How to load password-protected document Leave feedback

GroupDocs.Signature supports processing documents that are protected with a password.

The following are the steps to work with password protected documents.

• Instantiate the LoadOptions object;
• Set password in LoadOptions the Password property;
• Create Signature object and call any method.

The following code sample shows how to process password protected documents.

LoadOptions loadOptions = new LoadOptions()
{
    Password = "1234567890"
};
using (Signature signature = new Signature("sampleProtected.pdf", loadOptions))
{
    QrCodeSignOptions options = new QrCodeSignOptions("JohnSmith")
    {
        EncodeType = QRCodeTypes.QR,
        Left = 100,
        Top = 100
    };
    // sign document to file
    signature.Sign("SignedSampleProtected", options);
}
