How to integrate support for securing a property in my Java application?

 
import com.sun.jna.Library;
import com.sun.jna.Native;
import com.sun.jna.WString;
private interface SecurePropDLL extends Library {
    // Match the calling convention of the "GetRevealedTextLength" exported function
    int GetRevealedTextLength(WString aSecuredText);
    
    // Match the calling convention of the "RevealText" exported function
    void RevealText(WString aSecuredText, char[] aPlainTextBuffer, int aBufferLength);
}
…
// Load the dll file
SecurePropDLL dll = Native.loadLibrary(“SecureProp.dll”, SecurePropDLL.class);
…
      

 
// Load the dll file
SecurePropDLL dll = Native.loadLibrary(kDllName, SecurePropDLL.class);
// Load the properties from the ini file
ArrayList<SecuredProperty> properties = new ArrayList<SecuredProperty>();
LoadPropertiesFromIni(properties);
if (properties.size() == 0)
    return;
//------------------------------------------------------------------------------------------
// Use the SecureProp library
//------------------------------------------------------------------------------------------
for (SecuredProperty property : properties) {
    WString propValue = new WString(property.mValue);
    
    //------------------------------------------------------------------------------------------
    // Exported function call
    // Reveal the secured text and return its length
    //------------------------------------------------------------------------------------------
    int textLength = dll.GetRevealedTextLength(propValue);
    
    // Allocate a buffer of wide characters with the length: textLength + 1
    // We need to add 1 in order to provide space for the null terminator
    char[] textBuffer = new char[++textLength];
    //------------------------------------------------------------------------------------------
    // Exported function call
    // Reveal the secured text and store the result in the provided buffer
    //------------------------------------------------------------------------------------------
    dll.RevealText(propValue, textBuffer, textLength);
  
    // Output the revealed text
    System.out.println(property.mName + " = " + new String(textBuffer));
}
