Can you programmatically add a password to a document? For example: After a user signs a document, a script adds a password and saves it as a new file.

Can you programmatically add a password to a document? For example: After a user signs a document, a script adds a password and saves it as a new file.

This way, after the user has signed the document, only people with the password can view it. I want to do this programmatically maybe with Javascript?

Thanks!
