6- initialize SSL library by registering algorithms
7
8=head1 SYNOPSIS
9
10 #include <openssl/ssl.h>
11
12 int SSL_library_init(void);
13 #define OpenSSL_add_ssl_algorithms()    SSL_library_init()
14 #define SSLeay_add_ssl_algorithms()     SSL_library_init()
15
16=head1 DESCRIPTION
17
18SSL_library_init() registers the available ciphers and digests.
19
20OpenSSL_add_ssl_algorithms() and SSLeay_add_ssl_algorithms() are synonyms
21for SSL_library_init().
22
23=head1 NOTES
24
25SSL_library_init() must be called before any other action takes place.
26
27=head1 WARNING
28
29SSL_library_init() only registers ciphers. Another important initialization
30is the seeding of the PRNG (Pseudo Random Number Generator), which has to
31be performed separately.
32
33=head1 EXAMPLES
34
35A typical TLS/SSL application will start with the library initialization,
36will provide readable error messages and will seed the PRNG.
37
38 SSL_load_error_strings();                /* readable error messages */
39 SSL_library_init();                      /* initialize library */
40 actions_to_seed_PRNG(); 
41
42=head1 RETURN VALUES
43
44SSL_library_init() always returns "1", so it is safe to discard the return
45value.
