view pre-shared-key in ASA config
show running won’t show you any pre-shared-keys for tunnels, aaa-server keys and failover keys in cleartext. You will only see things like:
failover key *****
aaa-server authserver (inside) host 192.168.1.1
key *****
tunnel-group clients ipsec-attributes
pre-shared-key *****
simply use the more system:running-config-command to show all your keys uncrypted.
