    <p>Hi Xiaoyan,</p>
    I would suggest you read the format specifications about each TLV
    block inside the Data structure (<a class="m_-4741045045389801808moz-txt-link-freetext" href="http://named-data.net/doc/NDN-TLV/current/" target="_blank">http://named-data.net/doc/<wbr>NDN-TLV/current/</a>).
    <br>
    <br>
    For example, here is the specification of the Signature format (<a class="m_-4741045045389801808moz-txt-link-freetext" href="http://named-data.net/doc/NDN-TLV/current/signature.html" target="_blank">http://named-data.net/doc/<wbr>NDN-TLV/current/signature.html</a><wbr>)<br>
    <br>
    According to the documentation, several types of signature are
    supported, such as SignatureSha256WithRsa. Using
    SignatureSha256WithRsa, a producer first calculates SHA256 hash of
    the Name, MetaInfo, Content and SignatureInfo, then the producer
    signs the SHA256 hash using an RSA private key.<br>
    <br>
