A self-signed certificate it's very easy to create and helps on with local development and testing.
With a Single Line of PowerShell code we create a certificate.
First, open the
PowerShell as Administrator and run the following command:
New-SelfSignedCertificate ` –DnsName <DNS-Name> ` -CertStoreLocation "cert:\LocalMachine\My"
The default expiration is 1 year. If you want a custom expiration date use option
New-SelfSignedCertificate ` –DnsName <DNS-Name> ` -CertStoreLocation "cert:\LocalMachine\My" ` -NotAfter [System.DateTime]::AddYears(3)
That is it. Done!! The certificate was created and stored in our
Certificate Store of Windows.
Note the parameter "CertStoreLocation", this is where the cert will be stored. cert:\LocalMachine means Local Machine Cert store.
Now let's export it as a
.pfxfile into a local directory.
In the same PowerShell window run the following commands.
#create a password for our cert $pwd = ConvertTo-SecureString -String "SOME-PASSWORD" -Force -AsPlainText #finds the certificate in our local store $cert = Get-ChildItem -Path cert:\LocalMachine\my | where Subject -eq "CN=rmauro.dev" #exports the certificate to temp directory Export-PfxCertificate -FilePath c:\temp\rmauro.dev.pfx -Password $pwd -Cert $cert
In my scenario, the cert name is rmauro.dev. Change it to yours.
Check the directory temp to find the certificate -
