1=pod 2 3=head1 NAME 4 5SSL_SESSION_get0_id_context, 6SSL_SESSION_set1_id_context 7- get and set the SSL ID context associated with a session 8 9=head1 SYNOPSIS 10 11 #include <openssl/ssl.h> 12 13 const unsigned char *SSL_SESSION_get0_id_context(const SSL_SESSION *s, 14 unsigned int *len); 15 int SSL_SESSION_set1_id_context(SSL_SESSION *s, const unsigned char *sid_ctx, 16 unsigned int sid_ctx_len); 17 18=head1 DESCRIPTION 19 20See L<SSL_CTX_set_session_id_context(3)> for further details on session ID 21contexts. 22 23SSL_SESSION_get0_id_context() returns the ID context associated with 24the SSL/TLS session B<s>. The length of the ID context is written to 25B<*len> if B<len> is not NULL. 26 27The value returned is a pointer to an object maintained within B<s> and 28should not be released. 29 30SSL_SESSION_set1_id_context() takes a copy of the provided ID context given in 31B<sid_ctx> and associates it with the session B<s>. The length of the ID context 32is given by B<sid_ctx_len> which must not exceed SSL_MAX_SID_CTX_LENGTH bytes. 33 34=head1 RETURN VALUES 35 36SSL_SESSION_set1_id_context() returns 1 on success or 0 on error. 37 38=head1 SEE ALSO 39 40L<ssl(7)>, 41L<SSL_set_session_id_context(3)> 42 43=head1 HISTORY 44 45The SSL_SESSION_get0_id_context() function was added in OpenSSL 1.1.0. 46 47=head1 COPYRIGHT 48 49Copyright 2015-2020 The OpenSSL Project Authors.
