If you want to know a little bit about a X.509 certificate CertTool has you covered. Just select a file in PEM or DER format that contains the certificate and it will show you some details. And if you just want to share the certificate to the app, you can do that as well.

Envoh helps you monitor environments, servers, and SSL/TLS certificates from one app. Organize servers by environment, track health signals, and receive alerts when attention is needed. Built for developers, small teams, and technical users, Envoh brings server availability and certificate expiration monitoring together. ENVIRONMENTS AND SERVERS Group servers into environments such as production, staging, or development. View health summaries by status and open each server to see which monitoring signals need attention. - Organize servers by environment - View counts of critical, warning, unknown, and healthy servers - Filter environments by type and servers by health status - Follow health updates without manually refreshing the screen SERVER CHECK Check an HTTP or HTTPS endpoint to monitor your service's availability. - Configure the endpoint and request settings - Set normal and error check intervals within your plan limits - Choose how many failures trigger a notification - Review the latest check result HEARTBEAT Let your servers, scripts, or containers report that they are running by sending Heartbeats to Envoh. - View the latest received Heartbeat - Enable absence detection and configure the timeout - Receive notifications when configured Heartbeats stop arriving - Monitor workloads that send outbound requests without exposing a public health endpoint Heartbeat monitoring requires you to configure your server or workload to send requests to Envoh. SSL/TLS CERTIFICATES Track certificate health and expiration dates across your domains. - Monitor SSL/TLS certificates - Receive alerts before certificates expire - Sort certificates by expiration date or name - Filter the list to show your certificates, shared certificates, or both SHARING Give other users read-only access through Share Keys. - Share selected certificates or an entire environment - Follow servers and health updates in shared environments - Claim keys provided by other users - Close or reopen keys to control new claims - Revoke individual access or delete a key to remove access granted through it Closing a key prevents new claims but preserves existing access. Sharing an environment includes its linked server data and monitoring settings. Share only with people authorized to view that information. PLANS AND SUBSCRIPTIONS The free plan includes all monitoring and sharing features, with limits suited to a smaller set of environments, servers, and certificates. Paid plans increase capacity and allow shorter monitoring intervals. Terms of Use: https://envoh.app/web/terms Privacy Policy: https://envoh.app/web/privacy
