function Get-YcRequiredModules { <# .SYNOPSIS The Get-YcRequiredModules function checks for the availability and import status of a specified PowerShell module and attempts to import it if necessary. .DESCRIPTION The Get-YcRequiredModules function takes the name of several PowerShell modules as input and verifies its installation and import status. If the module is not installed, it alerts the user to install it. If the module is installed but not imported, the function attempts to import it. If importing fails, an error message is displayed. .PARAMETER moduleNames The moduleName parameter is a mandatory array of string specifying the name of the modules to check for. .INPUTS The function does not accept any pipeline input. .OUTPUTS The function outputs a message indicating whether the specified module is installed, imported, or if an error occurred during importing. .EXAMPLE The following example shows how to use the Get-YcRequiredModules function to check and manage the status of a module: PS> Get-YcRequiredModules -moduleName "Az.Accounts" #> param ( [Parameter(Mandatory=$true, Position = 0)] [ValidateNotNullOrEmpty()] [string[]]$moduleNames ) Foreach ($Module in $ModuleNames) { # Check if the module is installed $moduleInstalled = Get-Module -ListAvailable -Name $module if (-not $moduleInstalled) { $message = "The required module '$module' is not installed.

The function accepts an optional log name, defaulting to "Application", and an optional source name to be associated with the log. If the source does not exist, it is created in the specified log. .PARAMETER logName The logName parameter is an optional string specifying the name of the log to associate the source with. It defaults to "Application". .PARAMETER source The source parameter is a mandatory string specifying the source name to be associated with the log. .INPUTS The function does not accept any pipeline input. .OUTPUTS The function does not output anything directly, but it initializes logging by ensuring a source exists. .EXAMPLE The following example shows how to initialize event logging by setting up a source in the "Application" log: PS> Initialize-YcEventLogging -source "MyAppSource" #> param ( [Parameter(Mandatory=$false, Position = 0)] [ValidateNotNullOrEmpty()] [string]$logName = "Application", [Parameter(Mandatory=$true, Position = 1)] [string]$source = "YcEventLog" ) if (($IsAdmin = Get-YcCurrentUserType) -eq "Administrator") { if (![System.Diagnostics.EventLog]::SourceExists($source)) { [System.Diagnostics.EventLog]::CreateEventSource($source, $logName) } } else { if (![System.Diagnostics.EventLog]::SourceExists($source)) { $message = ("Source: "+$source+" does not exist on this machine.

The default value is 1001. .INPUTS The function does not accept any pipeline input. .OUTPUTS The function does not return any output but writes an event log entry. .EXAMPLE The following example shows how to write a new event log entry: PS> Write-YcEventLog -message "Application started successfully." #> param ( [Parameter(Mandatory=$true, Position = 0)] [ValidateNotNullOrEmpty()] [string]$message, [Parameter(Mandatory=$false, Position = 1)] [string]$logName = "Application", [Parameter(Mandatory=$false, Position = 2)] [string]$source = "YcEventLog", [Parameter(Mandatory=$false, Position = 3)] [ValidateSet("Information", "Warning", "Error")] [string]$entryType = "Information", [Parameter(Mandatory=$false, Position = 4)] [int]$eventId = 1001 ) $message = Protect-YcLogMessage($message) Write-EventLog -LogName $logName -Source $source -EntryType $entryType -EventId $eventId -Message $message } function Write-YcLogFile { <# .SYNOPSIS The Write-YcLogFile function writes a message to a specified log file, organizing logs by date and source. .DESCRIPTION The Write-YcLogFile function writes a log message to a specified directory and file. It accepts mandatory parameters for the log message, log directory, and source. The function checks if the log directory and file exist, creating them if necessary. The message is processed through the `Protect-LogMessage` function, and a timestamped log entry is appended to the file, organizing logs by date and source. If the log file exceeds a specified size, it is rotated and archived. .PARAMETER message The message parameter is a mandatory string specifying the content of the log entry. .PARAMETER logDirectory The logDirectory parameter is a mandatory string specifying the directory to store log files. .PARAMETER source The source parameter is a mandatory string specifying the source of the log entry. .PARAMETER maxLogSize The maxLogSize parameter is an optional integer specifying the maximum log file size in megabytes before rotating.

