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, SSL_METHOD *method); 
int
SSL_set_ssl_method(SSL *s, SSL_METHOD *method);
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.
