=head1 DESCRIPTION
|
|
|
|
Several OpenSSL structures can have application specific data attached to them.
|
|
These functions are used internally by OpenSSL to manipulate application
|
|
specific data attached to a specific structure.
|
|
|
|
SSL_SESSION_get_ex_new_index() is used to register a new index for application
|
|
specific data.
|
|
|
|
SSL_SESSION_set_ex_data() is used to store application data at B<arg> for B<idx>
|
|
into the B<session> object.
|
|
|
|
SSL_SESSION_get_ex_data() is used to retrieve the information for B<idx> from
|
|
B<session>.
|
|
|
|
A detailed description for the B<*_get_ex_new_index()> functionality
|
|
can be found in L<RSA_get_ex_new_index(3)|RSA_get_ex_new_index(3)>.
|
|
The B<*_get_ex_data()> and B<*_set_ex_data()> functionality is described in
|
|
L<CRYPTO_set_ex_data(3)|CRYPTO_set_ex_data(3)>.
|
|
|
|
=head1 WARNINGS
|
|
|
|
The application data is only maintained for sessions held in memory. The
|
|
application data is not included when dumping the session with
|
|
i2d_SSL_SESSION() (and all functions indirectly calling the dump functions
|
|
like PEM_write_SSL_SESSION() and PEM_write_bio_SSL_SESSION()) and can
|
|
therefore not be restored.
