+  This setting is only available when support for OpenSSL was built in. It sets
+  the default string describing the list of signature algorithms related to
+  client authentication for all "server" lines which do not explicitly define
+  theirs. The format of the string is a colon-delimited list of signature
+  algorithms. Each signature algorithm can use one of two forms: TLS1.3 signature
+  scheme names ("rsa_pss_rsae_sha256") or the public key algorithm + digest form
+  ("ECDSA+SHA256"). A list can contain both forms. For more information on the
+  format, see SSL_CTX_set1_client_sigalgs(3). A list of signature algorithms is
+  also available in RFC8446 section 4.2.3 and in OpenSSL in the ssl/t1_lib.c
