May 13, 2019 There are two steps involved in generating a certificate signing request (CSR). First, you have to generate a private key, and then generate CSR using that private key. Step 1: Generate a private key. Enter the following command in the Terminal with sudo to generate a private key using RSA algorithm with a key length of 2048 bits. Mar 30, 2015 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 fact. Note that a certificate signing request always has a file name ending in.csr. How can I find the private key for my SSL certificate. If you just got an issued SSL certificate and are having a hard time finding the corresponding private key, this article can help you to find that one and only key for your certificate.

How to generate a CSR using Java Keytool
**NOTE: You must generate a new keystore through this process. If you try to install a new certificate to an old keystore your certificate will not work properly. Backup and remove any old keystores if necessary before beginning this process.
Recommended: Save yourself some time by using our new Java Keytool CSR Wizard to create your CSR with Keytool. Just fill in the details, click Generate, and paste your customized keytool command into your terminal.
Ubuntu Generate Csr And Private Keys
If you prefer to roll your own keytool commands to generate your CSR, just follow our old instructions below:
Generate wep key through password. To generate a key based on a custom size, enter your size into either the custom size box, and its HEX or ASCII equivalent will be generated for you automatically in the result box.
Create a New Keystore
- You will be using the keytool command to create your new key-CSR pairing. Enter the following:
keytool -genkey -alias server -keyalg RSA -keysize 2048 -keystore yourdomain.jks
'Yourdomain' is the name of the domain you are securing. However, if you are ordering a Wildcard Certificate, do not include * in the beginning of the filename as this is not a valid filename character. - You will be prompted for the DN information. Please note: when it asks for first and last name, this is not YOUR first and last name, but rather your domain name and extension(i.e., www.yourdomain.com). If you are ordering a Wildcard Certificate this must begin with *. (example: *.digicert.com)
- Confirm that the information is correct by entering 'y' or 'yes' when prompted. Next you will be asked for your password to confirm. Make sure to remember the password you choose.
Generate Your CSR with Your New keystore
- Next, use keytool to actually create the Certificate Signing Request. Enter the following:
keytool -certreq -alias server -keyalg RSA -file yourdomain.csr -keystore yourdomain.jks
Again, 'yourdomain' is the name of the domain you are securing. (without the * character if you are ordering a Wildcard Certificate). - Enter the keystore password.
- Then the SSL Certificate CSR file is created. Open the CSR with a text editor, and copy and paste the text (including the BEGIN and END tags) into the DigiCert web order form.
- After you receive your SSL Certificate from DigiCert, you can install it.See SSL Certificate Installation :: Java Web Servers.
