SSL_SESSION_get_protocol_version, SSL_SESSION_set_protocol_version - get and set the session protocol version


 #include <openssl/ssl.h>

 int SSL_SESSION_get_protocol_version(const SSL_SESSION *s);
 int SSL_SESSION_set_protocol_version(SSL_SESSION *s, int version);


SSL_SESSION_get_protocol_version() returns the protocol version number used by session s.

SSL_SESSION_set_protocol_version() sets the protocol version associated with the SSL_SESSION object s to the value version. This value should be a version constant such as TLS1_3_VERSION etc. For example, this could be used to set up a session based PSK (see SSL_CTX_set_psk_use_session_callback(3)).


SSL_SESSION_get_protocol_version() returns a number indicating the protocol version used for the session; this number matches the constants e.g. TLS1_VERSION, TLS1_2_VERSION or TLS1_3_VERSION.

Note that the SSL_SESSION_get_protocol_version() function does not perform a null check on the provided session s pointer.

SSL_SESSION_set_protocol_version() returns 1 on success or 0 on failure.

The SSL_SESSION_get_protocol_version() function was added in OpenSSL 1.1.0. The SSL_SESSION_set_protocol_version() function was added in OpenSSL 1.1.1.
