Examples

The following sample code shows how the security manager can be instantiated and security settings customized:

Copy

// load the pdf document using the advanced security manager
PdfSecurityManager security = new PdfSecurityManager();
security.Load(file);

// encryption algorithm and key length
security.EncryptionAlgorithm = PdfEncryptionAlgorithm.AES;
security.EncryptionKeySize = PdfEncryptionKeySize.EncryptKey256Bit;

// set document passwords
security.OwnerPassword = "test1";
security.UserPassword = "test2";

//set document permissions
security.CanAssembleDocument = false;
security.CanCopyContent = true;
security.CanEditAnnotations = true;
security.CanEditContent = true;
security.CanFillFields = true;
security.CanPrint = true;

// add the digital signature
security.Sign(certFile, "selectpdf");

// save pdf document
security.Save(Response, false, "Sample.pdf");

// close pdf document
security.Close();

' load the pdf document using the advanced security manager
Dim security As New PdfSecurityManager()
security.Load(file)

' encryption algorithm and key length
security.EncryptionAlgorithm = PdfEncryptionAlgorithm.AES
security.EncryptionKeySize = PdfEncryptionKeySize.EncryptKey256Bit

' set document passwords
security.OwnerPassword = "test1"
security.UserPassword = "test2"

'set document permissions
security.CanAssembleDocument = False
security.CanCopyContent = True
security.CanEditAnnotations = True
security.CanEditContent = True
security.CanFillFields = True
security.CanPrint = True

' add the digital signature
security.Sign(certFile, "selectpdf")

' save pdf document
security.Save(Response, False, "Sample.pdf")

' close pdf document
security.Close()
