In the paper we expound some key techniques for the development of an electronic seal system,including system architecture,middleware,HASH algorithm,electronic seal integrity strategy,remote user login technology,electronic document integrity strategy,and digital signature etc.

This paper analyses the advantages and disadvantages of the two cipher algorithms-DES algorithm which is representative of traditional cipher system and RSA which is representative of public key cipher system, brings forward a mode of data encryption-the mix encryption of DES、RSA and HASH combining HASH algorithm to guarantee the security of network data.
