A certificate authority will use a CSR to create your SSL certificate, but it does not need your private key. You need to keep your private key secret. The certificate created with a particular CSR will only work with the private key that was generated with it. So if you lose the private key, the certificate will no longer work. An SSL Certificate is a public key verified and signed by a Certificate Authority. You generate a public/private key pair, then from that generate a Certificate Signing Request (which includes the public key), which you send to the CA. It then signs that public key included in the CSR producing the certificate which it sends back to you. See also here.

Introduction

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.

Step 2: Create an RSA Private Key and CSR

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.

Step 5: Submit the CSR as Part of Your SSL Request

You can open the .csr file in a text editor to find the alphanumeric code that was generated. Bitdefender total security 2015 free license key generator free crack.

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. /des-key-generation-56-bits.html. 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.

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.

About SSL Certificates

SSL certificates are required in order to run web sites using the HTTPS protocol. For professional web sites, you usually buy such a certificate from Verisign, Thawte or any other ssl certificate vendor. SSL certificates use a chain of trust, where each certificate is signed (trusted) by a higher, more credible certificate. At the top of the chain of trust are the root certificates, owned by Verisign and others. These certificates are typically shipped with your operating system or web browser.

In Internet Explorer and Firefox

When you visit a web site over HTTPS, your web browser will receive the ssl certificate for the web site. It will examine the contents of the certificate to see that is indeed valid for the domain name you are trying to visit. After that, it will verify the chain of trust. It will look at who has signed the certificate. If that certificate is a root-certificate, it will compare it against the ones shipped with the operating system. If it is a non-root certificate, it will follow the chain of trust up one more level.

Self-signed certificates

When using a self-signed certificate, there is no chain of trust. The certificate has signed itself. The web browser will then issue a warning, telling you that the web site certificate cannot be verified. Therefore, you should not use self-signed certificates for professional use, as your visitors will not trust your web site to be safe.
