NAME

SSL_SESSION_get0_id_context, SSL_SESSION_set1_id_context - get and set the SSL ID context associated with a session

SYNOPSIS

 #include <openssl/ssl.h>

 const unsigned char *SSL_SESSION_get0_id_context(const SSL_SESSION *s,
                                                  unsigned int *len);
 int SSL_SESSION_set1_id_context(SSL_SESSION *s, const unsigned char *sid_ctx,
                                unsigned int sid_ctx_len);

DESCRIPTION

See SSL_CTX_set_session_id_context(3) for further details on session ID contexts.

SSL_SESSION_get0_id_context() returns the ID context associated with the SSL/TLS session s. The length of the ID context is written to *len if len is not NULL.

The value returned is a pointer to an object maintained within s and should not be released.

SSL_SESSION_set1_id_context() takes a copy of the provided ID context given in sid_ctx and associates it with the session s. The length of the ID context is given by sid_ctx_len which must not exceed SSL_MAX_SID_CTX_LENGTH bytes.

RETURN VALUES

SSL_SESSION_set1_id_context() returns 1 on success or 0 on error.

HISTORY

The SSL_SESSION_get0_id_context() function was added in OpenSSL 1.1.0.
