SSL_CTX_SET_SSL_VERSION(3) FreeBSD Library Functions Manual NAME SSL_CTX_set_ssl_version, SSL_set_ssl_method, SSL_CTX_get_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_CTX_get_ssl_method(SSL_CTX *ctx); 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 called. SSL_set_ssl_method() sets a new TLS/SSL method for a particular SSL object s. It may be reset when SSL_clear(3) is called. SSL_CTX_get_ssl_method() and SSL_get_ssl_method() return a function pointer to the TLS/SSL method set in ctx and ssl, respectively. 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.
