Hi,  
i use ACMESharp via power shell to create multiple domains per certificates  
How can i rewrite this code below?

```
#install-Module -Name ACMESharp

import-module ACMESharp

$email = "mailto:admin@admin.com"
$iissitename = "websitename"
$certname = "aaa15$(get-date -format yyyy-MM-dd--HH-mm)"
$pfxfile = "C:\Certs\03\pfx\$certname.pfx"

$initializevault = $FALSE
$createregistration = $FALSE
$createalias = $TRUE

$domains = @(<...list of domains...>			
	)

$aliases = @()

# Change to the Vault folder
cd C:\ProgramData\ACMESharp\sysVault

# First time on the machine - intiialize vault
if($initializevault) 
{
    Initialize-ACMEVault
}

Get-ACMEVault

if($createregistration) 
{
    # Set up new 'account' tied to an email address
     New-AcmeRegistration -Contacts "$email" -AcceptTos
}
For ($i=0; $i -lt $domains.Length; $i++) {
	 
		$aliases += @($domains[$i]+$(get-date -format yyyyMMddHHmm))
		# Associate a new site 
		New-AcmeIdentifier -Dns $domains[$i] -Alias $aliases[$i]
		#New-ACMEIdentifier -Dns $domain2 -Alias $alias2

		# Prove the site exists and is accessible => (This creates files at .well-known\acme-challenge folder)
		Complete-ACMEChallenge $aliases[$i] -ChallengeType http-01 -Handler iis -HandlerParameters @{WebSiteRef="$iissitename"} -Force
		#Complete-ACMEChallenge $alias2 -ChallengeType http-01 -Handler iis -HandlerParameters @{WebSiteRef="$iissitename"} -Force

		# Validate site
		Submit-ACMEChallenge $aliases[$i] -ChallengeType http-01 -Force
		#Submit-ACMEChallenge $alias2 -ChallengeType http-01 -Force

		# check until valid or invalid - pending =>(Just check the status field)
		Update-ACMEIdentifier $aliases[$i] -ChallengeType http-01
		#Update-ACMEIdentifier $alias2 -ChallengeType http-01 
	
}
```

Hi,

You can open an issue with ACMESharp’s repo in the link below as they are more familiar with their code.
