Script to unreadable/unwritable script

Hello all.
Sorry for random question and my English.

I have made project I want it to share with my colleagues but I don't want them to read or change my scripts. So my question is "Is there a way to convert Scripts into unreadable/unwritable script?"

Thanks in advance!
