SSL_library_init, OpenSSL_add_ssl_algorithms — initialize SSL library by registering algorithms

Synopsis

 #include <openssl/ssl.h>

 int SSL_library_init(void);

 int OpenSSL_add_ssl_algorithms(void);

Description

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

OpenSSL_add_ssl_algorithms() is a synonym for SSL_library_init() and is implemented as a macro.

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.
