Otherwise Follow the instructions H ow To Export an SSL Certificate With Private Key (pfx) Using MMC On Windows to get that intermediate into the pfx file. To Export the SSL Certificate as a pfx file from the IIS manager perform the following. Go to Start Administrative Tools Internet Information Services (IIS). Apr 05, 2018 This will create a self-signed certificate valid for a year with a private key. It is only for “localhost”. Yes, they are a training company but they also have some neat utilities. Apr 26, 2019 Certificates are exportable with the private key,so you can create the certificate on one computer and export it to another. Run CertLM.msc to open Certificate Manager for Local Computer directly or CertMgr.msc for the Current User Certificate should be trusted on all computers that have your Root CA’s cert installed. Oct 29, 2017 First of all we need a certificate. This certificate will include a private key and public key. With the private key we can decrypt data. With the public key we can encrypt data. This means if someone has my public key (I can give it to someone without any worries) he can encrypt data which is addressed to me. Powershell: how to set up a public/private key pair using Windows and puttygen.exe. Download puttygen.exe, open it and click Generate to generate a private/public key pair. I set the number of key bits to 4096. Then export the private key for use with the SSH-Sessions module (has to be in OpenSSH format – the Putty key format will not work as of 2013-09-14).
KeyVault generated certificate with exportable private key. I'm attempting to create a self signed certificate in KeyVault using the 'Self' issuer. However, when getting the certificate back it doesn't appear to have a private key. Nov 02, 2014 Self-Signed Certificate can be used widely in test, development, Local Web or Cloud Web Sites. This article will introduce a method to quickly generate Self-Signed Certificate, automatically export private key, and install the cert under LocalMachineMy and LocalMachineRoot on.
The New-SelfSignedCertificate cmdlet creates a self-signed certificate for testing purposes.Using the CloneCert parameter, a test certificate can be created based on an existing certificate with all settings copied from the original certificate except for the public key.The cmdlet creates a new key of the same algorithm and length.
Delegation may be required when using this cmdlet with Windows PowerShell remoting and changing user configuration.
EXAMPLE 1
This example creates a self-signed SSL server certificate in the computer MY store with the subject alternative name set to www.fabrikam.com, www.contoso.com and Subject and Issuer name set to www.fabrikam.com.
EXAMPLE 2
This example creates a copy of the certificate specified by the CloneCert parameter and puts it in the computer MY store.
EXAMPLE 3
This example creates a self-signed S/MIME certificate in the user MY store.The certificate uses the default provider, which is the Microsoft Software Key Storage Provider.The certificate uses an RSA asymmetric key with a key size of 2048 bits.This certificate has the subject alternative names of patti.fuller@contoso.com as RFC822 and pattifuller@contoso.com as Principal Name.
This command does not specify the NotAfter parameter.Therefore, the certificate expires in one year.
EXAMPLE 4
This example creates a self-signed client authentication certificate in the user MY store.The certificate uses the default provider, which is the Microsoft Software Key Storage Provider.The certificate uses an RSA asymmetric key with a key size of 2048 bits.The certificate has a subject alternative name of pattifuller@contoso.com.

The certificate expires in one year.
EXAMPLE 6
This example creates a self-signed client authentication certificate in the user MY store.The certificate uses the Microsoft Platform Crypto Provider.This provider uses the Trusted Platform Module (TPM) of the device to create the asymmetric key.The key is an RSA 2048-bit key that cannot be exported.The subject alternative name is pattifuller@contoso.com.The certificate expires in one year.
EXAMPLE 7
This example creates a self-signed client authentication certificate in the user MY store.The certificate uses the default provider, which is the Microsoft Software Key Storage Provider.The certificate uses an RSA asymmetric key with a key size of 2048 bits.The subject alternative name is pattifuller@contoso.com.
This command specifies a value for NotAfter.The certificate expires in six months.
EXAMPLE 8
This example creates a self-signed S/MIME certificate in the user MY store.The certificate uses the default provider, which is the Microsoft Software Key Storage Provider.The certificate uses an RSA asymmetric key with a key size of 2048 bits.This certificate has the subject alternative names of patti.fuller@contoso.com and pattifuller@contoso.com both as RFC822.
