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.
If you prefer to roll your own keytool commands to generate your CSR, just follow our old instructions below:
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 new ssh key windows 10.
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.

How to generate a Certificate Signing Request for your Java Web Server
The following instructions will guide you through the CSR generation process on Microsoft IIS 8. To learn more about CSRs and the importance of your private key, reference our Overview of Certificate Signing Request article. If you already generated the CSR and received your trusted SSL certificate, reference our SSL Installation Instructions and disregard the steps below.
Click Start, Control Panel, System and Security, Administrative Tools, and then select Internet Information Services (IIS) Manager.
In the left Connections menu, select the server name (host) where you want to generate the request.
In the center menu, click the Server Certificates icon under the Security section near the bottom.
In the right Actions menu, click Create Certificate Request.
In the Distinguished Name Properties window, enter in the required CSR details and then click Next.
Note: To avoid common mistakes when filling out your CSR details, reference our Overview of Certificate Signing Request article.
In the Cryptographic Service Provider Properties window, select Microsoft RSA SChannel Cryptographic Provider and Bit Length of 2048, then click Next.
Note: Bit Length: 2048 is the current industry standard. You may choose a larger key size, but only if you have a requirement to do so, as longer key lengths increase latency and may reduce compatibility.
Click Browse /generate-diffie-hellman-key-ubuntu.html. to specify the location where you want to save the CSR as a “.txt” file and click Finish.
Locate and open the newly created CSR from the specified location you choose in a text editor such as Notepad and copy all the text including:
Return to the Generation Form on our website and paste the entire CSR into the blank text box and continue with completing the generation process.
Upon generating your CSR, your order will enter the validation process with the issuing Certificate Authority (CA) and require the certificate requester to complete some form of validation depending on the certificate purchased. For information regarding the different levels of the validation process and how to satisfy the industry requirements, reference our validation articles.
After you complete the validation process and receive the trusted SSL Certificate from the issuing Certificate Authority (CA), proceed with the next step using our SSL Installation Instructions for Microsoft IIS 8.
