+You can test ciphers being used with the following
 <code>nmap --script ssl-enum-ciphers -p 443 1.2.3.4</code>
+===== Free Certificates with Lets Encrypt =====
+You can get free certificates for Palo Alto Networks devices using Lets Encrypt.
+Details are [[networking:ssl_certificate_lets_encrypt|here]].
 ===== Certificate Chains =====
 If you have a publicly signed certificate for GlobalProtect, make sure that the certificate file starts with server public certificate and then has the intermediate and lastly has the root certificate of the chain.
 ===== Secure SSL Ciphers =====
-When using SSL Certificate Profiles for managment interfaces, GlobalProtect Portals, etc, you can set the minimum TLS version. It is recommended to set TLS 1.2+.

 **Note**: PuTTY requires either the CBC or CRT ciphers. So, for PuTTY to work, you need at least once CBT or at least one CRT cipher
 This is for firewalls and Panorama management.

 After setting the cipher suite, you will need to run the following command. Or, you can type ''exit'' and then run the above command without the 'run' at the start.
