Good day everyone! I've been using AFNetworking 2.0 for a quite a while and because input was always of https with json - never had any problem. Yet now we have a custom written on C server which works only with HTTP and sends encrypted raw byte data.
As far as I understand it's necessary to use some sort of serializer , but i can choose only from: AFHTTPResponseSerializer/AFJSONResponseSerializer/AFXMLParserResponseSerializer/AFXMLDocumentResponseSerializer/AFPropertyListResponseSerializer and none of them seems to fit. What's the best solution? As result i need decrypted NSData which i can parse byte by byte.
All the possibilities of encryption rule out a standard ResponseSerializer. Some of the encryption properties include algorithm, key, key size, mode, possible iv and padding.
The solution is to decrypt the received data in a separate step.
In order to decrypt the data you need to know the algorithm, it's parameters and the encryption key. It is also possible that additional encryption information is added to the encrypted data such as an iv, KDF reputation count, etc. You need to obtain this information from the server developers.
