NetworkPasswordDecryptor is the free tool to instantly recover network
passwords stored in the 'Credential Store' of Windows. Windows
'Credential Store' provides the framework for storing various
network authentication based passwords in secure encrypted format.
Not only Windows uses it to store network authentication passwords,
but also other applications such as Outlook, Windows Live Messenger,
Remote Destktop, Gmail Notifier etc uses it for
storing their login passwords. These network passwords are saved only when
the user has selected 'Remember Password' option during login time. |
|
|
|
These network passwords are stored in encrypted format and even
administrator cannot view these passwords. Also some type of
passwords cannot be decrypted even by administrators as they require
special privileges. In this context, NetworkPasswordDecryptor makes
it easy to enumerate and decrypt all the stored network passwords
from Credential Store.
NetworkPasswordDecryptor is a
standalone portable tool and works on wider range of platforms
starting from Windows XP to latest operating
system, Windows 7. |
| |
| |
|
NetworkPasswordDecryptor can recover following
passwords on all versions of Windows starting from XP to Windows 7.
|
- All network authentication passwords stored by Windows.
- Basic/Digest authentication passwords stored by Internet
Explorer
- Google login password stored by GMail Notifier
- Remote Desktop stored passwords.
- Exchange server login passwords stored by Outlook.
- Login passwords of Windows Live Messenger
|
NetworkPasswordDecryptor also allows you to delete any of the stored
passwords from 'Credential Store'. This is useful if the password has
changed or if the user has accidently saved the critical password.
Also it provides option to save the decrypted network password list to
TEXT or HTML format. |
| |
| |
|
Windows 'Credential Store' support
following different type of network secrets.
|
- Domain Password
- Generic Password
- Domain Visible Password / .NET Passport
- Certificates
|
Each of these types have different level of access and follow
different encryption mechanism. For example 'Generic Passwords' can be
decrypted by corresponding users directly. However decryption of domain
passwords require special privilege and can be decrypted only in the
context of system process, LSASS.exe.
This makes it easy for application to choose suitable type of encryption
mechanism for storing their login passwords.
Windows allows application to manage these network passwords using
Credential
Management API functions to store
and retrieve the passwords. Except passwords of
Domain type all other passwords can be retrieved using such functions.
Decrypting domain type passwords require special technique of executing
entire decryption operation in the core of LSASS process using
undocumented functions.

passwords read the following research article,
