=======
|
|
|
|
The PSCredentialStore is a simple credential manager for `PSCredential` objects. It stores PSCredentials in a simple json
|
|
file. You can choose between a private and shared credential store. The private one exists in your profile and can
|
|
ony accessed by your account on the same machine. The shared store enables you to use different credentials for your
|
|
scripts without exposing them as plain text.
|
|
|
|
PSCredentialStore was developed to simplify the delegation of complex powershell scripts. In this case you often
|
|
need to store credentials for non interactive usage like in scheduled tasks.
|
|
|
|
Starting with version `1.0.0` PSCredential uses Pfx certificates fo encryption. You can use Pfx certificate files
|
|
or certificates stored in the certificate store.
|
|
|
|
For more details read the [about_PSCredentialStore](/docs/about_PSCredentialStore.md) page on github or via CLI with
|
|
`Get-Help about_PSCredentialStore`.

|
|
============
|
|
|
|
- PowerShell >= `5.1`
|
|
- .NET Framework >= `4.6` or .NET Core >= `1.0`
|

|
:bomb: About Security
|
|
============
|
|
|
|
>This section explains some security topics and the the design decisions we made to balance the usage and security needs.
|
|
|
|
To be able to delegate `PSCredentials` objects we can't exclusively rely on the `SecureString` cmdlets. You can't
|
|
decrypt and reuse such credentials from a different user account or even machine. This is caused by automatically
|
|
generated encryption key which, is used create a `Secure String` based encrypted string.
|
|
|
|
In order to delegate a password, while still using the underlying security framework, we have to provide a custom
|
|
encryption key. This leads to the fact, that everyone who has access to the key could encrypt or decrypt your data.
|
|
|
|
So we decided to use the public and private keys from valid certificates as part of the custom encryption keys to encrypt your data.
|
|
|
|
This means clearly: Everyone who has access to the `CredentialStore` needs also access to the certificate file to work with it.
|
|
|
|
Keep in mind you need to secure the access with your NTFS file permissions to avoid unwanted usage. Another option is
|
|
to import the certificate into your certification vaults of you operating system. In this case you can grand the
|
|
permission to the certificates itself.
|
|
|
|
Here is s brief hierarchy description of the certificate location: *(First match wins)*
|
|
|
|
| CredentialStore Type | Certificate Location |
|
|
| -------------------- | ---------------------- |
|
|
| Private | `CurrentUser`\\`My` |
|
|
| Shared (Windows) | `CurrentUser`\\`My` |
|
|
| | `LocalMachine`\\`Root` |
|
|
| Shared (Linux) | `LocalMachine`\\`My` |

|
|
============
|
|
|
|
:artificial_satellite: PowerShellGallery.com (Recommended Way)
|
|
---------------------------------------
|
|
|
|
* Make sure you use PowerShell 5.1 or higher with `$PSVersionTable`.
|
|
* Use the builtin PackageManagement and install with: `Import-Module PowerShellGet; Install-Module 'PSCredentialStore' -Repository 'PSGallery'`
|
|
* Additionally use the `-AllowPrerelease` switch until we publish the final release!
|
|
* Done. Start exploring the Module with `Import-Module PSCredentialStore ; Get-Command -Module PSCredentialStore`
|
|
|
|
:building_construction: Manual Way
|
|
----------
|
|
|
|
* Take a look at the [Latest Release](https://github.com/OCram85/PSCredentialStore/releases/latest) page.
|
|
* Download the `PSCredentialStore.zip`.
|
|
* Unpack the zip file and put it in your Powershell module path.
|
|
* Don't forget to change the NTFS permission flag in the context menu.
|
|
* Start with `Import-Module PSCredentialStore`
|
|
|
|
:sparkles: Quick Start
|
|
-----------
|
|
|
|
**1.** First we need a blank credential store. You can decide between a *private* or *shared* store. The private
|
|
Credential Store can only be accessed with your profile on the machine you created it.
|
|
|
|
Starting with version `1.0.0` you can decide the storage type of your fresh created certificate. As default
|
|
PSCredentialStore creates a new pfx certificate file beside the credential store itself. Optionally you can provide
|
|
the parameter `-UseCertStore`. This imports the new certificate in the user or machine certificate store as well.
|
|
|
|
```powershell
|
|
# Private credential store
|
|
New-CredentialStore
|
|
|
|
# Private credential store with certificate store usage
|
|
New-CredentialStore -UseCertStore
|
|
|
|
# Shared credential store
|
|
New-CredentialStore -Shared
|
|
|
|
#Shared credential store in custom location
|
|
New-CredentialStore -Shared -Path 'C:\CredentialStore.json'
|
|
```
|
|
|
|
**2.** Now you can manage your credential store items:
|
|
```powershell
|
|
# This will prompt for credentials and stores it in a private store
|
|
New-CredentialStoreItem -RemoteHost 'dc01.myside.local' -Identifier 'AD'
|
|
|
|
# You can now use it in other scripts like this:
|
|
$DCCreds = Get-CredentialStoreItem -RemoteHost 'dc01.myside.local' -Identifier 'AD'
|
|
Invoke-Command -ComputerName 'dc01.myside.local' -Credential $DCCreds -ScripBlock {Get-Process}
|
|
```
|
|
|
|
The credential store contains also a simple function to establish a connection with several systems or protocols.
|
|
If you have already installed the underlying framework / modules, you can connect these endpoints:
|
|
|
|
* **CiscoUcs** - Establish a connection to a Cisco UCS fabric interconnect.
|
|
* Required Modules: [`Cisco.UCS.Core`, `Cisco.UCSManager`](https://software.cisco.com/download/release.html?i=!y&mdfid=286305108&softwareid=284574017&release=2.1.1)
|
|
* **FTP** - Establish a connection to a FTP host.
|
|

|
|
* **ExchangeHTTP** - Establish a remote connection with an Exchange endpoint via http.
|
|
* Requires PowerShell remoting
|
|
* **ExchangeHTTPS** - Establish a remote connection with an Exchange endpoint via https.
|
|
* Requires PowerShell remoting
|
|
* **SCP** - Establish a SCP connection.
|
|
* Required Modules: [`WinSCP`](https://www.powershellgallery.com/packages/WinSCP)
|
