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, 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 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.
NOTES
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.
RETURN VALUES
The 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
