OpenSSL SSL_library_init(3openssl) 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(). ATTRIBUTES See attributes(7) for descriptions of the following attributes: +---------------+--------------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+--------------------------+ |Availability | library/security/openssl | +---------------+--------------------------+ |Stability | Pass-through uncommitted | +---------------+--------------------------+ NOTES SSL_library_init() must be called before any other action takes place. SSL_library_init() is not reentrant. Source code for open source software components in Oracle Solaris can be found at https://www.oracle.com/downloads/opensource/solaris-source- code-downloads.html. 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. Further information about this software can be found on the open source community website at https://www.openssl.org/. 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.
