+====================
+
+`Name <#name>`__
+~~~~~~~~~~~~~~~~
+
+.. container::
+
+   FC_SetOperationState - restore the cryptographic operation state of a session.
+
+`Syntax <#syntax>`__
+~~~~~~~~~~~~~~~~~~~~
+
+.. container::
+
+   .. code:: eval
+
+      CK_RV FC_SetOperationState(
+        CK_SESSION_HANDLE hSession,
+        CK_BYTE_PTR pOperationState,
+        CK_ULONG ulOperationStateLen,
+        CK_OBJECT_HANDLE hEncryptionKey,
+        CK_OBJECT_HANDLE hAuthenticationKey
+      );
+
+`Parameters <#parameters>`__
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. container::
+
+   ``hSession``
+      [in] handle of the open session.
+   ``pOperationState``
+      [in] pointer to a byte array containing the operation state.
+   ``ulOperationStateLen``
+      [in] contains the total length (in bytes) of the operation state.
+   ``hEncryptionKey``
+      [in] handle of the encryption or decryption key to be used in a stored session or zero if no
+      key is needed.
+   ``hAuthenticationKey``
+      [in] handle of the authentication key to be used in the stored session or zero if none is
+      needed.
+
+`Description <#description>`__
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. container::
+
+   ``FC_SetOperationState`` restores the cryptographic operations state of a session from an array
+   of bytes obtained with ``FC_GetOperationState``. This function only works for digest operations
+   for now. Therefore, a user may call ``FC_SetOperationState`` without logging into the token (to
+   assume the NSS User role).
