Description

This cmdlet adds a secret value by name to a vault. When no vault name is specified, the secret is added to the default vault. If a secret with that name exists, it's overwritten. Additional data can be included with the secret if supported by the extension vault.

The default parameter set takes a SecureString object. If you run the command without specifying the secret value, the cmdlet prompts you to enter a SecureString. The text of the string isn't visible in the console.

Examples

Example 1

Set-Secret -Name Secret1 -Secret "SecretValue"
Get-Secret -Name Secret1

System.Security.SecureString

This example adds a secret named Secret1 with a plain text value of SecretValue. Since no vault name was specified, the secret is added to the current user's default vault. Get-Secret shows the secret was added.

Example 2

PS C:\> Set-Secret -Name Secret2 -Vault LocalStore

cmdlet Set-Secret at command pipeline position 1
Supply values for the following parameters:
SecureStringSecret: ***********

PS C:\> Get-Secret -Name Secret2
System.Security.SecureString

This example adds a secret named Secret2 to the LocalStore vault. Since no secret value was provided, the cmdlet prompts for a SecureString value. The console hides the string value as it is typed. Get-Secret shows the secret was added.

Example 3

$Metadata = @{ Expiration = ([datetime]::new(2022, 5, 1)) }
Set-Secret -Name TargetSecret -Secret $targetToken -Vault LocalStore -Metadata $Metadata
Get-SecretInfo -Name TargetSecret | Select-Object Name,Metadata

Name         Metadata
----         --------
TargetSecret {[Expiration, 5/1/2022 12:00:00 AM]}

This example adds a secret named TargetSecret to the LocalStore vault with metadata indicating the secret's expiration date. Get-SecretInfo retrieves the metadata for the newly created secret.

Example 4

$Metadata = @{ Expiration = ([datetime]::new(2022, 5, 1)) }
Set-Secret -Name PublishSecret -Secret $targetToken -Vault LocalStore2 -Metadata $Metadata

Set-Secret: Can't store secret PublishSecret. Vault LocalStore2 doesn't support secret metadata.

This example adds a secret named PublishSecret to the LocalStore2 vault with extra metadata. However, vault LocalStore2 doesn't support secret metadata and the operation returns an error.

Parameters

-Confirm

Prompts you for confirmation before running the cmdlet.

Parameter sets

(All)

Position:	Named
Mandatory:	False
Value from pipeline:	False
Value from pipeline by property name:	False
Value from remaining arguments:	False

-Metadata

Specifies a Hashtable containing key-value pairs to associate with the secret in the vault. The specified extension vault might not support secret metadata. If the vault doesn't support metadata, the operation fails and returns an error. The values of any metadata in the hashtable must be one of the following types:

• string
• int
• DateTime

Metadata isn't stored securely in a vault. Metadata shouldn't contain sensitive information.

Parameter properties

Type:	Hashtable
Default value:	None

Notes

When you run Set-Secret with the Name parameter to specify the name of the secret, the cmdlet calls GetSecret() that's implemented by the vault extension. Set-Secret passes through the name as provided by the user. The vault extension looks up the secret by that name. If GetSecret() returns a match, Set-Secret overwrites the secret unless you use the NoClobber parameter. The vault extension always writes the secret information it receives.

It's up to the vault extension implementation to decide whether or not to use a case-sensitive comparison on the name. For example, secret names in the Microsoft.PowerShell.SecretStore extension vault are case-insensitive. If the name you pass to Set-Secret differs only by case with the name of an existing secret in a SecretStore vault, the name is overwritten with the new value you provided.
