Why is "updateDocSecurity()" is not running as documented?

[JoshMakesMaps]

updateDocSecurity() doesn't seem to be documented correctly and is not executing as expected in these scenarios:

• Running 

pdfDoc.updateDocSecurity("123456", "123456", "RC4", "OPEN")​

returns this error:

TypeError: updateDocSecurity() takes from 2 to 4 positional arguments but 5 were given​

• Running 

pdfDoc.updateDocSecurity("123456", "123456", "RC4")​

results in the process running forever.

• Running

pdfDoc.updateDocSecurity("", "", "RC4")​

results in the process running successfully.

Any idea what's going on?

python 3.0 documentation states with named parameters.

updateDocSecurity (new_master_password, {new_user_password}, {encryption})

or with your listing

pdfDoc.updateDocSecurity(new_master_password="123456",
                         new_user_password="654321",
                         encryption="RC4")

I suspect if the new user and master password are the same it will spin.

Change the first 2 parameters to suit.

Your first example failed because there is no 4th parameter (eg "OPEN" )

[JoshMakesMaps]

I tried it with the four parameters in the first example because that's how I saw in the example block on the documentation page. But yeah probably doesn't need that perimeter at all.

I have tried different variations of the passwords, also excluding only the master password or excluding only the user password. I still get the tool spinning forever.

[DanPatterson]

Using named parameters, as in my example, ensures that you have the correct parameter names.

The first parameter is required and must be known.

The second parameter is optional and its default is None.

If it is spinning, check your first parameter

[JoshMakesMaps]

It's still spinning forever after adjusting the script:

# Update PDF security.
            pdfDoc.updateDocSecurity(new_master_password="password123")

 and

# Update PDF security.
            pdfDoc.updateDocSecurity("password123")
