PowerShell script to create self signed certificate.

$FilePath = 'C:\Users\Dipes\Desktop\certificates\abc'
$StoreLocation = 'CurrentUser' # be aware that LocalMachine requires elevated privileges
$expirationYears = 1

$SubjectName = $tenant_id + '.' + $client_id
$cert_password = $client_id

$pfxFileName = $SubjectName + '.pfx'
$cerFileName = $SubjectName + '.cer'

$PfxFilePath = $FilePath + $pfxFileName
$CerFilePath = $FilePath + $cerFileName

$CertBeginDate = Get-Date
$CertExpiryDate = $CertBeginDate.AddYears($expirationYears)

$SecStringPw= ConvertTo-SecureString -String $cert_password -Force -AsPlainText

$Cert = New-elfSignedCertificate -DnsName $SubjectName -CertStoreLocation "cert:\$StoreLocation\My" -NotBefore $CertBeginDate -NotAfter $CertExpiryDate -KeySpec Signature

Export-PfxCetificate -cert $Cert -FilePath $PFXFilePath -Password $SecStringPw
Export-Certificate -cert $Cert -FilePath $CerFilePath
