function ConvertTo-X509Certificate2
{
    <#
.SYNOPSIS
This function will output a X509Certificate2 certificate.
.DESCRIPTION
Because Linux does not have the Cert: provider (Get-PsProvider), we have to find a way to use the provided certificate on all platforms and X509
is a solution. This function will inject several format (cer,crt,pem,pfx) to expose the result in a standardized way.
.PARAMETER PfxPath
Specify path of a pfx file.
.PARAMETER PemPath
Specify path of a pem file.
.PARAMETER CerPath
Specify path of a cer file.
.PARAMETER CrtPath
Specify path of a crt file.
.PARAMETER Password
Specify password of a pfx file.
.PARAMETER PrivateKeyPath
Specify path of a decrypted private key.
.PARAMETER KeyVaultCertificatePath
Specify path of a specific certificate version hosted on Azure Key Vault.
.PARAMETER AccessToken
Specify an access token to contact the associated Key Vault.
.PARAMETER APIVersion
Specify the API version regarding Keyvault API for now the default value is 7.3.
.PARAMETER ExportPrivateKey
Specify you want to extract from Key Vault the certificate with the Private key.
.EXAMPLE
 
$PubCert = ConvertTo-X509Certificate2 -CerPath ./scomnewbie.cer
 
Will generate a X509Certificate2 without private key from a cer file.
 
.EXAMPLE
 
$PubCert = ConvertTo-X509Certificate2 -CerPath ./scomnewbie.crt
 
Will generate a X509Certificate2 without private key from a crt file.
 
.EXAMPLE
 
$PrivCert = ConvertTo-X509Certificate2 -PfxPath ./scomnewbie.pfx -Password $(ConvertTo-SecureString -String "exportpassword" -AsPlainText -Force)
$PrivCert.PrivateKey
 
Will generate a X509Certificate2 with private key from a pfx file.
 
.EXAMPLE
 
$PrivCert = ConvertTo-X509Certificate2 -PemPath ./scomnewbie2.pem -PrivateKeyPath ./privatekey_rsa.key
$PrivCert.PrivateKey
 
Will generate a X509Certificate2 with private key from a pem file.
 
.EXAMPLE
 
$CertURL = 'https://<myvault>.vault.azure.net/certificates/test/5d69153b75214245ab72fa21b9c06bfb'
$KVToken = (Get-AzAccessToken -Resource "https://vault.azure.net").Token #Once authenticated to Azure
ConvertTo-X509Certificate2 -KeyVaultCertificatePath $CertURL -AccessToken $KVToken
 
Will generate a X509Certificate2 with public key from a certificate hosted in Key Vault.
.EXAMPLE
 
$CertURL = 'https://<myvault>.vault.azure.net/certificates/test/5d69153b75214245ab72fa21b9c06bfb'
$KVToken = (Get-AzAccessToken -Resource "https://vault.azure.net").Token #Once authenticated to Azure
ConvertTo-X509Certificate2 -KeyVaultCertificatePath $CertURL -AccessToken $KVToken -ExportPrivateKey
 
Will generate a X509Certificate2 with private key from a certificate hosted in Key Vault.

