One of the most versatile SSL tools is OpenSSL which is an open source implementation of the SSL protocol. There are versions of OpenSSL for nearly every platform, including Windows, Linux, and Mac OS X. OpenSSL is commonly used to create the CSR and private key for many different platforms, including Apache. However, it also has hundreds of different functions that allow you to view the details of a CSR or certificate, compare an MD5 hash of the certificate and private key (to make sure they match), verify that a certificate is installed properly on any website, and convert the certificate to a different format. A compiled version of OpenSSL for Windows can be found here.

If you don't want to bother with OpenSSL, you can do many of the same things with our SSL Certificate Tools. Below, we have listed the most common OpenSSL commands and their usage:

1. If you are using Dynamic DNS, your CN should have a wild-card, for example:.api.com. Otherwise, use the hostname or IP address set in your Gateway Cluster (for example. 192.16.183.131 or dp1.acme.com). Run the following OpenSSL command to generate your private key and public certificate. Answer the questions and enter the Common Name when.
2. Jul 07, 2016  openssl req –new –newkey rsa:2048 –nodes –keyout server.key –out server.csr Now, you will have two files private key files and CSR (certificate signing request). You will be asked to provide Common Name where you have to add FQDN (e.g. – example.com).

Reasons for importing keys include wanting to make a backup of a private key (generated keys are non-exportable, for security reasons), or if the private key is provided by an external source.

General OpenSSL Commands

These commands allow you to generate CSRs, Certificates, Private Keys and do other miscellaneous tasks.

• Generate a new private key and Certificate Signing Request
• Generate a self-signed certificate (see How to Create and Install an Apache Self Signed Certificate for more info)
• Generate a certificate signing request (CSR) for an existing private key
• Generate a certificate signing request based on an existing certificate
• Remove a passphrase from a private key

Checking Using OpenSSL

If you need to check the information within a Certificate, CSR or Private Key, use these commands. You can also check CSRs and check certificates using our online tools.

• Check a Certificate Signing Request (CSR)
• Check a private key
• Check a certificate
• Check a PKCS#12 file (.pfx or .p12)

Debugging Using OpenSSL

If you are receiving an error that the private doesn't match the certificate or that a certificate that you installed to a site is not trusted, try one of these commands. If you are trying to verify that an SSL certificate is installed correctly, be sure to check out the SSL Checker.

• Check an MD5 hash of the public key to ensure that it matches with what is in a CSR or private key
• Check an SSL connection. All the certificates (including Intermediates) should be displayed

Converting Using OpenSSL

These commands allow you to convert certificates and keys to different formats to make them compatible with specific types of servers or software. For example, you can convert a normal PEM file that would work with Apache to a PFX (PKCS#12) file and use it with Tomcat or IIS. Use our SSL Converter to convert certificates without messing with OpenSSL.

• Convert a DER file (.crt .cer .der) to PEM
• Convert a PEM file to DER
• Convert a PKCS#12 file (.pfx .p12) containing a private key and certificates to PEM

  You can add -nocerts to only output the private key or add -nokeys to only output the certificates.

• Convert a PEM certificate file and a private key to PKCS#12 (.pfx .p12)

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.

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.
