How to create Self signed certificate with PowerShell?

Question : How to Create self signed certificate using PowerShell?

Solution: A self-signed certificate is a certificate we sign with our own private key for testing purposes. Self signed certificate can be created with PowerShell using New-selfsignedcertificate. 

New-selfsignedcertificate -certstorelocation cert:\localmachine\my -dnsname iafs.itsamar.local

By default, a self-signed certificate is generated with the following settings:

• Cryptographic algorithm: RSA
• Key length: 2048 bit
• Acceptable key usage: Client Authentication and Server Authentication;
• Validity period: 1 year.

To export the certificate as pfx file,

$certificate = New-SelfSignedCertificate -certstorelocation cert:\localmachine\my -dnsname iadf.https://amar365.com

$pwrd = ConvertTo-SecureString -String `P@ssw0rd123′ -Force -AsPlainText

$pathloc = ‘cert:\localMachine\my\’ + $certificate.thumbprint

$certThumbprint = $certificate.Thumbprint

Thumbprint info can be stored as variable to use it later.
