//例如

cipher.init(Cipher.ENCRYPT_MODE,convertSecretKey);
byte[]?result="哈哈哈".getBytes();
for(int?i=0;i<5;i++){
????result=cipher.doFinal(result);
????System.out.println(HexBin.encode(result));
}

//解密
cipher.init(Cipher.DECRYPT_MODE,convertSecretKey);
for(int?i=0;i<5;i++){
????result=cipher.doFinal(result);
????System.out.println(new?String(result));
}
//最后能解密成功得到最開始的值
