Removing PDF password protection, knowing the password

I have a bunch of pdf's I want to remove passwords from. Note that I know the password, so no need for brute forcing. I am working on a mac, so I would like to make an app to remove those passwords.

I have seen apps like wondershare's pdf password remover, so I know it is possible.

Is there a solution/library in the obj-c environment to remove passwords from PDF's?

I think this would work for you. Both answers seem valid, I personally would opt for the second one.

do shell script "pdftk secured.pdf input_pw foopass output unsecured.pdf"
