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 B. 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 B into B. 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 ". =head1 NOTES =head1 RETURN VALUES On success, the functions return 1. On failure, the functions return 0.
