The following code demonstrates how to unseal a sealed file using the unseal
method. The content to unseal can be provided as any type of java.io.InputStream; this example uses a file input stream. The sample code writes the resulting stream out to a file.
Example 7-6
import static oracle.irm.engine.content.sealing.SealingOperationsInstance.unseal; import java.io.FileInputStream; import java.io.FileOutputStream; import java.net.Authenticator; import java.net.PasswordAuthentication; public class UnsealFile { public static void main(String[] args) throws Exception { // The user name and password are provided on the command line. In a production // system these details should be provided in a more secure manner, such // as prompting from the console, or reading from a secure source. final String username = args[0]; final String password = args[1]; // Configure an authenticator to provide the credentials for any network access Authenticator.setDefault(new Authenticator() { @Override protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(username, password.toCharArray()); } }); // The file to unseal String sealedFilename = args[2]; // The unsealed file name String unsealedFilename = args[3]; // Sealed file input stream FileInputStream inputStream = new FileInputStream(sealedFilename); // Unsealed file output stream FileOutputStream outputStream = new FileOutputStream(unsealedFilename); // Unseal the sealed file unseal(inputStream, outputStream); // Close the file streams inputStream.close(); outputStream.close(); } }
