I need to provide a screenshot to show what kind of ciphers are supported on my openSSL server. Is there a command for this? or is this something i need to find elsewhere?
Is there a command for this?
openssl ciphers 'ALL'
will list all the encrypting ciphers.
openssl ciphers 'ALL:COMPLEMENTOFALL'
will list all ciphers.
If you want to confirm the list, you could use a script to cycle through each cipher and try to connect a tls-client with that cipher. You might also want to cycle over version as well, this is illustrated in this example bash script
