In general, the current SaaS service provides the current SDK or API docking service that involves an authentication and data encryption issue. It is generally common practice to configure the use of asymmetric encryption to solve this problem, you

Encryption and authentication First, we need to distinguish the two basic concepts of encryption and authentication.Encryption encrypts data so that illegal users cannot obtain the correct data even if they have obtained the encrypted data.
