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(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.
