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

SSL_SESSION_get0_id_context() returns the ID context associated with s. The length of the ID context in bytes is written to *len if len is not NULL.

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_get0_id_context() returns an internal pointer to an object maintained within s that should not be freed by the caller.

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