I need to be able to encrypt a PDF with a password.
This works as expected.

However, I need the XMP meta data to not be encrypted.
For example, in PDF-XChange Editor I can apply a passwort but define that the meta data should not be encrypted (see attachment).

As I see it, this is currently not possible wit Spire.PDF (for .Net or Android).

So, is it possible that you could add this feature?
And what would be an estimate when this would be available for .Net and for Android?

Thanks for your post.

Yes, we do not yet support encrypting all PDF document contents except metadata. We will consider adding it as a new feature to our upgrade list.
But I am sorry that we cannot give you an estimated implementation time at this moment. Anyway, once there is any good news, we will let you know immediately. Apologize for the inconvenience caused.
