Singature

Signature is the only criterion for determining data authenticity between you and LianLian. We support RSA digital signature with MD5withRSA algorithm in key size 1024, 2028 or 4096 to implement the signature process.

RSA Data Security Digital Signature Process

This process is from Microsoft documents, RSA Data Security Digital Signature Process

There are two sets of public and private keys, one from merchant and another one is from LianLian in the whole verification process:

• When you submit request to our server, you need to build the signature source and encrypt it with your private key to generate signature. After receiving your requests, we decrypt the signature with your public key and then check the authenticity.

• When you receive notifications from our server, you need to obtain the signature and parameters in our requests first, and then verify them with the public key provided by us.
