SSL_CTX_set_ssl_version, SSL_set_ssl_method, SSL_get_ssl_method
|
- choose a new TLS/SSL method
|
|
=head1 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);
|
|
=head1 DESCRIPTION
|
|
SSL_CTX_set_ssl_version() sets a new default TLS/SSL B<method> for SSL objects
|
newly created from this B<ctx>. SSL objects already created with
|
L<SSL_new(3)|SSL_new(3)> are not affected, except when
|
L<SSL_clear(3)|SSL_clear(3)> is being called.
|
|
SSL_set_ssl_method() sets a new TLS/SSL B<method> for a particular B<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 B<ssl>.
|
|
=head1 NOTES
|
|
The available B<method> choices are described in
|
L<SSL_CTX_new(3)|SSL_CTX_new(3)>.
|
|
When L<SSL_clear(3)|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.
|
|
