& Verifications.
Certifying a PDF (Available in Business Only)
Only the author can certify his/her own PDF documents. The author can specify what
changes can be made to the file after certifying. Whenever approved changes are made,
the certificate remains valid. If a reader tries to make changes you haven't allowed, the
certificate is invalidated and any subsequent users will be notified that the document was
tampered with.
Add a time stamp to digital signatures and documents
Time stamps are used to specify the date and time you signed a document. A trusted time
stamp proves that the contents of your PDFs existed at a point-in-time and have not
changed since then. Foxit PhantomPDF allows you to add a trusted time stamp to digital
signatures or documents.
Before adding a time stamp to digital signatures or documents, you need to configure a
default time stamp server. Go to File > Preferences > Time Stamp Servers, and set a
default time stamp server. You can then sign the document by placing the digital signature,
or by clicking Protect > Time Stamp Document to add a time stamp signature to the
document. You need to add the time stamp server into the trusted certificate list so the
properties of digital signatures will display the date/time of the time stamp server when
the document was signed.
To add a trusted time stamp server to the Trusted Certificates list, click Timestamp
Properties in the lower left corner of the Signature Properties dialog box. In the pop-up
Timestamp Properties box, click Add to Trusted Certificates. If a time stamp signature
was added in the document, you can right-click the timestamp signature in the Digital
Signature panel and choose Show Signature Properties. In the pop-up Signature
Properties dialog box, click Add to Trusted Certificates.
