A. show system setting ssl-decrypt certs
B. show system setting ssl-decrypt certificate

Answer

B. show system setting ssl-decrypt certificate

Explanation

This PAN-OS CLI command displays the details of the Forward Trust certificate, Forward Untrust certificate, and SSL Inbound Inspection certificate used for SSL Decryption on the Palo Alto Networks firewall.

The Forward Trust certificate is used to decrypt outbound SSL traffic, while the Forward Untrust certificate is used to re-encrypt decrypted traffic before forwarding it to the untrusted destination. The SSL Inbound Inspection certificate is used for inbound SSL traffic inspection.

By running this command, you can verify the validity, expiration dates, and other details of these certificates, which are crucial for proper SSL Decryption functionality. It helps troubleshoot issues related to expired or invalid certificates, which can cause SSL Decryption failures.
