Read Credentials from Secure Store Service Programatically in SharePoint 2010

Hello,

If you want to read the credentials set in secure store service programatically, then the below code is helpful.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SharePoint;
using System.Runtime.InteropServices;
using System.Security;
using Microsoft.BusinessData.Infrastructure.SecureStore;
using Microsoft.Office.SecureStoreService.Server;


namespace ReadSecureStoreCredentials
{
    public static class SecureStoreUtils
    {
        public static Dictionary<string, string> GetCredentials(string applicationID)
        {
            var credentialMap = new Dictionary<string, string>();
            SPSecurity.RunWithElevatedPrivileges(delegate()
            {
                SPSite site = SPContext.Current.Site;
                SPServiceContext serviceContext = SPServiceContext.GetContext(site);
                var secureStoreProvider = new SecureStoreProvider { Context = serviceContext };
                using (var credentials = secureStoreProvider.GetCredentials(applicationID))
                {
                    var fields = secureStoreProvider.GetTargetApplicationFields(applicationID);
                    for (var i = 0; i < fields.Count; i++)
                    {
                        var field = fields[i];
                        var credential = credentials[i];
                        var decryptedCredential = ToClrString(credential.Credential);

                        credentialMap.Add(field.Name, decryptedCredential);
                    }
                }
            });
            return credentialMap;
        }

        public static string ToClrString(this SecureString secureString)
        {
            var ptr = Marshal.SecureStringToBSTR(secureString);

            try
            {
                return Marshal.PtrToStringBSTR(ptr);
            }
            finally
            {
                Marshal.FreeBSTR(ptr);
            }
        }
    }
}

Make sure you have added the following dll's

1. Microsoft.Office.SecureStoreService.dll located at C:\Windows\assembly\GAC_MSIL\Microsoft.Office.SecureStoreService\14.0.0.0__71e9bce111e9429c\Microsoft.Office.SecureStoreService.dll and

2. Microsoft.BusinessData.dll located at C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI\Microsoft.BusinessData.dll

And here is how you make use of the above code to read credentials from secure store service

Dictionary<string, string> SSCredentials = SecureStoreUtils.GetCredentials("SecureStoreId");
string strDU = SSCredentials.ElementAt(0).Value;
int SlashPos = strDU.IndexOf('\\');
this.strDomainName = strDU.Substring(0, SlashPos);
this.strUserName = strDU.Substring(SlashPos + 1, strDU.Length - this.strDomainName.Length - 1);
this.strPassword = SSCredentials.ElementAt(1).Value;

Bye for now :)
