| | | | | | | | | | | | | | | | | | | | | | | | resumption, which would cause failures if doing a renegotiation under the same session (eg to refresh keys). The peer_certs variable was not set until after the Session object was created, meaning the session (or session ticket) would not include client certs. Worse, they would be included in the next session saved, so if a client presented one cert, then renegotiated and presented another one, the first cert would be associated with the second session!

| | | | | | | | | | | | | | | | | | | | | | | | | | the peer are automatically responded to. TLS::Channel::heartbeat can initiate a new heartbeat if the peer allows it. Heartbeat replies are passed back to the application processing function with an Alert value of HEARTBEAT_PAYLOAD (a 'fake' value, 256, which is out of range of the valid TLS alert space), along with the sent payload. The RFC requires us to have no more than one heartbeat 'in flight' at a time, ie without getting a response (or a timeout in the case of DTLS). Currently we do not prevent an application from requesting more.

| | | | | | | | | | | | | | | | | | | | Initial outline of server side SRP support. Need to figure out how to transfer the v, b, B params from the server key exchange message to the client key exchange. The DH variants do this by passing a Private_Key via server_kex_key call, but wrapping SRP params in a Private_Key really doesn't feel right. Not sure what to do here. Possibly both SRP and DH should return a Key_Exchange_Material* that a client key exchange knows how to dynamic cast on.

| | | | | | | | | | | | | | Make ciphersuite_list a free standing function Now the Policy interface only contains actual policy hooks (no non-virtual functions). Though choose_curve is a little dubious.
| * Limit the lifetime of tickets to Policy::session_ticket_lifetime()lloyd2012-04-0415-178/+196
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | seconds and report that value to the client in the NewSessionTicket message. After that point, a session ticket is ignored and a full renegotiation is forced. Only send a new session ticket on a new session, or on a resumed session where the client indicated it supports session tickets but for whatever reason didn't send one in the hello. Perhaps in this case, we should also remove the session from the session manager? Clean up server selection of the ciphersuite a bit, all in an anon function in tls_server instead of scattered over Server, Policy, and Server_Hello. Add Session::session_age and Session_Manager::session_lifetime
| * Add anonymous DH/ECDH ciphersuites to the cipher list. Interop checkedlloyd2012-04-022-18/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | against OpenSSL. One big issue that needs to be resolved is that with these ciphersuites available to be negotiated, we want to make sure they only are used when the application/user expects them to. Problem is that PSK and SRP are "anonymous" but authenticated via the shared secret. We need to be able to distinguish these on a policy level. Otherwise a MITM could simply offer anon DH, which would be somewhat unfortunate. A client could detect this in the handshake callback, but might not. In the short term to ensure this doesn't occur, disable both anon DH and PSK/SRP in the default policy.
| * Use SHA-256 when MD5 is negotiated as the HMAC hash in TLS 1.2,lloyd2012-04-022-2/+6
| | | | | | | | | | | | previously negotiating any MD5-based ciphersuite in TLS 1.2 would cause MAC failures as the master secret would come out differently due to using the wrong PRF.
| * Remove the Ciphersuite_Code enum and move all ciphersuitelloyd2012-03-307-351/+298
| | | | | | | | | | | | | | | | | | | | | | | | | | | | integer->info mapping to tls_suite_info.cpp which is mostly autogenerated by a Python script from the IANA parameters file. The SRP method now uses kex "SRP_SHA" which is what the RFC calls it. (And hypothetically, SRP_SHA256 might be defined at some point and we'd need to be able to distinguish them). Remove IDEA ciphersuite; we don't want to require IDEA be available due to the European patent still being valid (IIRC), but I didn't want to have to hand-edit the autogenerated switch with an #if check. Not a huge issue though as most sites don't support it anyway.

For some network approaches this won't make any difference but it might help with something doing direct writes on each callback. Additionally it seems important for DTLS, where each record must be contained in a single packet.

Avoid offering the session ticket extension if we know we don't have a key. For one thing it will cause us to avoid using stateful sessions, but additionally OpenSSL 1.0.1 is very intolerant of empty NewSessionTicket messages so definitely worth avoiding when we can.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | hello. Also include a full list of ciphersuites, ensuring that our original session ciphersuite is in the list regardless of policy (maybe it would be better to just not resume in that case, though?). Otherwise, if the server doesn't remember our session (or the session ticket key), it might not be capable of negotiating using the single ciphersuite we sent due to lack of information (allowed curves was a particular issue here). Including the full ciphersuite list also allows for rengotiating the ciphersuite if, for instance, the session can't be resumed because the server used to have an RSA cert but has since replaced it with an ECDSA cert.
