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.
// 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();
}
// 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();
// Create secure object

// Decrypt input file

iReturnValue = 1;
goto cleanup;
}
// Cleanup
PdfSecureClose(pSecure);
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.
// Create secure object
using (Secure secure = new Secure())
{
// Open input file
if (!secure.Open(inputPath, ""))
