triple des file encryption and decryption

Thanks bro. I do the same. jar file added to project and build. Now showing
"can not find symbol." Method encodeBase64(..)

private String _encrypt(String message, String secretKey) throws Exception {

MessageDigest md = MessageDigest.getInstance("SHA-1");
byte[] digestOfPassword = md.digest(secretKey.getBytes("utf-8"));
byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);

SecretKey key = new SecretKeySpec(keyBytes, "DESede");
Cipher cipher = Cipher.getInstance("DESede");
cipher.init(Cipher.ENCRYPT_MODE, key);

byte[] plainTextBytes = message.getBytes("utf-8");
byte[] buf = cipher.doFinal(plainTextBytes);
byte[] base64Bytes = Base64.encodeBase64(buf);
// byte [] base64Bytes = Base64.;
String base64EncryptedString = new String(base64Bytes);

return base64EncryptedString;
}

private String _decrypt(String encryptedText, String secretKey) throws Exception {

byte[] message = Base64.decodeBase64(encryptedText.getBytes("utf-8"));

MessageDigest md = MessageDigest.getInstance("SHA-1");
byte[] digestOfPassword = md.digest(secretKey.getBytes("utf-8"));
byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);
SecretKey key = new SecretKeySpec(keyBytes, "DESede");

Cipher decipher = Cipher.getInstance("DESede");
decipher.init(Cipher.DECRYPT_MODE, key);

byte[] plainText = decipher.doFinal(message);

return new String(plainText, "UTF-8");
}
