* dtls/openssl.py:
- Added utility fucntions EC_curve_nist2nid() and EC_curve_nid2nist()
* dtls/patch.py:
- Extended wrap_socket() arguments with callbacks for user config functions of ssl context and ssl session values
- Extended SSLSocket() arguments with callbacks for user config functions of ssl context and ssl session values
* dtls/sslconnection.py:
- Extended SSLConnection() arguments with callbacks for user config functions of ssl context and ssl session values
- During the init of client and server the corresponding user config functions are called (if given)
- Added new classes SSLContext() [set_ciphers(), set_sigalgs(), set_curves(), set_ecdh_curve(), build_cert_chain(),
set_ssl_logging()] and SSL() [set_mtu(), set_link_mtu()]
* dtls/openssl.py:
- Added class _EllipticCurve() for easy handling of the builtin curves
- Added wrapper get_elliptic_curves() - which uses _EllipticCurve()
- Added EC_get_builtin_curves(), EC_KEY_new_by_curve_name() and EC_KEY_free()
- Added OBJ_nid2sn() for translating numeric ids to names
* dtls/util.py: Added _EC_KEY() derived from _Rsrc() with own free/del method
* dtls/err.py: Added error code ERR_WRONG_VERSION_NUMBER
* dtls/openssl.py: Added DTLS_server_method(), DTLSv1_2_server_method() and DTLSv1_2_client_method()
* dtls/patch.py: Default protocol DTLS for ssl.wrap_socket() and ssl.SSLSocket()
* dtls/sslconnection.py:
- Introduced PROTOCOL_DTLSv1_2 and PROTOCOL_DTLS (the latter one is a synonym for the "higher" version)
- Updated _init_client() and _init_server() with the new protocol methods
- Default protocol DTLS for SSLConnection()
- Return on ERR_WRONG_VERSION_NUMBER if client and server cannot agree on protocol version
* dtls/test/unit.py:
- Extended test_get_server_certificate() to iterate over the different protocol combinations
- Extended test_protocol_dtlsv1() to try the different protocol combinations between client and server
* dtls/openssl.py: Added mtu-functions SSL_set_mtu() and DTLS_set_link_mtu()
* dtls/prebuilt/win32-*: Updated libs for x86 and x86_64 to version 1.0.2l-dev
* dtls/sslconnection.py: mtu size set hardcoded to 1500 - otherwise the windows implementation has problems
* dtls/openssl.py:
- Added methods SSL_CTX_set_info_callback(), SSL_state_string_long(), SSL_alert_type_string_long() and SSL_alert_desc_string_long()
- Added constants for state and error evaluation during callback
* dtls/sslconnection.py: Added _ssl_logging_cb() as default callback function - only outputs messages when logger is active
* dtls/openssl.py: SSL_write() can handle ctypes.Array data
* dtls/sslconnection.py: Added missing import ERR_BOTH_KEY_CERT_FILES
* dtls/test/simple_client.py: Added basic test client to use with dtls/test/echo_seq.py
* dtls/openssl.py:
- Ordered constants according to header file from openSSL
- Beautified __all__-list and map for _make_function() in order to easy merges in the future
- Added a few returns in order to evaluate the success of the called methods
* dtls/patch.py: Grouped imports in the following order - system, local
* dtls/sslconnection.py: ssl protocol not hardcoded anymore for forked objects
* dtls/x509.py: logger messages working again
* dtls/openssl.py: support reading directly into given buffer instead
of forcing buffer copy (for ssl module compatibility)
* dtls/sslconnection.py: in-situ receive support, as above
* dtls/patch.py: various changes for compatibility with the ssl module
of Python 2.7.12; note that the ssl module's new
SSLContext is not supported
* dtls/test/unit.py: changes to support the updated ssl module,
including fix of deprecation warnings
* setup.py: increase version to 1.0.2
Increase version to 1.0.1, in preparation for PyPI release. This release
includes a fix by Jayson Vantuyl to an error code import. A proper error
is now emitted when omitting the keyfile on a PyDTLS server.
The version number is incremented to 1.0.0.
Thanks to doneir for reporting that a number of unit test were failing.
This was because two test certificates had expired. This commit replaces
these with updated certificates, along with the tool used for programmatic
certificate generation. The new certificates are set to remain valid for
approximately ten years.
