I created a self-signed digital ID for both signature end data encryption.
Then I created a pdf form by using livecycle and put it on our website, and after users fill it in, they will click submit by email to submit the data.
I tried to create a self-signed digital ID.- that also does data encryption. Then I did a test to fill the form, send by email. I suppose it has encrypted the attached PDF form, but I can open it just like regular form without encryption. How can I know if it is encrypted or not?
