Select Local computer. Indicates that the new certificate includes available encryption algorithms to a Secure/Multipurpose Internet Mail Extensions (S/MIME) capabilities extension. If the private key is managed by a legacy CSP, the value is KeyExchange or Signature. You are probably reading this article because for some reason, you need to create a self-signed certificate with Windows. The PKI Client can be used to generate a self-signed certificate. All Rights Reserved. Guiding you with how-to advice, news and tips to upgrade your tech life. As far as we know, the processes for Windows 11 are identical.

Your application running in Azure Automation will use the private key to initiate authentication and obtain access tokens for calling Microsoft APIs like Microsoft Graph. This example creates a copy of the certificate specified by the CloneCert parameter and puts it in the computer MY store. This parameter does not apply to providers that do not support security descriptors on private keys, including the smart card CSP and smart card KSP. Run the following command to generate a PKCS #10 certificate signing request (CSR) and create a CSR (.csr) file, replacing the following placeholders with their corresponding values. The self-signed certificate you created following the steps above has a limited lifetime before it expires. If the value of the relative distinguished name contains commas, separate each subject relative distinguished name with a semicolon (;).

The $cert variable in the previous command stores your certificate in the current session and allows you to export it. Self-signed certificates are widely used in testing environments and they are excellent alternatives to purchasing and renewing yearly certifications. The application that initiates the authentication session requires the private key while the application that confirms the authentication requires the public key. It is a best practice to also have this certificate set in the trusted root as well. Some acceptable values include: Specifies the name of the smart card reader on which to store the private key for the new certificate. Other options would require more typing, for sure. The self-signed certificate will have the following configuration: To customize the start and expiry date and other properties of the certificate, refer to New-SelfSignedCertificate.
