Oct 09, 2019 How to Generate & Use Private Keys using OpenSSL's Command Line Tool These commands generate and use private keys in unencrypted binary (not Base64 “PEM”) PKCS#8 format. The PKCS#8 format is used here because it is the most interoperable format when dealing with software that isn't based on OpenSSL. The CSR (Certificate Signing Request) is essential for the issuing of the certificate, as it contains the public key. The public key will be generated by your web host or the administrators of the servers, on which the domain runs that you wish to secure with the SSL certificate. Apr 12, 2020 Now to create SAN certificate we must generate a new CSR i.e. Certificate Signing Request which we will use in next step with openssl generate csr with san command line. root@centos8-1 certs# openssl req -new -key server.key.pem -out server.csr You are about to be asked to enter information that will be incorporated into your certificate request. You will also be prompted for information to populate the CSR. At the command line, type: $ openssl req -new -key /path/to/wwwservercom.key -out /path/to/wwwservercom.csr. This will fire up OpenSSL, instruct it to generate a certificate signing request, and let it know to use a key we are going to specify – the one we just created, in.
Sep 11, 2018 You apply by generating a CSR with a key pair on your server that would, ideally, hold the SSL certificate. The CSR contains crucial organization details which the CA verifies. Generate a CSR and key pair locally on your server. The key pair consists of a public and private key.
When generating a key, you have to decide three things: the key algorithm, the key size, and whether to use a passphrase.
Key Algorithm

For the key algorithm, you need to take into account its compatibility. For this reason, we recommend you use RSA. However, if you have a specific need to use another algorithm (such as ECDSA), you can use that too, but be aware of the compatibility issues you might run into.

Key Size
For the key size, you need to select a bit length of at least 2048 when using RSA and 256 when using ECDSA; these are the smallest key sizes allowed for SSL certificates. Unless you need to use a larger key size, we recommend sticking with 2048 with RSA and 256 with ECDSA.
Note: In older versions of OpenSSL, if no key size is specified, the default key size of 512 is used. Any key size lower than 2048 is considered unsecure and should never be used.

Passphrase

For the passphrase, you need to decide whether you want to use one. If used, the private key will be encrypted using the specified encryption method, and it will be impossible to use without the passphrase. Because there are pros and cons with both options, it's important you understand the implications of using or not using a passphrase. In this guide, we will not be using a passphrase in our examples.
