Unverified Signatures

Using this feature is dangerous!

PDF forms can bear a digital signature. Such a signature confirms that the PDF that it's been created by the author (and not someone else).

However, ngx-extended-pdf-viewer does not verify the validity of the signature. The signature is displayed without any hint it's faulty. So use this feature carefully! Do not show the signature unless you're 100% sure it's valid. Otherwise, users may draw wrong conclusions.

To activate signatures, you must set the attribute showUnverifiedSignatures.
