    • This guide will show you how to read the SSL Certificate Information from a text-file on your server or from a remote server by connecting to it with the OpenSSL client.

    Read the SSL Certificate information from a text-file at the CLI

    If you have your certificate file available to you on the server, you can read the contents with the client tools.

    By default, your certificate will look like this.

    $ cat certificate.crt -----BEGIN CERTIFICATE----- MIIEzTCCA7WgAwIBAgISESHAjlbjcoBHxBYXS12oY6VjMA0GCSqGSIb3DQEBCwUA ...

    CzgXBhDR3themzPx4jwx2ckNFpNDK/6yQgrKaHTewAAj -----END CERTIFICATE-----

    Which doesn’t really tell you much.

    $ openssl x509 -text -noout -in certificate.crt Certificate: ...
