If your version of OpenSSL is old, unavailable ciphers will be discarded automatically. Always use the full ciphersuite above and let OpenSSL pick the ones it supports. | If your version of OpenSSL is old, unavailable ciphers will be discarded automatically.

Older versions of OpenSSL may not return the full list of algorithms. AES-GCM and some ECDHE are fairly recent, and not present on most versions of OpenSSL shipped with Ubuntu or RHEL. This listing below was obtained from a freshly built OpenSSL. | Older versions of OpenSSL may not return the full list of algorithms.
