用法：

com.str.Encrypt("2017-05")//結果：68f4a7903a9fe6085d2301ac68cc039ccom.str.Decrypt("68f4a7903a9fe6085d2301ac68cc039c")//結果：2017-05

//加密string str1 = Encrypt.EncryptByAES("2017-05", "12345678900000001234567890000000");//解密string str2 = Encrypt.DecryptByAES("68f4a7903a9fe6085d2301ac68cc039c", "12345678900000001234567890000000");
