script with command:

openssl enc -e -aes-256-cbc -a -in testing -pass pass:<password> | sh -

But my script needs arguments as well, how to pass arguments to the encrypted script?

Original execution method: sh test.sh 1 a 23

How to execute encrypted script with arguments "1 a 23"?

Any help would be appreciated. Thanks in advance.

Solution

  • You can explicitly tell sh to read the commands from stdin, and the specify the arguments:

    openssl ... | sh -s 1 a 23
