Internals of IEPasswordDecryptor

Like most browsers, Internet Explorer also has the single sign-on feature which stores the username/password for already authenticated websites. Whenever user login to any website, IE prompts the user for consent to store the password for future use. If user acknowledges then username/password along with website link will be stored in IE secret store. So the next time onwards whenever user visits the same website, IE automatically populates the username/password field from its store thus preventing user from entering credentials every time.

Internet Explorer stores two type of passwords, Autocomplete and HTTP basic authentication based passwords. Autocomplete passwords are normal website login passwords such as email, forum websites. HTTP basic authentication password is the one which is required to login to website itself. As soon as user tries to access the website, IE prompts with login dialog box asking for username/password. Generally proxy servers and router/modem configuration websites uses these kind of authentication mechanism.
 
Internet Explorer below version 7 stores both Autocomplete and HTTP basic authentication passwords in the secure location known as 'Protected Storage'. Windows has introduced 'Protected Storage' to allow applications such as IE, Outlook to store the secrets securely in an encrypted format. Below is the registry location corresponding to the 'Protected Storage'.

HKEY_CURRENT_USER\Software\Microsoft\Protected Storage System Provider

With version 7 onwards IE has changed the location of password store to provide better security mechanism compared to existing 'Protected Storage'. Now IE stores all the Autocomplete passwords in below mentioned registry location in an encrypted format.

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms\Storage2

Here is the screenshot of typical entries stored at this location


Here each entry corresponds to a hash of the website for which username/password has been stored. So one must know the website login link to recover the password. In order to solve this problem, IEPasswordDecryptor uses the website list from the IE history and verifies if any of them matches with stored hash entry. So if a website link is not present in the IE history then the password for such stored website entry cannot be recovered. In such case you can use 'Add Website' option of IEPasswordDecryptor to add the website link to existing IE history as shown in the Screenshot 3 below.

The HTTP basic authentication passwords are stored in the 'Credentials store'. The 'Credentials Store' is newly introduced secret store mechanism by Windows and it is generally used to store the network login passwords. Its location is given below.

[Windows XP]
C:\Documents and Settings\[username]\Application Data\Microsoft\Credentials

[Windows Vista\Windows 7]
C:\Users\[username]\AppData\Roaming\Microsoft\Credentials
 
IEPasswordDecryptor automatically detects the IE version and correspondingly decrypt the username/passwords from the appropriate secret store.
