What do you need to know about OpenSSL command line tool?

OpenSSL is an open-source command line tool that is commonly used to generate private keys, create CSRs, install your SSL/TLS certificate, and identify certificate information. We designed this quick reference guide to help you understand the most common OpenSSL commands and how to use them. This guide is not meant to be comprehensive.

How to check for public key in OpenSSL?

Use the following command to view the contents of your certificate: openssl x509 -text -in yourdomain.crt -noout. Verifying Your Keys Match. To verify the public and private keys match, extract the public key from each file and generate a hash output for it. All three files should share the same public key and the same hash value.

What do I need to create SSL certificate with OpenSSL?

OpenSSL and CSR Creation The first step to obtaining an SSL certificate is using OpenSSL to create a certificate signing request (CSR) that can be sent to a Certificate Authority (CA) (e.g., DigiCert). The CSR contains the common name (s) you want your certificate to secure, information about your company, and your public key.

What should I do if my OpenSSL certificate does not match?

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. Check an MD5 hash of the public key to ensure that it matches with what is in a CSR or private key
