The following implementation code adds a category for NSData and NSString, respectively. Can be called directly when used.It should be noted that AES is not a hash algorithm, encrypted and decrypted results, and not necessarily the same as the original, please pay a

One of the issues that we often need to consider when PHP is requesting an interface is the security of the data, which is likely to be intercepted using fillder such as a grab tool. A better solution is to encrypt the data to be requested before the client request is initiated. The server API receives the request data, then decrypts the data, returns the result to the client and encrypts the data to be returned, and the client receives the data when it is returned to decrypt. Therefore, the sec
