I need to store passwords provided by the user. Yes, passwords. I could not use Hashes because I need to supply the password to another external service for authentication, and therefore I need to have the password.
What is the best and most secure way to store the passwords? As the external data provides private data it is of course very important that the password in my MS SQL DB is stored as safe as possible.
I'm trying to find out how i store user names and passwords in the web.config file. I have tried looking for documentation on this but haven't found any so far.
I see in the class library it says that the Authenticate method of the FormsAuthentication class is for use in authenticating credentials against those stored in the config file, but i don't know how to store them there to begin with. I want to store two username:password pairs in the web.config file preferably encrypted.
one of these username:password pairs i want to be hard coded. The other i want to be able to be reset with a password reset form which I will code later. I guess there maybe a method for creating a sername:password entry in the web.config which could be used with my password reset form if such a method exists. But I need to know how to hand code the username:password entries into the web.config file to begin with and to beable to create the hard coded pair.
code I need to add to my web.config file i need to add and in what section?
also can you point me in the direction of a method used for creating username:password entries in web.config
My issue today is that i have a MySQL Database and am using the security framework provided by the ASP.NET Membership and Role Providers...I override the default methods with my own MySQL.
Now the issue comes in when i someone would like to have their password reset. My application is running entirely on an Intranet so i cannot have their passwords emailed to them. Is there a way i can have this information displayed in any way so that the user can use it to Log Reset, Create Accounts or Recover their lost passwords on an intranet without the administrators intervention?
Recently i had an approach as follows. In my web.config<system.net><mailSettings><smtp deliveryMethod="pickupDirectoryLocation" and my location was a folder on C drive as c:/SavedPasswords. Now i understand this was such a big security threat and thats why i am looking for a better option.
I would have that folder created using my System.IO and then the Mail is dropped into that folder. Then after the process is successful, i tell the user to check into that location and Read its content.
Then there is a global variable that is set to true...meaning that the folder at c:/ has been created. then there is a Method in a certain class that once it sees this variable True, it reads the readers c:/ and deletes that folder "save" if it exists;
I have a small database, with a very small number of users. The passwords were stored as clear as the database was so small and held no sensitive data. The database is now to be expanded and passwords are required to be encrypted. I can change the Password Format in the web.config, but is there a way to change the existing passwords from clear to encrypted?
View 1 RepliesUpgraded from SQL Server 2005 to 2008, now when my app tries to execute If Membership.GetUser() Is Nothing Then it says A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified). Confused as to whether this is a problem connecting to ASPNETDB.MDF or my DB in general so I went into Server Explorer and created a connection to my DB, tested successfully, then grabbed the connection string. It matches what's in my web.config so I think the problem is ASPNETDB.MDF only works with SQL Server 2005 Express. If this is true, what do I need to do to use this app with SQL 2008? Should I just delete ASPNETDB.MDF?

There are three ways of resetting and changing passwords explained at
Microsoft ASP.NET site[URL]
Step 1: Helping Users Recover Lost Passwords
Step 2: Changing Passwords
Step 3: Allowing Administrators to Change Users' Passwords
In step 1 and step 2 end user passwords are sent by an email.
In Step 3: functionality is explained where administror changing the password and sending through email msg. refer "I encourage those readers interested in this functionality to become more familiar with the code and try extending the functionality to include sending an email to the user whose password was changed.

I have an asp.net page where I have used FormsAuthentication.HashPasswordForStoringInConfigFile. Encrypted password is saved in database. I have created a forgotPassword page. Where I need to send user his password. How can I decrypt it and send it to user. if SHA1 can not be decryoted what other option should I use to encrypt the passwords?
View 5 RepliesI want the login password to not be sent in plaintext (due to the risk of hijacking). I know that this can be achieved in principle using MD5 or the like, but is there a common implementation for use with Asp.Net? Of course, it's crucial that the resulting hash (?) isn't easy to decrypt. When I read various posts on this matter, some people say it's just to do a reverse on the encrypted string, so that in effect, this is totally useless.

