You can't protect a .NET DLL from decompilation. Period.
answer to both: you keep the interesting parts on a server you control, and make people interface with it through some sort of API. Assume that anything you send to a user's computer will be decompiled and hacked within hours of releasing it.
What are you making?
How to use firebase more secure....?
can email pass and extra security in it protect firebase completely..?
What are you exactly trying to protect?
If you need this much security, just communicate via an API
exe and ddl files
for?
c# simple project
I really don't see the point in going to such an extent for protection
actualyy i have dll whose name is activator
when i check exe from extreme dumper
than activator dll comes
and all private information is shown...
for this i think i have to use rest api
i am right...?
You'd have to use API for the functions of the app, just not only the authorization
So basically, replace your entire app with APIs
ok
activator dll?
what's that?
this is my exe file
and on this my firebase private fill and information of soft
Oh you mean the authorization library?
yes
privatek key and other information
Interesting project that needs this much security 👀
i am not a programmer ,,,
and have not very much knowledge..

Pretty much, although I wouldn't recommend self-hosting the service.
As you'd have to be the person that maintains it.

That way client never has the back-end, it's just an app that displays things based on the responses.

If you want your API to be up, yes.
But it's not your PC that has to be online. It's the services.

Only the host of said API has to be turned on and is connected to the internet.

what nuget packages to include in c# program
$obfuscation
"Then finally, there is that question of code privacy. This is a lost cause. There is no transformation that will keep a determined hacker from understanding your program. This turns out to be true for all programs in all languages, it is just more obviously true with JavaScript because it is delivered in source form. The privacy benefit provided by obfuscation is an illusion. If you don’t want people to see your programs, unplug your server."

* Spend your effort on putting proprietary things in your api, and keeping the distributed code as empty as possible
* Use AuthN/AuthZ to control who/what/when/etc...
* Free obfuscation is worth the amount your paid for it -- it's already broken and most decompilers out there can make sense of it.
* Paid ofbuscation will bankrupt you unless you have a very strong revenue stream and can justify the additional cost with gained sales
* The "threat" of someone hijacking your UI and shimming it to make it provide them money is not a real threat. If this is legitimate software, you can ruin their business with lawsuits

Is it important to obfuscate C++ application code?
In the Java world, sometimes it seems to be a problem, but what about C++? Are there different solutions?

If the core exists on the API, it's impossible.
You don't do the work on the client, always do it on the server.

As said, not only the authorization happens server-side
You can use OAuth (or others) which then allows you to work with the API based on the OAuth key.

don't ask the user's computer for the date then
because they can change the system clock whenever they want
Also, if the authorization happens server-side, just use HTTPs.
If the date is not matching, HTTPs connection will fail.
is vps is essential
or simple hosting also work
not sure what you mean by simple hosting
you could host your service on any computer but it's best to do it on something reliable, which a PC running in your basement isn't compared to cloud hosting
depends what your use case is
sir my requirement is -- all firebase private key and important code is safe and block unblock and also some function of app is on server...
i need .net hosting... or vps
my clients are nearly 400
and data is text only...
if you have 400 clients you should probably use reliable hosting
so a VPS or other cloud server
potentially multiple with failover
if i only use authorisation than asp.net hosting work...?
Is there is any method so i can send free sms to customer...
hosting asp.net on what?
and none that i know of
API PRIVATE KEY AND OTHER IMPORTANT INFORMATION OF MY APP
idk what the caps are for
BY MISTAKER
by mistake
"asp.net hosting" isn't hosting, that's just the framework your service is built on
you still need a server somewhere to run it
whats is IIS SERVER
I heard many times...can i use IIS SERVER INSTEAD OF OTHER CLOUD OR VPS
again, IIS is a service that runs on a server
you need an actual computer to run code on, whether it's in your house, bare metal in a datacenter, a VPS, something "serverless" (spoiler: there's still a server), etc.
it seems like you're looking for an easy free option, the answer is that for 400 clients there isn't one
i assume they're paying you, so you should use some of that revenue to support your infrastructure

can this really works
It's fake
clickbait
There are no free sms services
I recommend you to stop looking for one.
And simply just pay the price especially if you got 400 clients as you said.

thanks for best guidance...
and last thing i search for server which is best and secure...
in ur view...?
"secure" ??
Best, it's probably AWS or Azure. But they're also expensive.
Cheapest, it's probably OVH (If it's VPS, not counting web server)
