C# and VB.NET example code to embed a binary file into XML, and extract. Can optionally encrypt/decrypt with 128-bit AES encryption, and zip/unzip (using the .zip deflate algorithm).

Chilkat.Xml xml = new Chilkat.Xml();

bool success;

xml.Tag = "test";

bool zipContent;
zipContent = true;
//  If desired, the content can be 128-bit AES encrypted:
bool encryptContent;
encryptContent = false;
string encryptPassword;
encryptPassword = "";

success = xml.SetBinaryContentFromFile("chilkat.bmp",zipContent,encryptContent,encryptPassword);
if (success != true) {
    MessageBox.Show(xml.LastErrorText);
    return;
}

//  Display the XML:
textBox1.Text += xml.GetXml() + "\r\n";

//  Extract the binary content from XML:
bool unzipContent;
unzipContent = true;
bool decryptContent;
decryptContent = false;
string decryptPassword;
decryptPassword = "";
success = xml.SaveBinaryContent("out.bmp",unzipContent,decryptContent,decryptPassword);
if (success != true) {
    MessageBox.Show(xml.LastErrorText);
    return;
}

MessageBox.Show("Success!");
