The list depends on settings like the cipher list, the supported protocol
versions, the security level, and the enabled signature algorithms.
SRP and PSK ciphers are only enabled if the appropriate callbacks or settings
have been applied.
This is the list that will be sent by the client to the server.
The list supported by the server might include more ciphers in case there is a
hole in the list of supported protocols.
The server will also not use ciphers from this list depending on the
configured certificates and DH parameters.
The list of ciphers that would be sent in a ClientHello can differ from
the list of ciphers that would be acceptable when acting as a server.
For example, additional ciphers may be usable by a server if there is
a gap in the list of supported protocols, and some ciphers may not be
usable by a server if there is not a suitable certificate configured.
If B<ssl> is NULL or no ciphers are available, NULL is returned.

SSL_get_shared_ciphers() creates a colon separated and NUL terminated list of
SSL_CIPHER names that are available in both the client and the server. B<buf> is
the buffer that should be populated with the list of names and B<size> is the
size of that buffer. A pointer to B<buf> is returned on success or NULL on
error. If the supplied buffer is not large enough to contain the complete list
of names then a truncated list of names will be returned. Note that just because
a ciphersuite is available (i.e. it is configured in the cipher list) and shared
by both the client and the server it does not mean that it is enabled (see the
description of SSL_get1_supported_ciphers() above). This function will return
available shared ciphersuites whether or not they are enabled. This is a server
side function only and must only be called after the completion of the initial
handshake.
