Hi Xiaoyan,

I would suggest you read the format specifications about each TLV block 
inside the Data structure (http://named-data.net/doc/NDN-TLV/current/).

For example, here is the specification of the Signature format 
(http://named-data.net/doc/NDN-TLV/current/signature.html)

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.
