C# код для доступа к API MS GRAPH (В ЭТОМ СЛУЧАЕ INTUNE) и использования сертификатов для аутентификации. Это основано на статье, которую можно найти здесь: https://laurakokkarinen.com/authenticating-to-office-365-apis-with-a-certificate-step-by-step/comment-page-2/#comment -697
Первый - это скрипт powershell для генерации сертификата. Тогда есть интерфейс регистратора и конфигуратор для чтения из файла JSON. Вследствие этого существует ЧИТАТЕЛЬ, использующий асинхронные вызовы для аутентификации с помощью API и получения взамен токена.
# Run this script as an administrator
# --- config start
$dnsName = "mytenant.sharepoint.com" # Your DNS name
$password = "F1exera!" # Certificate password
$folderPath = "C:\InTuneCertificate" # Where do you want the files to get saved to? The folder needs to exist.
$fileName = "InTune" # What do you want to call the cert files? without the file extension
$yearsValid = 10 # Number of years until you need to renew the certificate
# --- config end
$certStoreLocation = "cert:\LocalMachine\My"
$expirationDate = (Get-Date).AddYears($yearsValid)
$certificate = New-SelfSignedCertificate -DnsName $dnsName -CertStoreLocation $certStoreLocation -NotAfter $expirationDate -KeyExportPolicy Exportable -KeySpec Signature
$certificatePath = $certStoreLocation + '\' + $certificate.Thumbprint
$filePath = $folderPath + '\' + $fileName
$securePassword = ConvertTo-SecureString -String $password -Force -AsPlainText
Export-Certificate -Cert $certificatePath -FilePath ($filePath + '.cer')