View 5 RepliesI'm looking to create my application as secure as possible. Now I have following line of code:
[Code]....
As you can see, my password is in plain-text in the code. Now, I presume it's easy to decompile a code using a tool and getting your hands on the password. Since these are my AD Admin-credentials this is not that good.The AuthenticationTypes are secure, I think. They encrypt the data before sending it to the network.So there's just the problem of the plain-text password. I've searched for it on Google but can't find the proper solution. I've found alot about encrypting passwords in the web.config.
I've created a website with users and passwords and such for authentication.When a user is created through the "administer website" function of asp.net 4.0 where are the passwords stored? Is there a way to manually change passwords in the database?
View 3 RepliesI setup a website to use hashed passwords with the membership provided by Asp.net. I'm looking for a way to convert all passwords to clear text. Hashed passwords are overkill for this site and many users can't figure out how to cut and paste the complex temporary password when they request a forgotten password. I understand that you can't retrieve a hashed password.
<membership defaultProvider="CustomizedProvider" userIsOnlineTimeWindow="15">

I have been killing myself over this for a couple weeks now and cannot find a viable solution. Here's my scenario:
I have a DTSX package that imports user data from an external database. It then creates user accounts and profiles in the local database. Users can also be created via a custom ASP.NET Membership Provider. The provider must be able to authenticate both types of users.
This was all fine and dandy during development because passwords were stored as clear text. However, now that we're ready for release the passwords format of the provider must be set to encrypted and so the users created via the DTSX must be created with an encrypted password. (I'd prefer the passwords were hashed but the client's requirements are that passwords be recoverable). The real problem seems to be creating an encrypted password within the DTSX that will be decryptable by the ASP.NET Membership Provider.
My original solution was to have the DTSX call a CLR stored procedure that had access to the same encryption logic as the provider. I got it working but our client wouldn't enable CLR integration. So that's out the window. Now I'm investigating alternatives. One alternative is to simply use the built-in encryption methods of T-SQL. But how do I share the keys used for the encryption/decryption?
My question is, is it possible to generate a password in T-SQL, say using EncryptByKey, that will also be decryptable by my provider? This means that the key in SQL must match the key in my machineKey configuration.
So I have an ASP.net application, with an ActiveX Control which brings up a pop up
When I point to the application directly through IP there is no problem with the pop up eg. xxx.xxx.xxx.xxx/MyApp (under Default Website in the IIS -- IIS 7) Problem arises when I set up the IIS to point it to a domain [URL] which points to the above IP (under another "Site" i.e. not the "Default Site in IIS 7)
I then get this weird
Microsoft .net Security Warning Never enter personal information or passwords into a window unless you can verify and trust the source of the request.
Source: [URL]
The site is in the trusted list -- just like when I was using the IP only . Is there any setting in the IIS I need to tweak for IE to trust me fully.
I use password recovery control for testing purposes. Passwords are stored in the database as hashed format.
Control can successfully send email to user but password always wrong. whats wrong here?

Before I continue I'm going to let everybody know that I am not trying to follow a traditional .Net Membership Provider. I'm attemping to write my own Membership Provider which does not extend the default .Net Membership Provider b/c I feel that in areas it can become extremely cumbersome. Please keep this in mind before responding. Also keep in mind that I am trying to learn from this experience, not find an easy solution for some client's application.I am writing a custom membership provider that has password formatting functionality similar to .Net's default membership provider. I'm looking for soe good/easy examples of ways to encrypt/decrypt or hash password values. I previously tried going the RSA route, but got stuck when I had to Import an RSAParameter and was unsure of how to generate a RSAParameter.
I would like to have both Hashing and Encryption available, but only need Encryption. I'm also looking for a very strong encryption. I'm storing the password format in an external .xml file (similar to how the web.config stores the password format for .Net's Membership Provider) which will become manageable from the administrative side of my webapplication.If anybody knows of any existing Encryption libraries that may provide assistance, please feel free to post links. I only ask that they be open source solutions so I can see how they went about doing this.
I have a website running on iis 5.1 with asp.net 2.0. Where in the windows registry can I change the requirtements for some the security features? For example, I do not want to enforce strong passwords and I do not want to use the secret question and answer features.
View 4 RepliesI have a project that I developed in VS2005 and that has been put into VSS. I am trying to "get" it on a new machine and convert it to VS2008 because that is what is installed on the new machine. I am having problems with it that I think originate in its working folder. So my basic question is, when you try to work with a solution that's in VSS should you maintain the same folder structure that it had when it was originally checked in? I'm not particularly happy with its original structure because it goes on and on seven levels deep, and I wanted to just cut it down to C:ProjectsResNew, but if that's what it takes to get it to work, I'll do it.
