Questions about APP interface encryption

The company is developing an ios app interface to encrypt the APP interface. I am responsible for writing the website background. Currently, some interfaces implement functions that involve data modification, so we need to keep them confidential. Confidentiality: 1. IOS encrypted access, not encrypted parameters, encrypted access (access traces cannot be obtained illegally). I have never touched it and do not know how to implement it. 2. parameter encryption: before accessing the interface, obtain an encrypted string (A) on the WEB, and then encrypt the I APP interface.

Confidentiality:
1. encrypted access to IOS is not encrypted. the parameter is encrypted access (access traces cannot be obtained illegally). I have never touched it and do not know how to implement it.
2. parameter encryption: before accessing the interface, obtain an encrypted string (A) on the WEB, and decrypt the string (B) on IOS. the parameter (B) is included in the interface ), WEB access database verification (B ).

I think of so much. what is the mainstream authentication? is there a way to avoid using a database. Share: More
