<# .SYNOPSIS .DESCRIPTION .PARAMETER CN CommonName for the new certificate .PARAMETER OpenSsl Use OpenSSL to generate certificates (usefull for custom extensions) .PARAMETER SelfSigned Generate a self-signed certificate .PARAMETER ClientAuth (default = true) Use this certificate for Client-side authentication .PARAMETER ServerAuth Use this certificate for Server-side authentication .PARAMETER ca The name of Certificate Authority that will sign this certificate (reqires a private key file) .PARAMETER pass Use this password to protect the new certificate .EXAMPLE .\New-Cert.ps1 my-apiclient -ca legimiCA -ClientAuth .NOTES XXX #> function New-Cert { param( [parameter(mandatory=$true)] [string] $CN, [switch] [bool] $OpenSsl = $false, [switch] [bool] $selfSigned = $false, [switch][bool] $ClientAuth = $true, [switch][bool] $RootAuth = $false, [switch][bool] $ServerAuth = $false, [string] $ca = $null, [string] $pass = "", [switch] [bool] $force, $days = 365 ) ipmo require req process $basedir = "${env:ProgramFiles(x86)}\Windows Kits\8.1\bin\x64" $env:Path = "$env:Path;$basedir" $useOpenssl = $OpenSsl $certName = $CN.Replace("*", "wildcard") $clientAuth = !$ServerAuth $EKUServerAuth = "1.3.6.1.5.5.7.3.1" $EKUClientAuthentication = "1.3.6.1.5.5.7.3.2" $EKU = $EKUClientAuthentication $openssl_eku = "clientAuth" $openssl_ext = "usr_cert" if ($ServerAuth) { $EKU = $EKUServerAuth $openssl_eku = "" $openssl_ext = "server" } if ([string]::IsNullOrEmpty($ca)) { if (!$selfSigned -and !$rootauth) { throw "no ca name given.
