.Ar keyword

.Ar tlsall ,

which allows the use of all supported TLS protocols and ciphers;

.Ar tlscompat ,

.Ar noverify ,

.Ar noname ,

.Ar muststaple ,

which requires the peer to provide a valid stapled OCSP response

with the handshake.

The following TLS options specify a value in the form of a key=value pair:

.Ar ciphers ,

which allows the supported TLS ciphers to be specified (see

.Xr tls_config_set_ciphers 3

for further details);

.Ar protocols ,

which allows the supported TLS protocols to be specified (see

.Xr tls_config_parse_protocols 3

for further details).

It is illegal to specify TLS options if not using TLS.
