+Set/Get private data
+~~~~~~~~~~~~~~~~~~~~
+For session-based operations, the set and get API provides a mechanism for an
+application to store and retrieve the private data information stored along
with
+the rte_cryptodev_sym_session session.
+
+For example, suppose an application is submitting a rte_cryptodev_sym_session
+operation and wants to indicate private data information is required to be used
wants to indicate private data information which is required
+after completion of the rte_cryptodev_sym_session operation. In this case, the
+application can use the set API to set the private data and retrieve it using
get API.
+
+.. code-block:: c
+
+ int rte_cryptodev_sym_session_set_private_data(
+ struct rte_cryptodev_sym_session *sess, void *data, uint16_t
size);
+
+ void * rte_cryptodev_sym_session_get_private_data(
+ struct rte_cryptodev_sym_session *sess);
+
+
+For session-less mode, the private data information can be placed along with
the
+``struct rte_crypto_op``. The ``rte_crypto_op::private_data_offset`` indicates
the start
+of private data information. The offset is counted from the start of the
rte_crypto_op
+including initialization vector (IV).
