Now let s look at another problem that might arise. Suppose somebody sends you a signed contract. He has used a private key that is still valid, and you re sure that the document you ve received is genuine. However, at some point the author of the document regrets what he s written. By resetting the clock on his computer, he could create a new document with a new digital signature that is as valid as the first one. This way, you could end up with two documents signed with the same private key at almost the same time, but with slightly different content. How can anybody know which document is more genuine

This problem can be solved by involving a third party: a timestamping authority (TSA). The TSA will take the hash of the document and concatenate a timestamp to it. This is

private StreamConnectionNotifier createNotifier()throws IOException { return (StreamConnectionNotifier) Connector.open("serversocket://:4444", Connector.READ_WRITE, true); }

done on a timestamp server that is contacted during the signing process. The timestamp server will return a hash that is signed using the private key of the TSA. Figure 12.9 shows a PDF with a timestamped signature. In previous examples and screen shots, the signature panel informed you that the Signature date/time are from the clock on the signer s computer. Now it says: Signature is timestamped. You can also check the certificate of the TSA in the signature properties. That solves the potential problem of antedated documents. The next listing can be used to add a timestamp (if withTS is true) and to check the revocation status of the certificate with OCSP (if withOCSP is true).

In some implementations of the Generic Connection Framework it is necessary to specify the IP address rather than the domain name.

In this example, you use the PdfSignature dictionary to create a detached PKCS#7 signature, as opposed to PKCS#7 signatures where the data is encapsulated in the digest. Before you preclose the appearance, you also need to estimate the length of the signature s content.

You can also place a border around the entire page or multiple pages. This is handy if the text on a page may change. You can add or remove text without affecting the border of the page. To add a page border, click Format Borders and Shading. Open the Page Border tab, the options of which are shown in Figure 3-10. Specifying options for a page border is similar to specifying options for a border around text or a paragraph. There are two exceptions.
