Openssl Generate Private Key From Existing Certificate
This tutorial is geared towards OpenSSL and generating a Certficiate Authority dedicated to the Cracklord environment. You are welcome to use an existing PKI infrastructure to generate the Queue Server and Resource certificates. There is one thing to note when creating the Queue Server certificate, however. The Queue Server certificate must have the ability to do both Server and Client Authentication. This tutorial does this through OpenSSL extensions, but an existing PKI environment should have the mechanisms to do this as well. Feel free to add specific instructions for Windows or any other PKI tools you might use.
Next, you'll create a server certificate using OpenSSL. Create the certificate's key. Use the following command to generate the key for the server certificate. Openssl ecparam -out fabrikam.key -name prime256v1 -genkey Create the CSR (Certificate Signing Request) The CSR is a public key that is given to a CA when requesting a certificate. How to Generate a CSR Using Apache OpenSSL. For starters, you’ll need to have SSH access at server- and root-level permissions in order to generate your CSR and Private Key. Using Putty, connect to Apache Server SSH and login as root. Type the command below when prompted.
Public Private Key Encryption
##Creating the Certificate Authority Private Key and CertificateWe first need create a private key for the CA.
We next must create the CA certificate to be used to validate signed certificates.
You will be prompted to answer some questions. Some example answers are provided below.
/tee-generate-a-public-key.html. ##Creating the Queue Server Private Key and CertificateBefore we create and sign the Queue Server key we need to configure the proper extensions to mark the certificate as User Authentication as well as Server Authentication. Create a file called openssl-ext.conf with the following content.
Now that this file exist we can need to generate a private key for the Queue Server.
/ssh-host-key-generation-ubuntu.html. We now need to create a certificate signing request to sign with the CA we previously created.
We now need to sign the request, while including the signing extensions we created earlier. The following command will do this.
We now have all the keys required to sign new Resource certificates as they are added and to provide mutual authentication from the Queue.
Instructions for generating certificates and private keys for the Resource can be found here.
