一看就是十六进制

十六进制也是二进制的一种。

这个肯定是个的字符串,你从哪里截取下来的 ,你可以推断一下是哪个文件转换成的字符串

少打了几个字 16进制的,比如将某个文件的流,图片的流通过base64转换成字符串

以0x开始的数据表示16进制，计算机中每位的权为16，即(16进制)10 = (10进制)1×16
16进制与10进制的对应关系是:0-9对应0-9;A-F对应10-15;N进制的数可以用0~(N-1)的数表示，超过9的用字母A-F。

java如下

public static String File2StringByBase64(String fileName) throws IOException
{
    int len = 0;
    FileInputStream inputStream = new FileInputStream(fileName);

    int length = inputStream.available();

    LogUtil.log(TAG, "[" + TAG + "] File2StringByBase64  " + fileName);
    LogUtil.log(TAG, "[" + TAG + "] File2StringByBase64  " + length);

    byte [] byteArray = new byte[length];

    inputStream.read(byteArray);

    String bitmapStr = Base64.encodeToString(byteArray, 0,
            byteArray.length, Base64.DEFAULT);
    return bitmapStr;

}

十六进制，一般以0x开始的数据表示16进制！

二进制数据的HEX编码很少会加上“0x”前缀，怀疑这是一个超大数的十六进制表示。

这是16进制加密后的数据。

有可能使加密后的图片的16进制吧

ox开头 应该是16进制
