is it safe to add SQL info in vb? - Blackbone - 08-05-2013
well, im making a login system using SQL, i've heard that you can decompile the vb application, so when they decompile they will get the source code? and get the sql info? :S :S :S

They will only be able to get the HostName and Connection Port.
The username and password isn't stored in the code.

Use a program like .Net Reflector (Paid Software) or ILSpy (Free Software).

I still wouldn't say it is safe. I would just have it interact with a PHP script server sided.

Actually, they'll gain access to your database hostname, your connection port, your database username, your database password, and with that, access to any database and table you have on that connection.

Ohh, forgot about those.
You can however make the user input the Database username & password along the the others.

I mean that's a good idea, but how many users do you want knowing the username and password of your database? Plus, if they needed to know that, they can just decompile and get the host and port to your database and log in regularly. Not much better solution.

Using a crypter to protect your program? It will certainly make it a bit more difficult, but anything can have symbols renamed, etc. and recompiled. It's just a matter of time.
