NAME

SSL_SESSION_get_id, SSL_SESSION_set1_id - get and set the SSL session ID

SYNOPSIS

 #include <openssl/ssl.h>
 const unsigned char *SSL_SESSION_get_id(const SSL_SESSION *s,
                                         unsigned int *len);
 int SSL_SESSION_set1_id(SSL_SESSION *s, const unsigned char *sid,
                         unsigned int sid_len);

DESCRIPTION

SSL_SESSION_get_id() returns a pointer to the internal session id value for the session s. The length of the id in bytes is stored in *len. The length may be 0. The caller should not free the returned pointer directly.

SSL_SESSION_set1_id() sets the session ID for the ssl SSL/TLS session to sid of length sid_len.

RETURN VALUES

SSL_SESSION_get_id() returns a pointer to the session id value. SSL_SESSION_set1_id() returns 1 for success and 0 for failure, for example if the supplied session ID length exceeds SSL_MAX_SSL_SESSION_ID_LENGTH.
