Use For Login Passwords On The Programs?
Mar 16, 2009
Yesterday night a friend did ask me what encrypting i normally use for my login passwords on the programs i make.Wel my answer = NO Encryption cause most of programs i write with a login on it as protection is only for local use.But still lately iam starting to get more intrested to make programs that are using external databases like MySql.So my Question is how to put sh1 encryption on a password.i need this in 2 ways 1. how to use it when i register a password to a database.2. how to use it when i read the password out of the database.( i dont need to know how to make a connection to mysql or etc. just the info to encrypt.)

I want to create a login system that reads the usernames and passwords for a list of arrays:[code]I have managed to code the program so it accepts the correct username and password and sends a error message when they don't match. The problem I'm having is when the user enters a username that isn't on my Username list. The program always crashes when I enter say "admin1000".[code]

I am sure this can be done, as Visual Studio is basically built this way. What I want to do is simply make a class that my other workmates can use. But rather than have it in a code form, I want to build it (partially), and then my workmate can add it into their programs (sort of, like the add reference for the .NET stuff).

Well, the website loads, but when you go to the login page (Forex Trading Social Network | Online Forex Trading Forum and Social Networking Site) and try to log in, it doesn't work.

When you've finished a program and you're trying to distribute it to the mass public. How is the best way to go about doing this? What sites would you post your program on and getting the word out that there is a new program on the block and it does xyz. This is directed to freeware so there wouldn't be any advertising.
Sorry for not explaining it very well the first time.

I'm trying to write a program right now for my computer science class for a program where you insert text into a text box, (the text being a password), and then click a submit button. The goal of the assignment is to have a program that looks at the user given password and see if it matches the const password (or one of the three const passwords in my case). If it doesn't, it is supposed to loop back so you can re-input the password. Also, If you enter the correct password, the loop ends and you are to get a msgbox (or, in my case three different ones), and then the application closes. We are to write the code so that if the password is wrong "x" (insert 3 as the number I have chosen), a MsgBox will pop up with a message saying
something along the lines of "you have gotten the password wrong to many times.", and then the application is supposed to close. I don't think I could rant on much more, I've done a good (or in my eyes terrible) job of summarizing the assignment.
[Code]...
My problem (aside from, I don't know, a problem with my code itself) is that when It reaches the loop, it goes through all the code again, but I'm unable to change the user given password, and so it just pops up the three failed password entry MsgBoxes (the code for which is temporarily removed), then the failed to many times MsgBox, OR one of the successful message boxes. What I'm wondering is if anyone can help me fix my code so that it functions as desired.

I am using VB.NET 2010. I have a Windows 2008 Web Server, where about 80 user accounts are activated. It is NO Active Directory Environment!!! This is a server, where Windows SharePoint Services are hosted. So, once a year, I have to give all users a new password. (I have to give it, because of some security thinkings of the owner of this Page). So, changing the password for each person is a very long activity. How can I do this by a VB.NET Program? - When I am logged on as an Administrator to this server?

The following webpage talks about using impersonation in code (ASP.NET)[url]... I am thinking about creating a class for the code, then the application can call impersonateValidUser and undoimpersonation.
I am concerned about putting usernames and passwords in my code as surely anyone will be able to see them using a tool like ILDASM. What is the best way to hide these passwords?
The article has a section titled: Impersonate the IIS Authenticated Account or User. I thought about creating an impersonated user in the Web.Config, but this would mean that the entire application is run as the inpersonated user. I only want a very small part of the application to run as the impersonated user - when it is necesary to access and update active directory.

I recently made a small app for a friend and then made it a public app, in doing so I forgot that it connects to my MS SQL DB and checks for values. Someone used Red Gate .Net Reflector to get my password and destroy it all. I've contacted their ISP and they are looking into it, apparently this person has a static ip with them.So this is a lesson learned at a heavy price for me. How can I prevent this from happening again? How can I get away from the unsafe connection string they were able to use?

Can someone tell me how Active Directory stores it's passwords for users? Is it like this answer : storing passwords in SQL Server Is it a hash and a salt or multiple hashes?
EDIT I ask because I want to mimic the way they store them for a custom authorization application I want to build. Or if someone can offer a existing framework or class that handles user authorization for a web application. If I can use asp.net membership for multiple applications using web service that would be even better.

I have a scenario that has been troubling me for years. If you have to connect to a database or other service (like a web service) using a username and password, where would be the safest place to store this information if you are connecting through a .NET assembly? I understand that you would have to encrypt the password, but then you run into a kind of chicken-egg problem -- fine -- you can encrypt it, but then where do you put the key?In .NET, you can't hardcode the password because you can decompile .NET code.
I looked at using assembly based rights with Isolated Storage, but MS recommends against storing unencrypted secret items there because priveledged users can gain access, so again, we are moving the problem from point A to point B. So for examplem, a domain admin with no need to know about the information in a database would be able to get access because of the ability to be an admin on any workstation on the domain.You can encrypt App.Config and Web.Config, but I believe priveledges users can access the keys. I think you run into the same problem with DPAPI.
I had considered storing the passwords, encrypted in a remoted database and getting them through OS authentication, but our department prohibits the storage of passwords on database servers. I am pretty sure I am stuck and wanted confirmation.

What's the simplest way to upgrade a VB.NET site to using encrypted passwords? Are there easy to use encryption algorithms built in to System.UI?My site is using plain text password storage, and it will soon be going to a public server at godaddy from a private one on the local network. I'm going to have to start adding in encryption algorithms to all the password parsing functions, and it would be nice if I could just set a SALT key in the web.config file and Encrypt(password) or something like that.

I need to write a program allowing the user to enter up to five passwords at one time. I have the textboxes set the way I need. When the user presses the button, the code should check every password they ve entered, and flag any passwords that are invalid. A valid password includes the following:
At least 6 and not more than 15 characters
At least one uppercase alpha character
At least one lowercase alpha character
At least one numeric character
I'm a little confused about how to check each character of the entered passwords for these conditions.Because it must include alpha characters, I believe I have to do something with ASC and CHAR variables. This is my first post and I need to have this done within a few hours, haha. Help would be awesome.

I am using vb.net (visual studio 2010) and have made a form application that uses a login screen. All that works but I am having trouble any firm way to encrypt the passwords in the database. The encryption doesn't have to be very high standard as its just for a college project. Whats the best way to encrypt the password into the database? Or just encrypt the password string, I can then sort out the database end myself.

I want for the local intranet user with limited rights to be able to update Active Directory from his own limited account. For this, we created a separate Windows account as an intermediary, which has appropriate Domain Admin permissions. Now we want to use these credentials (account name, password) in the client program (a Windows Forms application) the user will work with to update Active Directory.
The problem is... it seems DirectoryEntry object in .NET 2.0 only accepts plain passwords. Hashed passwords (I tested MD5) don't work.
Is there a way to configure DirectoryEntry so that it would work with hashed ones? Something to do with authentication types?
Below is my sample code that works with plain passwords but rejects hashed:- - -
Dim Entry As DirectoryEntry = New DirectoryEntry(ActiveDirectoryServer, sUserName, sHashedPasswordUsingMD5)
Dim Searcher As New DirectorySearcher(Entry)
