+## About cipher suite and algorithm configuration
+
+{% data variables.product.prodname_ghe_server %} allows you to configure which cipher suites and cryptographic algorithms to use for:
+
+* **TLS connections** on ports 443 (HTTPS web interface) and 8443 (HTTPS management console)
+* **SSH connections** on port 22 (Git operations via SSH) and port 122 (administrative shell access)
+
+The default secure cipher suites are based on industry-standard TLS hardening recommendations and modern security best practices. Most organizations should use these defaults unless specific compliance or security requirements dictate otherwise.
+
+Organizations may need to customize cipher suites and cryptographic algorithms to meet specific organizational security policies, industry standards, or regulatory requirements.
+
+Starting in {% data variables.product.prodname_ghe_server %} 3.19, TLS ciphers are configurable and the web gateway uses more secure cipher defaults. To maintain backwards compatibility with existing instances, newly provisioned instances will use these new defaults.
+
+> [!WARNING]
+> Configuring overly restrictive cipher suites may prevent clients from connecting to your instance. Always test changes in a non-production environment first, ensure at least one cipher suite is compatible with your clients, and verify connectivity after applying configuration changes.
+
+> [!NOTE]
+> When configuring TLS cipher suites, use comma-separated values in your configuration commands. {% data variables.product.prodname_ghe_server %} automatically converts comma delimiters to colons for the HAProxy configuration. Cipher suites are evaluated in the order specified, so list your preferred ciphers first.
+
+## Configuring TLS cipher suites
+
+You can configure the cipher suites used for TLS 1.2 and TLS 1.3 connections.
+
+### Listing available TLS cipher suites
+
+{% data reusables.enterprise_installation.ssh-into-target-instance %}
+
+1. To view the default secure cipher suites for TLS 1.2, run the following command.
+
+   ```shell copy
+   ghe-crypto list tlsv12-ciphersuites
+   ```
+
+1. To view the default secure cipher suites for TLS 1.3, run the following command.
+
+   ```shell copy
+   ghe-crypto list tlsv13-ciphersuites

+1. Temporarily restore the default settings to verify the issue is cipher-related. For more information, see [Restoring default cipher suite and algorithm settings](#restoring-default-cipher-suite-and-algorithm-settings).
+1. If the issue persists after restoring defaults, contact {% data variables.contact.contact_ent_support %}.
+
+## Restoring default cipher suite and algorithm settings
+
+To restore the default secure cipher suites or algorithms, unset the configuration value.
+
+{% data reusables.enterprise_installation.ssh-into-target-instance %}
+
+1. Unset the configuration setting. Replace `SETTING` with the name of the setting you want to restore to defaults.
+
+   ```shell copy

+
+   For example, to restore default TLS 1.2 cipher suites:

+   ```
+
+{% data reusables.enterprise.apply-configuration %}

-
-   ```shell copy
-   ghe-crypto list ssh-ciphers
-   ```
-
-1. To view the default secure SSH MAC algorithms, run the following command.
-
-   ```shell copy

-
-### Troubleshooting cipher configuration
-
-If clients cannot connect to {% data variables.location.product_location %} after changing cipher configuration, you can troubleshoot the issue.
-
-1. Check that your clients support the configured TLS or SSH protocol versions.
-1. Verify that at least one configured cipher suite is compatible with your clients.
-1. Review the instance logs for TLS handshake failures or SSH connection errors. For more information about accessing logs, see [AUTOTITLE](/admin/monitoring-and-managing-your-instance/monitoring-your-instance/about-system-logs).
-1. Temporarily restore the default settings to verify the issue is cipher-related. For more information, see [Restoring default cipher suite and algorithm settings](#restoring-default-cipher-suite-and-algorithm-settings).
-1. If the issue persists after restoring defaults, contact {% data variables.contact.contact_ent_support %}.
-
-### Restoring default cipher suite and algorithm settings
-
-To restore the default secure cipher suites or algorithms, unset the configuration value.
-
-{% data reusables.enterprise_installation.ssh-into-target-instance %}
-
-1. Unset the configuration setting. Replace `SETTING` with the name of the setting you want to restore to defaults.
-
-   ```shell copy
-   ghe-config --unset github-ssl.SETTING
-   ```
-
-   For example, to restore default TLS 1.2 cipher suites:
-
-   ```shell
-   ghe-config --unset github-ssl.tlsv12-ciphersuites
-   ```
-
-{% data reusables.enterprise.apply-configuration %}
-
-1. If you configured a user message or maintenance mode, remove the message and disable maintenance mode.
+You can configure the cipher suites and cryptographic algorithms that {% data variables.product.prodname_ghe_server %} uses for TLS and SSH connections. For more information, see [AUTOTITLE](/admin/configuring-settings/hardening-security-for-your-enterprise/configuring-tls-and-ssh-ciphers).
