Sample_Other.java

The following code sample illustrates how to encrypt data.

import java.io.File;
import java.io.FileOutputStream;

import com.eruces.teagent.TEAgentConnection;
import com.eruces.teagent.TECipher;
import com.eruces.teagent.TECipherOutputStream;
import com.eruces.teagent.TEKey;

public class Sample_Other {
    
    private static TEAgentConnection conn;
    private static byte[] ttag;
    
    public static void writeBMP_encrypted(String strFile, byte[] header, byte[] data) {

        FileOutputStream fos = null;
        TECipherOutputStream cos = null;
        
        try {
            TEKey teKey = new TEKey();
            teKey.attachConnection(conn);
            TECipher teCipher = teKey.exportKey(new byte[0]);
            
            ttag = teCipher.getRawHiddenLink();
            
            fos = new FileOutputStream(new File(strFile));
            cos = new TECipherOutputStream(fos, teCipher);
            
            fos.write(header);
            
            int place = 0;
            
            while (place < data.length) {
                if (place + 64 < data.length) {
                    cos.write(data, place, 64);
                    place += 64;
                }
                else {
                    cos.write(data, place, data.length - place);
                    place += data.length;
                }
            }
            
            cos.close();
            fos.close();
            teKey.detachConnection();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
