## System diagnostics

This section provides information related to the system on which the application is running, including the application type, the Namirial Sign version, and the main installed software components.
The displayed data allows you to verify environment compatibility and identify any unsupported configurations.

The section also provides indications on the connectivity status to external services, allowing you to check their reachability from the network,
and reports information about the installed middleware required for web authentication.

## Device diagnostics

The device diagnostics displays the status of the signing devices available on the computer, such as smart cards and cryptographic tokens.
For each device, useful information is provided to verify correct recognition, the available certificates, and their validity.

This section is useful to ensure that the devices required for signing are correctly installed and ready for use.
In particular, for DigitalDNA devices, a **"Verify"** feature is available that allows you to check the Bluetooth and battery status.
Among the various details, it is important to monitor the PIN/PUK status to understand whether the device is locked.

## Certificate diagnostics

This section provides information about the status of certificates coming from devices, remote signing services, P12 files, or system certificates configured in the application.
All main certificate data is shown, such as the serial number and subject and issuer information.

It also provides useful information about certificate validity, highlighting whether a certificate is expired, suspended, revoked, or not usable for signing.
