PAN-OS 9.1 Decryption Cipher Suites

List of cipher suites supported for IPSec on firewalls running PAN-OS® 9.1 in normal operation mode.
The following table lists cipher suites for decryption that are supported on firewalls running a PAN-OS® 9.1 release in normal (non-FIPS-CC) operational mode.
If your firewall is running in FIPS-CC mode, see the list of PAN-OS 9.1 Cipher Suites Supported in FIPS-CC Mode.
