This initial commit for the PyDTLS package includes the following functionality:
* DTLS cookie exchange, using secure hmac cookies
* A platform-independent routing UDP demultiplexer
* SSL handshaking over UDP using the DTLS protocol
* Datagram exchange using the DTLS protocol
* SSL shutdown over UDP
The package is structured as follows:
* dtls: top-level package
* dtls.demux: demultiplexer package; automatically loads a
demultiplexer appropriate for the currently executing
platform
* dtls.demux.router: a routing demux for platforms whose network stacks
cannot assign incoming UDP packets to sockets based
on the sockets' connection information
* dtls.demux.osnet: a demux that uses the operating system's UDP packet
routing functionality
* dtls.err: package-wide error handling and error definitions
* dtls.sslconnection: a client and server-side connection class for
UDP network connections secured with the DTLS protocol
* dtls.openssl: a ctypes-based wrapper for the OpenSSL library
* dtls.test: test scripts, utilities, and unit tests
The following binaries are provided:
* libeay32.dll: cryptographic portion of the OpenSSL library
* ssleay32.dll: protocol portion of the OpenSSL library (depends on former)
* cygcrypto-1.0.0.dll: as libeay32.dll, but with debugging symbols
* cygssl-1.0.0.dll: as ssleay32.dll, but with debugging symbols
All binaries have been built with the MinGW tool chain, targeted for msvcr90.
The unstripped dll's can be debugged on Windows with gdb. Cygwin is not used.

"""UDP Demux
|
|
|
|
A UDP demux is a wrapper for a datagram socket. The demux must be initialized
|
|
with an unconnected datagram socket, referred to as the root socket. Once
|
|
initialized, the demux will create new connections to peer endpoints upon
|
|
arrival of datagrams from a new endpoint. Such a connection is of a
|
|
socket-derived type, and will receive datagrams only from the peer endpoint for
|
|
which it was created, and that are sent to the root socket.
|
|
|
|
Connections must be used for receiving datagrams only. Outgoing traffic should
|
|
be sent through the root socket.
|
|
|
|
Varying implementations of this functionality are provided for different
|
|
platforms.
