Import a PFX certificate into Windows Server and change its FriendlyName property in PowerShell

# Import a PFX certificate into Windows Server and change its 
# FriendlyName property in PowerShell.
# 
# Using Get-Credential here ensures the password doesn't get saved
# into PowerShell's history file.
#   -- see https://www.saotn.org for more PowerShell goodness :)
# 

$CommonName = "CHANGEME"
$CertFileName = "CHANGEME.pfx"
$mypwd = Get-Credential -UserName "${CommonName} SSL certificate" -Message 'Enter password below'
$params = @{
  FilePath = "\SSL-certs\${CommonName}\${CertFileName}"
  CertStoreLocation = 'Cert:\LocalMachine\My'
  Password = $mypwd.Password
}

$cert = Import-PfxCertificate @params

# Update the certificate FriendlyName with the CommonName string and
# year it expires
$cert.FriendlyName = "${CommonName} expires $((Get-Date).AddYears(1)).ToString("yyyy")"

If the last line ($cert.FriendlyName = ...) doesn't work, you can use:

string]$thumbprint = $cert.Thumbprint
(Get-ChildItem -Path Cert:\LocalMachine\My\${thumbprint}).FriendlyName = "${certificatename} 2024"