    <#
    .SYNOPSIS
    This function will interact with MSAL.
    .DESCRIPTION
    Use this function to generate JWT Entra tokens. By default the token cache will be in memory.
    .PARAMETER ClientCredentialFlowWithSecret
    The ClientCredentialFlowWithSecret parameter defines you want to generate an entra token with the client credential flow with secrets.
    .PARAMETER ClientCredentialFlowWithCertificate
    The ClientCredentialFlowWithCertificate parameter defines you want to generate an entra token with the client credential flow with certificates.
    .PARAMETER PublicAuthorizationCodeFlow
    The PublicAuthorizationCodeFlow parameter defines you want to generate an entra token with the Authorization Code flow with PKCE. No secrets are required.
    .PARAMETER DeviceCodeFlow
    The DeviceCodeFlow parameter defines you want to generate an entra token with the Device code flow. No secrets are required.
    .PARAMETER WAMFlow
    The WAMFlow parameter defines you want to generate an entra token with the Windows WAM (Web Account Manager). No secrets are required.
    .PARAMETER OnBehalfFlowWithSecret
    The OnBehalfFlowWithSecret parameter defines you want to generate an entra token with the On behalf flows with secrets.
    .PARAMETER OnBehalfFlowWithCertificate
    The OnBehalfFlowWithCertificate parameter defines you want to generate an entra token with the On behalf flows with certificates.
    .PARAMETER FederatedCredentialFlowWithAssertion
    The FederatedCredentialFlowWithAssertion parameter defines you want to generate an entra token with the federated credential authentication method. A token assertion is required.
    .PARAMETER UserAssertion
    The UserAssertion parameter defines the token you want to use in both the OBO flow or the federated credential flow.
    .PARAMETER SystemManagedIdentity
    The SystemManagedIdentity parameter defines the token you want to generate an entra token with the system managed identity.
    .PARAMETER UserManagedIdentity
    The UserManagedIdentity parameter defines the token you want to generate an entra token with the user managed identity.
    .PARAMETER ClientId
    The ClientId parameter defines the client Id (application Id) you want to use to generate a token.
    .PARAMETER ClientSecret
    The ClientSecret parameter defines the client secret you want to use in your authentication flow.
    .PARAMETER ClientCertificate
    The ClientCertificate parameter defines the client certificate you want to use in your authentication flow.
    .PARAMETER WithoutCaching
    The WithoutCaching parameter defines the you want to force a token refresh instead of using the MSAL cache.
    .PARAMETER AzureCloudInstance
    The AzureCloudInstance parameter defines the Azure environment you plan to consume. By default, the module target Azure public.
    .PARAMETER TenantId
    The TenantId parameter defines the Entra tenant Id. If you don't specificy this parameter, the common authority will be used (multi-tenants applications)
    .PARAMETER RedirectUri
    The RedirectUri parameter defines the redirect uri required for several public workflow. By default this parameter equal http://localhost.
    .PARAMETER Resource
    The Resource parameter defines the resource you want to consume. A scope is composed of a resource and a permission. This parameter is pre-filled with Azure audiences like Graph API, KeyVault or Custom (your API)
    .PARAMETER CustomResource
    The CustomResource parameter defines your custom resource you exposed in Entra (api://<...>). You have to use it in addition of the Custom Resource parameter value.
    .PARAMETER Permissions
    The Permissions parameter defines the permissions you request. This is usually what is after api://<...>/<Permission> or with Graph API @("User.Read","Group.Read"). the combinaison of Resource and permission create the scope.
    .PARAMETER ExtraScopesToConsent
    The ExtraScopesToConsent parameter defines the extra scopes you need following the Entra limitation where you can call only one resource per call. Thi parameter is useful when you need Graph API and ARM token.
    .EXAMPLE
 
    $HashArguments = @{
        ClientId = $clientId
        ClientSecret = $ClientSecret
        TenantId = $TenantId
        Resource = 'GraphAPI'
    }
    Get-EntraToken -ClientCredentialFlowWithSecret @HashArguments
 
    This command will generate a token to access Graph API scope with all application permissions assign to this app registration. The token is stored in memory cache managed by MSAL.
    .EXAMPLE
 
    $HashArguments = @{
        ClientId = $clientId
        TenantId = $TenantId
        RedirectUri = 'http://localhost'
        Resource = 'GraphAPI'
        Permissions = @('user.read','group.read.all')
        ExtraScopesToConsent = @('https://management.azure.com/user_impersonation')
        verbose = $true
    }
 
    Get-EntraToken -PublicAuthorizationCodeFlow @HashArguments
 
    This command will generate a token to access Graph API scope with all application permissions added in the request. In addition, the request will do a second call to Entra to generate a token to access the ARM resource. The token is stored in memory cache managed by MSAL.
    .EXAMPLE
 
    Get-EntraToken -DeviceCodeFlow -ClientId $ClientId -TenantId $TenantId -Resource GraphAPI -Permissions @('user.read')
 
    This command will generate a token to access Graph API (user.read) scope with the default redirect uri value which is 'http://localhost'
