NAME
SSL_library_init, OpenSSL_add_ssl_algorithms, SSLeay_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()
#define SSLeay_add_ssl_algorithms() SSL_library_init()
DESCRIPTION
SSL_library_init() registers the available SSL/TLS ciphers and digests.
OpenSSL_add_ssl_algorithms() and SSLeay_add_ssl_algorithms() are
synonyms for SSL_library_init().

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

This software was built from source available at
https://github.com/oracle/solaris-userland. The original community
source was downloaded from
https://www.openssl.org/source/openssl-1.0.2ze.tar.gz.

WARNING
SSL_library_init() adds ciphers and digests used directly and
indirectly by SSL/TLS.
EXAMPLES
A typical TLS/SSL application will start with the library
initialization, and provide readable error messages.
SSL_load_error_strings(); /* readable error messages */
SSL_library_init(); /* initialize library */
RETURN VALUES
SSL_library_init() always returns "1", so it is safe to discard the
return value.
NOTES
OpenSSL 0.9.8o and 1.0.0a and later added SHA2 algorithms to
SSL_library_init(). Applications which need to use SHA2 in earlier
versions of OpenSSL should call OpenSSL_add_all_algorithms() as well.
