The "Certificates (eZLA)" functionality from the "Staff" menu is used to import certificates that provide medical staff with an access to the eZLA platform dedicated to issuing electronic sick leave to the jHIS system. After selecting this functionality, a list of certificates of the logged staff appears and at each of them the “Download”, "Edit" and "Remove" buttons, and under the list of certificates, the "Add" button is displayed.

To add a new certificate, click "Add". Then a form for adding a certificate will be displayed, in which the certificate file (previously downloaded from the PUE ZUS platform or P1 platform), password for the file should be indicated and indicate whether the certificate is active (active certificate will be used for communication with the eZLA platform of ZUS; only one certificate can be active; checking the certificate as active will automatically mark other certificates as inactive). After entering the data, save it by clicking "Add".

To modify the certificate data, click the "Edit" button next to the appropriate certificate in the list of certificates. The certificate data form will then be displayed, where you can specify a different certificate file (or check the box "Leave certificate file unchanged" if changes do not apply to the certificate file), indicate a new password (or check the box "leave password unchanged" if changes do not apply to the password), select whether the certificate should be active. After making changes, save them by clicking the "Save" button.

To delete a certificate, click the "Remove" button next to the appropriate certificate in the list of certificates. A window will then be displayed asking you to confirm that you want to delete the certificate. After confirmation, the certificate will be deleted.

To get the certificate and save it to disk, click the "Download" button next to certificate on the list of certificates. The window with information about the location on the disk, where the saved file with the certificate should be saved, should be revealed.
