# How to display a remote SSL certificate details using CLI tools?

You can use various command-line tools to display details of a remote SSL certificate. One common tool is `openssl`, which provides commands to fetch and examine SSL certificates.

Here's an example of how to use `openssl s_client` to view SSL certificate details of a remote server:

```bash
openssl s_client -connect example.com:443

```

Replace `example.com` with the domain name or IP address of the remote server you want to examine. This command initiates an SSL connection to the specified server and prints out the certificate details.

If you only want to see the certificate details without initiating an SSL connection, you can use the following:

```bash
echo | openssl s_client -showcerts -connect example.com:443 2>/dev/null | openssl x509 -text

```

This command will fetch the SSL certificate from the remote server and display its details.

Another method involves using the `gnutls-cli` tool:

```bash
gnutls-cli --print-cert example.com

```

Replace `example.com` with the domain name or IP address you wish to check.

Additionally, the `curl` command can be used to fetch and display the SSL certificate details:

```bash
curl -v <https://example.com>

```

This will display verbose output that includes SSL certificate information.

Remember to replace `example.com` with the actual domain you want to examine. These tools can provide detailed information about the SSL certificate, such as the certificate chain, expiration date, issuer information, and more.
