Hi,
a customer needs a list of valid ciphersuites from a given allowed SSL_CTX_set_cipher_list.
The following command gets this list
michael@debdev ~ # openssl ciphers '!aNULL:ECDHE+AESGCM:ECDHE+AES' | tr ":" "\n" TLS_AES_256_GCM_SHA384 TLS_CHACHA20_POLY1305_SHA256 TLS_AES_128_GCM_SHA256 TLS_AES_128_CCM_SHA256 ECDHE-ECDSA-AES256-GCM-SHA384 ECDHE-RSA-AES256-GCM-SHA384 ECDHE-ECDSA-AES128-GCM-SHA256 ECDHE-RSA-AES128-GCM-SHA256 ECDHE-ECDSA-AES256-CCM8 ECDHE-ECDSA-AES256-CCM ECDHE-ECDSA-AES128-CCM8 ECDHE-ECDSA-AES128-CCM ECDHE-ECDSA-AES256-SHA384 ECDHE-RSA-AES256-SHA384 ECDHE-ECDSA-AES128-SHA256 ECDHE-RSA-AES128-SHA256 ECDHE-ECDSA-AES256-SHA ECDHE-RSA-AES256-SHA ECDHE-ECDSA-AES128-SHA ECDHE-RSA-AES128-SHA
