thanks Matt. I couldnt find the -stdname option on my macOS openssl, but using ur example above, i could find the ones they map to. So I am good and thanks very much for your kind help.
Bonus question :-) I have a 2 more TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256 and TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256
I dont even find these listed on the man pages - https://www.openssl.org/docs/man1.0.2/man1/ciphers.html and hence was curious
thanks

In the openssl libs that i have installed on ubuntu/rhel/mac-os, i dont find the following ciphers when i run 'openssl ciphers' commandTLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256Is there a specific version to install to get these OR how to manually build openssl so that these above ciphers are available
thanks
Mario
