Short-term refactoring:
Refactoring:
- SSUSession:637, SSUSession:635 get rid of casting to SSUHeader
- Identity.cpp:156 check for self asignment
Long-term refactoring:
- Rely on a library for TLS and SSL.
- Move parsing code out of networking code, to allow better testing.
- Move streaming code to a separate directory.
- Separate front-end code (SAM, BOB, ...) from the back-end.
Additions:
- Write tests.
- Add documentation.
- Create a specialized IRC tunnel (instead of just a generic ClientTunnel instance).
- Ban peers with unexpected / bad behaviour.
- EdDSA support.
- Return correct error codes in HTTPProxy.
- Modify web interface layout and use AJAX to update information.
