NAME

SSL_CTX_set_ssl_version, SSL_set_ssl_method, SSL_get_ssl_methodchoose a new TLS/SSL method

SYNOPSIS

#include <openssl/ssl.h>
int
SSL_CTX_set_ssl_version(SSL_CTX *ctx, const SSL_METHOD *method);
int
SSL_set_ssl_method(SSL *s, const SSL_METHOD *method);
const SSL_METHOD *
SSL_get_ssl_method(SSL *ssl);

DESCRIPTION

SSL_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 called.
SSL_set_ssl_method() sets a new TLS/SSL method for a particular SSL object s. It may be reset when SSL_clear(3) is called.
SSL_get_ssl_method() returns a function pointer to the TLS/SSL method set in ssl.
The 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.
