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 setPasswordproperty;
• Create Signature object and call any method.

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

LoadOptions loadOptions = new LoadOptions();
loadOptions.setPassword("1234567890");

// pass the load options with the password to the Signature constructor
Signature signature = new Signature("sampleProtected.pdf", loadOptions);
try {
    QrCodeSignOptions options = new QrCodeSignOptions("JohnSmith");
    options.setEncodeType(QrCodeTypes.QR);
    options.setLeft(100);
    options.setTop(100);

    // sign document to file
    signature.sign("signedProtected.pdf", options);
} finally {
    signature.dispose();
}
