* Add support for DTLS timeouts (#1180)Jeremy Lainé2023-02-131-0/+3
| | | | | | | | | | | | Add support for DTLS timeouts When performing a DTLS handshake, the DTLS state machine may need to be updated based on the passage of time, for instance in response to packet loss. OpenSSL supports this by means of the `DTLSv1_get_timeout` and `DTLSv1_handle_timeout` methods, both of which are included in cryptography's bindings. This change adds Python wrappers for these methods in the `Connection` class.

* crypto._PassphraseHelper: pass non-callable passphrase using callback (#947)Huw Jones2020-10-121-1/+4
| | | | | | | | | | | | * crypto._PassphraseHelper: pass non-callable passphrase using callback Fixes #945 Before this commit, we would pass a bytes passphrase as a null terminated string. This causes issue when a randomly generated key's first byte is null because OpenSSL rightly determines the key length is 0. This commit modifies the passphrase helper to pass the passphrase via the callback * Update changelog to document bug fix
* Allow using additional untrusted certificates for chain building in ↵Sándor Oroszi2020-10-121-0/+3
| | | | | | | | | | | | X509StoreContext (#948) The additional certificates provided in the new `chain` parameter will be untrusted but may be used to build the chain. This makes it easier to validate a certificate against a store which contains only root ca certificates, and the intermediates come from e.g. the same untrusted source as the certificate to be verified.

* Allow using an OpenSSL hashed directory for verification in X509Store (#943)Sándor Oroszi2020-09-111-0/+3
| | | | | | | Add X509Store.load_locations() to set a CA bundle file and/or an OpenSSL- style hashed CA/CRL lookup directory, similar to the already existing SSL.Context.load_verify_locations(). Co-authored-by: Sandor Oroszi <sandor.oroszi@balabit.com>

Add Connection.get_verified_chain using SSL_get0_verified_chain if available (ie OpenSSL 1.1+) and X509StoreContext.get_verified_chain otherwise. Fixes #740. * TLSv1_METHOD -> SSLv23_METHOD * Use X509_up_ref instead of X509_dup * Add _openssl_assert where appropriate * SSL_get_peer_cert_chain should not be null * Reformat with black * Fix <OpenSSL.crypto.X509 object at 0x7fdbb59e8050> != <OpenSSL.crypto.X509 object at 0x7fdbb59daad0> * Add Changelog entry * Remove _add_chain

* ALPN: complete handshake without accepting a client's protocols. (#876)Mark Williams2019-11-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | * ALPN: complete handshake without accepting a client's protocols. The callback passed to `SSL_CTX_set_alpn_select_cb` can return `SSL_TLSEXT_ERR_NOACK` to allow the handshake to continue without accepting any of the client's offered protocols. This commit introduces `NO_OVERLAPPING_PROTOCOLS`, which the Python callback passed to `Context.set_alpn_select_callback` can return to achieve the same thing. It does not change the previous meaning of an empty string, which still terminates the handshake. * Update src/OpenSSL/SSL.py Co-Authored-By: Alex Gaynor <alex.gaynor@gmail.com> * Address @alex's review. * Use recorded value in test, fix lint error. * Cover TypeError branch in _ALPNHelper.callback

* bump the minimum cryptography version (#875)Paul Kehrer2019-11-171-0/+2
| | | | | | | Users with older cryptography (and hence potentially older asn1crypto, a transitive dependency) are seeing a serious bug on macOS catalina due to the way older asn1crypto loads a shared library. While this isn't a pyOpenSSL bug bumping this dep might prevent the bug from impacting some users.
