- (id)responseObjectForResponse:(NSURLResponse *)response
                           data:(NSData *)data
                          error:(NSError *__autoreleasing *)error

    return [super responseObjectForResponse:response data:dataFromBase64 error:error];
}

@end


usage:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
      
manager.responseSerializer = [RNCryptResponseSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

[manager GET:@"http://127.0.0.1/base64.php"
  parameters:nil
     success:^(AFHTTPRequestOperation *operation, id responseObject) {
                NSLog(@"JSON: %@", responseObject);
              }
     failure:^(AFHTTPRequestOperation *operation, NSError *error) {
                 NSLog(@"XXXXXXXError: %@", error);
              }
];

it is just a demo which is about how to decrypt http message body by using afnetworking framework . This is just base64 decode...
