NAME

SSL_library_init, OpenSSL_add_ssl_algorithms, - initialize SSL library by registering algorithms

SYNOPSIS

#include <openssl/ssl.h>

int SSL_library_init(void);
#define OpenSSL_add_ssl_algorithms()    SSL_library_init()

DESCRIPTION

SSL_library_init() registers the available SSL/TLS ciphers and digests.

OpenSSL_add_ssl_algorithms() is a synonym for SSL_library_init().

NOTES

SSL_library_init() must be called before any other action takes place. SSL_library_init() is not reentrant.

WARNING

SSL_library_init() adds ciphers and digests used directly and indirectly by SSL/TLS.

RETURN VALUES

SSL_library_init() always returns "1", so it is safe to discard the return value.

HISTORY

The SSL_library_init() and OpenSSL_add_ssl_algorithms() functions were deprecated in OpenSSL 1.1.0 by OPENSSL_init_ssl().
