Examples
Shows how to use specify PDF encryption details while saving a project as PDF file.
var project = new Project(DataDir + "CreateProject2.mpp");

// lets specify encryption details  
var encryptionDetails = new PdfEncryptionDetails(
    // specify user password
    "userPassword", 
    // specify owner password
    "ownerPassword", 
    // specify encryption algorithm
    PdfEncryptionAlgorithm.RC4_128);

// specify permissions
encryptionDetails.Permissions = PdfPermissions.ModifyContents | PdfPermissions.ModifyAnnotations;

// show user and owner passwords
Console.WriteLine("User Password: " + encryptionDetails.UserPassword);
Console.WriteLine("Owner Password: " + encryptionDetails.OwnerPassword);
// show encryption mode: RC4_40 or RC4_128
Console.WriteLine("Encryption Algorithm: " + encryptionDetails.EncryptionAlgorithm);
Console.WriteLine("Permissions: " + encryptionDetails.Permissions);

var options = new PdfSaveOptions
{
    EncryptionDetails = encryptionDetails
};

// save the project with specified encryption details
project.Save(OutDir + "WorkWithPdfEncryptionDetails_out.pdf", options);
