Implement Context integration for storing API keys

[MariusStorhaug]

Summary

Implement the Context module integration for PowerShellGallery to securely store and manage API keys for the PowerShell Gallery.

Background

The Context module (PSModule/Context) provides a secure, encrypted storage mechanism for module settings and user credentials. The GitHub module (PSModule/GitHub) serves as a reference implementation showing how to integrate Context.

Requirements

1. Connect-PowerShellGallery Function

Create a function that enables users to connect to the PowerShell Gallery by storing an API key context.

Behavior:

• When called, it should open the user's browser to the PowerShell Gallery API key management page: https://www.powershellgallery.com/account/apikeys
• Prompt the user to enter their API key (as SecureString)
• Store the context using the Context module with the vault name PSModule.PowerShellGallery
• Support storing multiple contexts (e.g., for different accounts/organizations)
• Return the created context object when -PassThru is specified

Parameters:

• -Name - A friendly name/identifier for this connection context
• -ApiKey - (Optional) The API key as a SecureString. If not provided, prompt the user
• -PassThru - Return the context object after creation
• -Silent - Suppress informational output

Example:

# Interactive flow - opens browser and prompts for API key
Connect-PowerShellGallery -Name 'MyAccount'

# Programmatic flow - provide API key directly
Connect-PowerShellGallery -Name 'CIAccount' -ApiKey $secureApiKey

2. Test-PowerShellGalleryAccess Function

Create a function that validates the stored API key by testing access to the PowerShell Gallery API.

Behavior:

• Use the stored context to authenticate
• Query the PowerShell Gallery API to retrieve packages published by the account
• Return information about the account's published packages

Parameters:

• -Context - (Optional) The context to use. If not specified, use the default context

Example:

# Test access using the default context
Test-PowerShellGalleryAccess

# Test access using a specific context
Test-PowerShellGalleryAccess -Context 'MyAccount'

3. Supporting Functions

Implement supporting functions following the pattern from the GitHub module:

• Get-PowerShellGalleryContext - Retrieve stored contexts
• Switch-PowerShellGalleryContext - Set the default context
• Disconnect-PowerShellGallery - Remove a stored context
• Get-PowerShellGalleryAccessToken - Retrieve the API key (as SecureString or plain text with -AsPlainText)

Implementation Details

Context Storage Pattern

Reference the GitHub module's implementation:

# Module-level variable for vault configuration
$script:PowerShellGallery = @{
 ContextVault = 'PSModule.PowerShellGallery'
 DefaultConfig = @{
 ID = 'Module'
 DefaultContext = $null
 GalleryUrl = 'https://www.powershellgallery.com'
 ApiUrl = 'https://www.powershellgallery.com/api/v2'
 }
}

Context Object Structure

@{
 ID = 'MyAccount' # Unique identifier
 Name = 'MyAccount' # Display name
 ApiKey = <SecureString> # The API key (encrypted by Context module)
 GalleryUrl = 'https://www.powershellgallery.com'
 ConnectedAt = <DateTime>
}

Wrapper Functions Pattern

From the Context module's best practices:

function Set-PowerShellGalleryContext {
 param(
 [Parameter(Mandatory)]
 [string] $ID,
 
 [Parameter(Mandatory)]
 [object] $Context
 )
 
 Set-Context -ID $ID -Vault $script:PowerShellGallery.ContextVault -Context $Context
}

function Get-PowerShellGalleryContext {
 param(
 [string] $ID = '*'
 )
 
 Get-Context -ID $ID -Vault $script:PowerShellGallery.ContextVault
}

Dependencies

• Context module (for secure storage)
• PowerShell Gallery NuGet API v2/v3

References

• Context Module - Secure context storage
• GitHub Module - Reference implementation
  • Connect-GitHubAccount
  • Set-GitHubContext
  • Get-GitHubContext
• PowerShell Gallery API Keys

Testing

Build out tests using the APIKEY secret available in the workflow. We need the function be able to work in a non-interactive way to make sure this works.
