Encryption

Decrypt a PDF document

Decrypt a PDF document. A password must be provided if the document requires a password to open. Create a new PDF document without encryption and full access permissions.

C# sample:

// Create secure object
using (Secure secure = new Secure())
{
    // Decrypt input file
    if (!secure.Open(inputPath, password))
        throw new Exception(String.Format("Input file {0} cannot be opened. " + 
            "{1} (ErrorCode: 0x{2:x}).", inputPath, secure.ErrorMessage, secure.ErrorCode));

    // Save file
    if (!secure.SaveAs(outputPath, "", "", PDFPermission.ePermNoEncryption, 0, "", ""))
        throw new Exception(String.Format("Unable to save document {0}. {1} (ErrorCode: 0x{2:x}).",
            outputPath, secure.ErrorMessage, secure.ErrorCode));

    // Cleanup
    secure.Close();
}

C# sample:

Java sample:

// Create secure object
secure = new Secure();

// Decrypt input file 
if (!secure.open(inputPath, password))
    throw new IOException(String.format("Input file %s cannot be opened. %s (ErrorCode: 0x%08x).", 
            inputPath, secure.getErrorMessage(), secure.getErrorCode()));

// Save file
if (!secure.saveAs(outputPath, "", "", NativeLibrary.PERMISSION.ePermNoEncryption, 0, "", ""))
    throw new IOException(String.format("Unable to save the document %s. %s (ErrorCode: 0x%08x).", 
            outputPath, secure.getErrorMessage(), secure.getErrorCode()));

// Cleanup
secure.close();

Encrypt a PDF document

Set a user and an owner password for the output document. If a user password is set, either of the passwords is required to open the output document. If the user password is an empty string, the document can be opened without a password. The user can print the document, but may not perform other actions, such as text extraction, unless he knows the owner password.

C# sample:

// Create secure object
using (Secure secure = new Secure())
{
    // Open input file
    if (!secure.Open(inputPath, ""))

            "{1} (ErrorCode: 0x{2:x}).", inputPath, secure.ErrorMessage, secure.ErrorCode));

    // enable encryption 
    secure.ForceEncryption = true;

    // Encrypt file
    if (!secure.SaveAs(outputPath, userPassword, ownerPassword, PDFPermission.ePermDigitalPrint | 
        PDFPermission.ePermPrint, 128, "V2", "V2"))
        throw new Exception(String.Format("Unable to encrypt document {0}. " +

Signing

Mass signing of PDF documents

Travers a directory and its subdirectories and add a signature to all existing PDF files. Speed up the signing process by means of parallel execution. Get all signed documents in the given output directory.

C# sample:

using (SessionPool pool = new SessionPool())
{
    List allTasks = new List();
    foreach (string inputPath in Directory.GetFiles(inputDir, "*.pdf", SearchOption.AllDirectories))

        string outputPath = inputPath.Replace(inputDir, outputDir);
        Directory.CreateDirectory(Path.GetDirectoryName(outputPath));

        // Start signing task
        Task t = Task.Factory.StartNew(() => Sign(pool, inputPath, outputPath, certificate));
        allTasks.Add(t);
    }

PAdES

Create PAdES-B-LTA signature on a PDF document

Upgrade a PDF document with a PAdES-B-T signature to a PDF document with a PAdES-B-LTA signature or enlarge the longevity of a document with an existing PAdES-B-LTA signature. Provided it is available, signature validation information is added for all signatures of the document and a new time-stamp is added. The validation information contains all public certificates of the signing certificate’s trust chain and the revocation data (OCSP or CRL) for all certificates that support revocation information.

In Memory

Sign PDF in memory

Read a PDF from a byte stream, sign it and return the result as byte stream. Use a Cryptographic Provider to access the certificate and to get the necessary cryptographic algorithms. For demonstration purpose, the PDF byte stream is created from file and the resulting byte stream is written back to a file.

// Create secure object

    // Open input file

    // Begin session with Windows Cryptographic Provider
    if (!secure.BeginSession(""))
        throw new Exception(String.Format("Unable to connect to Windows Cryptographic Provider. " +
            "{0} (ErrorCode: 0x{1:x}).", secure.ErrorMessage, secure.ErrorCode));

    // Create signature object
    using (Signature signature = new Signature())
    {
        signature.Name = certificate;
        secure.AddSignature(signature);

        // Save output buffer in-memory

        // Get output PDF as byte array
        byte[] outputBuffer = secure.GetPdf();
        if (outputBuffer == null)
