Hi,
I have been playing with the signing example of PDF Box 2.0.3.
I would like to apply a certification signature (
https://helpx.adobe.com/acrobat/kb/certificate-signatures.html )
How could I do ? Do you have any example ?
Thanks,
Jonathan.
There is no example, but the test TestPublicKeyEncryption.java from the
source download should help too.
https://svn.apache.org/viewvc/pdfbox/trunk/pdfbox/src/test/java/org/apache/pdfbox/encryption/TestPublicKeyEncryption.java?view=markup
There's also a segment in the Encrypt command line tool:
if( certFile != null )
{
PublicKeyProtectionPolicy ppp = new
PublicKeyProtectionPolicy();
PublicKeyRecipient recip = new
PublicKeyRecipient();
recip.setPermission(ap);
CertificateFactory cf =
CertificateFactory.getInstance("X.509");
InputStream inStream = null;
try
{
inStream = new FileInputStream(certFile);
X509Certificate certificate =
(X509Certificate)cf.generateCertificate(inStream);
recip.setX509(certificate);
}
finally
{
if (inStream != null)
{
inStream.close();
}
}
ppp.addRecipient(recip);
ppp.setEncryptionKeyLength(keyLength);
document.protect(ppp);
}
else
{
.....
}
document.save( outfile );
}
