Protect PDF form without password

[Saher Naji]

Hello,

Is there a way to Protect a pdf form witout Password?

I encrypted it with a certificate, but it's also asking password for opening the file!

all I need is a very strong encryption without asking for password from the end user, but at the same time the user can fill in the form, and click on submit button, ... etc. Also I don't want the encryption to affect the javascript codes.

Best Regards,

[Bernd Alheit]

How have you added the certificate security?

Hi @Bernd Alheit

Thanks for reply

This is how I added the certificate security, watch this video please,

As for the used certificate, it contains Password, because there is not way to create a certificate without password

what I'm looking for is to protect the document, so the end user can not access to the fillable fields and change or delete or edit the JavaScript codes.

So it will be protected from editing, not from (opening and editing)

For the use of certificate security you need the public key of users certificate.

Why doesn't you use password security without open password?

Because any user can use any free tool to unlock the file, I just used for example smallpdf . com, and it removed the restrict protections in 1 second.

What do you want to protect it FROM, exactly? Please be detailed.

Hi @Test Screen Name
Thanks for reply
It will be protected from editing, not from (opening and editing), and the end user can fill out the form and submit it, but I don't want him to control the fillable fields by modifying their properties, deleting some of them or seeing the codes, (which may sometimes contain answers to surveys, or exams)

Hello,

Is there any update here?

[Bernd Alheit]

You can use certificate security with the public key of the user.
