NAME

       SSL_CTX_use_serverinfo, SSL_CTX_use_serverinfo_file - use serverinfo extension

SYNOPSIS

        #include <openssl/ssl.h>

        int SSL_CTX_use_serverinfo(SSL_CTX *ctx, const unsigned char *serverinfo,
                                   size_t serverinfo_length);

        int SSL_CTX_use_serverinfo_file(SSL_CTX *ctx, const char *file);

DESCRIPTION

       These functions load "serverinfo" TLS ServerHello Extensions into the SSL_CTX.  A
       "serverinfo" extension is returned in response to an empty ClientHello Extension.

       SSL_CTX_use_serverinfo() loads one or more serverinfo extensions from a byte array into
       ctx.  The extensions must be concatenated into a sequence of bytes.  Each extension must
       consist of a 2-byte Extension Type, a 2-byte length, and then length bytes of
       extension_data.

       SSL_CTX_use_serverinfo_file() loads one or more serverinfo extensions from file into ctx.
       The extensions must be in PEM format.  Each extension must consist of a 2-byte Extension
       Type, a 2-byte length, and then length bytes of extension_data.  Each PEM extension name
       must begin with the phrase "BEGIN SERVERINFO FOR ".

NOTES
