NAME
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(const 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 reason.
- 1
-
The operation succeeded.
