# 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 are not affected, except when SSL_clear 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.

When SSL_clear 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():

1. The new choice failed, check the error stack to find out the reason.

2. The operation succeeded.
