NO, stunnel does not support OCSP stapling. This is documented on the file TODO.md included in the source tar.gz file. If you need this feature badly, I guess you can sponsor Mike to implement it sooner.

# stunnel TODO

### High priority features

These features will likely be supported some day.

A sponsor could allocate my time to get them faster.

* Add client certificate autoselection based on the list of accepted issuers:

  SSL_CTX_set_client_cert_cb(), SSL_get_client_CA_list().

* Add an Apparmor profile.

* Optional line-buffering of the log file.

* Log rotation on Windows.

* Configuration file option to limit the number of concurrent connections.

* Command-line server control interface on both Unix and Windows.

* Separate GUI process running as the current user on Windows.

* An Android GUI.

* OCSP stapling (tlsext_status).

* Indirect CRL support (RFC 3280, section 5).

* MSI installer for Windows.

Regards,

Jose
