| =head1 NAME |
| |
| 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)> are not affected, except when |
| L<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)>. |
| |
| When L<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. |
| |
| =head1 RETURN VALUES |
| |
| The following return values can occur for SSL_CTX_set_ssl_version() |
| and SSL_set_ssl_method(): |
| |
| =over 4 |
| |
| =item Z<>0 |
| |
| The new choice failed, check the error stack to find out the reason. |
| |
| =item Z<>1 |
| |
| The operation succeeded. |
