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:

I'm using openssl on Mac OS X 10.9 to generate a self-signed certificate for Windows Server Remote Desktop Services. How to add extended key usage string when generating a self-signed certificate using openssl. If you are just generating a CSR with this command line then use -reqexts 'my server exts' to request that the CA later generate. Sep 11, 2018 How to generate a certificate signing request solely depends on the platform you’re using and the particular tool of choice. We will be generating a CSR using OpenSSL. OpenSSL is a widely-used tool for working with CSR files and SSL certificates and is available for download on the official OpenSSL website. Mar 30, 2015  You can do this with these steps: 1. Type the following command in an open terminal window on your computer to display the list of curves supported by your version of OpenSSL. Once you have selected a curve, then you can use the following command to create the private key file. $ 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.

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

Openssl Generate Csr San

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. Sql server uniqueidentifier primary key auto generated.

• 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)