The default value is "WindowsCredentialStore". .PARAMETER AzKeyVaultClientId The AzKeyVaultClientId parameter is an optional string specifying the client ID for connecting to Azure Key Vault. .PARAMETER AzKeyVaultTenantId The AzKeyVaultTenantId parameter is an optional string specifying the tenant ID for connecting to Azure Key Vault. .PARAMETER AzKeyVaultName The AzKeyVaultName parameter is an optional string specifying the name of the Azure Key Vault. .PARAMETER AzKeyVaultCertThumbprint The AzKeyVaultCertThumbprint parameter is an optional string specifying the certificate thumbprint for Azure Key Vault authentication. .PARAMETER AsPlainText The AsPlainText parameter is an optional boolean indicating whether to return the secret as plain text. The default value is false. .PARAMETER SupressErrors The SupressErrors parameter is an optional boolean indicating whether to suppress error messages. The default value is false. .INPUTS The function does not accept any pipeline input. .OUTPUTS The function returns the retrieved secret or an error message. .EXAMPLE The following example shows how to retrieve a secret from the Windows Credential Store: PS> Get-YcSecret -secretName "MyAppSecret" #> param ( [Parameter(Mandatory=$true, Position = 0)] [ValidateNotNullOrEmpty()] [string]$secretName, [Parameter(Mandatory=$false, Position = 1)] [ValidateSet("WindowsCredentialStore", "EnvironmentVariable", "AzureKeyVault")] [string]$SecretLocation = "WindowsCredentialStore" , [Parameter(Mandatory=$false, Position = 2)] [string]$AzKeyVaultClientId, [Parameter(Mandatory=$false, Position = 3)] [string]$AzKeyVaultTenantId, [Parameter(Mandatory=$false, Position = 4)] [string]$AzKeyVaultName, [Parameter(Mandatory=$false, Position = 5)] [string]$AzKeyVaultCertThumbprint, [Parameter(Mandatory=$false, Position = 6)] [bool]$AsPlainText = $false, [Parameter(Mandatory=$false, Position = 7)] [bool]$SupressErrors = $false ) switch ($SecretLocation) { WindowsCredentialStore { try { $storedCredential = Get-StoredCredential -Target $secretName # Check if a credential was returned if ($null -ne $storedCredential) { return $storedCredential.Password } else { $ErrorMessage = "Get-LocalSecret @ "+(Get-Date)+": ERROR: No credential found for the given Name "+$secretName+" Check if the credentialName is correct or if the credential exists in the Windows Credential Store." if ($SupressErrors -eq $false) { Write-Host $ErrorMessage -ForegroundColor Red } } } catch { $ErrorMessage = "Get-LocalSecret @ "+(Get-Date)+": ERROR: Could not retrieve locally stored Secret with name: "+$sercetName+" Error Details: "+$_.Exception.Message Write-Host $ErrorMessage -ForegroundColor Red } } EnvironmentVariable { If (Test-Path "Env:$secretName") { $storedCredential = (Get-Item -Path "Env:$secretName").Value If (-not [string]::IsNullOrEmpty($storedCredential)) { return $storedCredential } else { Write-Host "ERROR: Environment variable '$secretName' is null or empty." -ForegroundColor Red } } else { Write-Host "ERROR: Environment variable '$Name' not set." -ForegroundColor Red } } AzureKeyVault { $requiredModules = "Az.Accounts", "Az.KeyVault" Get-YcRequiredModules $requiredModules # Checking in LocalMachine store $certCheckLocalMachine = Get-ChildItem -Path Cert:\LocalMachine\My | Where-Object { $_.Thumbprint -eq $AzKeyVaultCertThumbprint } # Checking in CurrentUser store $certCheckCurrentUser = Get-ChildItem -Path Cert:\CurrentUser\My | Where-Object { $_.Thumbprint -eq $AzKeyVaultCertThumbprint } # If the certificate is not found in either store, throw an exception if (-not $certCheckLocalMachine -and -not $certCheckCurrentUser) { throw "Certificate with thumbprint $AzKeyVaultCertThumbprint not found in either LocalMachine or CurrentUser store.
