Selene - A SSL/TLS library

Selene has a few goals that makes it different from a more traditional SSL libraries:

• Completely Asynchronous: Selene does no IO itself, it only provides notifications to the user that IO should be done.

• Asynchronous Callbacks: Callback functions provide their own callback to notify Selene when the user has finished an operation.

• Test Driven: A test framework to test all code paths.

• Plugable Backends for Cryptography: Currently only focusing on OpenSSL, but others are possible.

• Liberal License: Under the Apache License, version 2.0.

Selene is named after the Greek Goddess of the Moon, because I am terrible at naming projects.

Status

A prototype backend (openssl-threaded) was used to validate the basics of the selene_* API. I am currently slowly working on the native Selene TLS backend, which only uses OpenSSL for cryptographic operations, but not the actual protocol parsing.

Hacking Notes:

• All contributors must sign an Apache Software Foundation CLA, and agree that Selene may be moved to the ASF at a future date.
• External Functions and types are prefixed with selene_*
• Internal Functions and types are prefixed with sln_*
• Style: Google C++ Style Guide, even though this is C. Use clang-format -style=Google on all source code.
• Write test cases for all code paths, including errors.
