SSL_CTX_set_ssl_version, SSL_set_ssl_method, SSL_get_ssl_method - choose a new TLS/SSL method
Synopsis #include <openssl/ssl.h> int
SSL_CTX_set_ssl_version(SSL_CTX *ctx, SSL_METHOD *method); int
SSL_set_ssl_method(SSL *s, SSL_METHOD *method); SSL_METHOD
*SSL_get_ssl_method(SSL *ssl);
DESCRIPTIONSSL_CTX_set_ssl_version() sets a new default TLS/SSL method
for SSL objects newly created from this ctx. SSL objects already
created with SSL_new(3) are not affected, except
when SSL_clear(3) is
being called.
SSL_set_ssl_method() sets a new TLS/SSL method for a particular
ssl object. It may be reset, when SSL_clear() is called.
SSL_get_ssl_method() returns a function pointer to the TLS/SSL
method set in ssl.
NOTESThe available method choices are described in SSL_CTX_new(3) .
When SSL_clear(3) is called and no session
is connected to an SSL object, the method of the SSL object is reset
to the method currently set in the corresponding SSL_CTX object.
RETURN VALUESThe following return values can occur for SSL_CTX_set_ssl_version()
and SSL_set_ssl_method():
0 The new choice failed, check the error stack to find out the
reason.
1 The operation succeeded.
