=head1 NAME
|
|
|
|
SSL_library_init, OpenSSL_add_ssl_algorithms, SSLeay_add_ssl_algorithms
|
|
- initialize SSL library by registering algorithms
|
|
|
|
=head1 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()
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
SSL_library_init() registers the available ciphers and digests.
|
|
|
|
OpenSSL_add_ssl_algorithms() and SSLeay_add_ssl_algorithms() are synonyms
|
|
for SSL_library_init().
|
|
|
|
=head1 NOTES
|
|
|
|
SSL_library_init() must be called before any other action takes place.
|
|
|
|
=head1 WARNING
|
|
|
|
SSL_library_init() only registers ciphers. Another important initialization
|
|
is the seeding of the PRNG (Pseudo Random Number Generator), which has to
|
|
be performed separately.
|
|
|
|
=head1 EXAMPLES
|
|
|
|
A typical TLS/SSL application will start with the library initialization,
|
|
will provide readable error messages and will seed the PRNG.
|
|
|
|
SSL_load_error_strings(); /* readable error messages */
|
|
SSL_library_init(); /* initialize library */
|
|
actions_to_seed_PRNG();
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
SSL_library_init() always returns "1", so it is safe to discard the return
|
|
value.
