=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 SSL/TLS 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. |
|
SSL_library_init() is not reentrant. |
|
|
|
=head1 WARNING |
|
|
|
SSL_library_init() adds ciphers and digests used directly and indirectly by |
|
SSL/TLS. |
|
|
|
=head1 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 */ |
|
|
|
=head1 RETURN VALUES |
|
|
|
SSL_library_init() always returns "1", so it is safe to discard the return |
|
value. |
|
|
|
=head1 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. |
