C# wrapper around CredWrite / CredRead functions to store and retrieve from Windows Credential Store. Windows OS comes equipped with a very secure robust Credential Manager from Windows Xp onwards, and good set of APIs to interact with it. However .Net framework did not provide any standard way to interact with this vault until Windows 8.1.
Microsoft Peer Channel blog (WCF team) has written a blog post in 2005 which provided basic structure of using the WIn32 APIs for credential management in .Net.
I used their code, and improved up on it to add
PromptForCredentials function to display a dialog to get the credentials from user.
Need: Many web services and REST Urls use basic authentication. .Net does not have a way to generate basic auth text (username:password encoded in Base64) for the current logged in user, with their credentials.
ICredential.GetCredential (uri, "Basic") does not provide a way to get current user security context either as it will expose the current password in plain text. So only way to retrieve Basic auth text is to prompt the user for the credentials and storing it, or assume some stored credentials in Windows store, and retrieving it.
This project provides access to all three
1. Prompt user for Credentials
var cred = CredentialManager.PromptForCredentials ("Some Webservice", ref save, "Please provide credentials", "Credentials for service");
2. Save Credentials
var cred = new NetworkCredential ("TestUser", "Pwd"); CredentialManager.SaveCredentials ("TestSystem", cred);
3. Retrieve saved Credentials
var cred = CredentialManager.GetCredentials ("TestSystem");
