OHAI,
first of all, all that Yaron just wrote. Very much so.

No. I'm trying to assess if Tox is legitimately a better, or "better-stay-
away", alternative to Skype. So far I see three serious problems:
- no warning for users about a few things (like "Tox does not provide
anonymity", etc);
- written in C, and the code is "TFC" as defined in my mail in another
thread; ;)
- no good protocol documentation, so no way to to easily:
- write other implementations;
- assess the quality of the protocol.
Apart from these, there are the questions I brought up earlier, which might or
might not translate to more serious problems.
For the time being I'm going to use Tox for not-mission-critical stuff and
testing, and will suggest it to Skype users wanting to talk to me. I will not
advocate its use as a security tool.
Am I missing anything? Can anybody provide any answers to the questions I
mentioned, and provide below?
- does the transport layer have encryption? (does the middle layer do that
all or...?)
- where is the documentation of the cryptography?
- is there any hmac done at all?
- what is the tox id for a seed with all 0?
- how does the tox implementation handle different byte alignment?
- how does the tox implementation handle different byte endiness?
- how well stressed is the tox implementation? benchmarks?
- where is the rest of the documentation?
- where can I find a full view of how tox works from bottom to top?
