$ touch myserver.key $ chmod 600 myserver.key $ openssl req -new -config myserver.cnf -keyout myserver.key -out myserver.csr This will create a 2048-bit RSA key pair, store the private key in the file myserver.key and write the CSR to the file myserver.csr. The private key is stored with no passphrase. How to Generate a CSR for Apache Web Server Using OpenSSL The following instructions will guide you through the CSR generation process on Apache OpenSSL. To learn more about CSRs and the importance of your private key, reference our Overview of Certificate Signing Request article.

Introduction

Amazon Web Services: Create CSR and Install SSL Certificate (OpenSSL) Creating a CSR and installing your SSL certificate for Amazon Web Services (AWS) Use the instructions on this page to use OpenSSL to create your certificate signing request (CSR) and then upload and implement your SSL certificate in your AWS instance. Sep 11, 2018  The first thing to do would be to generate a 2048-bit RSA key pair locally. This pair will contain both your private and public key. You can use Java key tool or some other tool, but we will be working with OpenSSL. To generate a public and private key with a certificate signing request (CSR), run the following OpenSSL command. Mar 30, 2015  $ 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 fact. Sep 12, 2014 openssl req -key domain.key -new -out domain.csr. Answer the CSR information prompt to complete the process. The -key option specifies an existing private key (domain.key) that will be used to generate a new CSR. The -new option indicates that a CSR is being generated. Generate a CSR from an Existing Certificate and Private Key.

A Certificate Signing Request (CSR) is the first step in setting up an SSL Certificate on your website. SSL certificates are provided by Certificate Authorities (CA), which require a Certificate Signing Request (CSR).

This guide will instruct you on how to generate a Certificate Signing Request using OpenSSL.

• Access to a user account with root or sudo privileges
• A command line/terminal window
• If you’re working on a remote server, an established SSH connection to the server
• OpenSSL needs to be installed on your system to generate the key
• A text editor, such as nano, to view your key

Open a terminal window. Use your SSH connection to log into your remote server.

Note: If you are working locally, you don’t need an SSH connection. Also, most Linux systems will launch a terminal window by pressing Ctrl-Alt-T or Ctrl-Alt-F1.

It is advised to issue a new private key each time you generate a CSR. Hence, the steps below instruct on how to generate both the private key and the CSR.

Make sure to replace your_domain with the actual domain you’re generating a CSR for.

The commands are broken out as follows:

• openssl – activates the OpenSSL software
• req – indicates that we want a CSR
• –new –newkey – generate a new key
• rsa:2048 – generate a 2048-bit RSA mathematical key
• –nodes – no DES, meaning do not encrypt the private key in a PKCS#12 file
• –keyout – indicates the domain you’re generating a key for
• –out – specifies the name of the file your CSR will be saved as

Note: Use 2048-bit key pairs. The 4096-bit key pairs are more secure, however, they require a lot more server resources.

Your system should launch a text-based questionnaire for you to fill out.

Enter your information in the fields as follows:

• Country Name – use a 2-letter country code (US for the United States)
• State – the state in which the domain owner is incorporated
• Locality – the city in which the domain owner is incorporated
• Organization name – the legal entity that owns the domain
• Organizational unit name – the name of the department or group in your organization that deals with certificates
• Common name – typically the fully qualified domain name (FQDN), i.e. what the users type in a web browser to navigate to your website
• Email address – the webmaster’s email address
• Challenge password – an optional password for your key pair

Please take into account that Organization Name and Unit Name must not contain the following characters:

< > ~ ! @ # $ % ^ * / ( ) ?.,&

Once the software finishes, you should be able to find the CSR file in your working directory.

You can also enter the following:

The system should list out all certificate signing requests on the system. The one that matches the domain name you provided in Step 2 appended with the .csr extension is the one you need to look into.

You can open the .csr file in a text editor to find the alphanumeric code that was generated.

Enter the following command:

This text can be copied and pasted into a submittal form to request your SSL certificate from a Certificate Authority.

Make sure you copy the entire text. Some CAs may allow you to simply upload the .csr file you generated. Below is an example of a CSR.

You needn’t send the private key to the CA. Once you get your SSL certificate, the private key on the server will bind with it to encrypt communication.

Ubuntu add gpg key. Provided by:NAME gpg2 - OpenPGP encryption and signing toolSYNOPSIS gpg2 -homedir dir -options file options command argsDESCRIPTION gpg2 is the OpenPGP part of the GNU Privacy Guard (GnuPG). It is a tool to provide digitalencryption and signing services using the OpenPGP standard.

Now you know how to generate an OpenSSL certificate signing request. Before submitting the CSR to a certificate authority, we recommend verifying the information it holds. Use one of the widely available online CSR decoders.

SSL is a crucial protocol for securing traffic between a website and its visitors. It helps to protect sensitive information online, such as credit card data.

1. To create your CSR, see OpenSSL: How to Create Your CSR.

2. To install your SSL certificate, see AWS: How to Install Your SSL Certificate.

If you are looking for a simpler way to create CSRs and install and manage your SSL certificates, we recommend using the DigiCert^® Certificate Utility for Windows. You can use the DigiCert Utility to generate your CSR and install your SSL certificate. See Amazon Web Services: SSL Certificate CSR Creation.

I. OpenSSL: How to Create Your CSR

Use the instructions below for using OpenSSL to create your own shell commands for generating your Amazon Web Service (AWS) CSR.

Recommended: Save yourself some time. Use the DigiCert OpenSSL CSR Wizard to generate an OpenSSL command for creating your AWS CSR. Just fill in the form details, click Generate, and paste your customized OpenSSL command into your terminal.

If you prefer, you can build your own shell commands for generating your AWS CSR.

1. Use your terminal client (ssh) to log into your server/workstation.

2. At the prompt, enter the following command:

   Note: Make sure to replace Openssl Generate Cert From Csr And Keyboard

   1. Copy the Certificate File to Your Server/Workstation

      Download your Intermediate (DigiCertCA.crt) and Primary Certificate (your_domain_name.crt) files from your DigiCert account, then copy them to the directory on your server/workstation where you will keep your certificate and key files. Make them readable by root only.

   2. Upload Your SSL Certificate

      Next, you need to upload the certificate files (your_domain_com.key, your_domain_com.crt, and DigiCertCA.crt) to your AWS account.

   3. Implement Your SSL Certificate

      To implement your SSL certificate for your instance of AWS, consult the AWS Documentation.

      Note: Because all instances of Amazon Web Service (AWS) are unique, it is best to consult the Amazon documentation for instructions on how to install and configure your SSL certificate for you AWS instance.
