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 ''.
