* Finish up server side SRP support, a little ugly but it works.lloyd2012-04-061-1/+3
| | | | | | Add SRP hooks in the examples Fix next protocol support in the tls_server example.
* Re-enable TLS (was disabled by trunk merge), and require the srp6 modulelloyd2012-04-051-0/+4
| | | | | | | | | | 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.
* Initial client-side support for SRP (finally!). Tested against OpenSSLlloyd2012-04-051-0/+29
| | | | | 1.0.1, only the certificate versions tested currently as OpenSSL doesn't support anon SRP.
* Add an abstraction for reading handshake messages (as DTLS handles itlloyd2012-03-051-2/+2
| | | | | | | | quite differently). Avoid using a queue for reading certificates. Hide the version code in the handshake state with a getter and setter.

* In earlier versions, key exchange == "RSA" meant export-stylelloyd2012-01-251-3/+3
| | | | | | | | | | | | ephemeral RSA, and key exchange == "" meant RSA via the key in the server certificate. However we don't support any of the export suites anymore (and in fact that code probably never worked), so use kex algo == "RSA" to represent the server cert case as it's much easier to read the code and to understand from a policy configuration perspective. Also fix the default policy, "TripleDES" != "3DES" so we would not offer (as a client) and would reject (as a server) any 3DES ciphersuites.

* Don't assume the server key exchange consists of a series of BigInts.lloyd2012-01-241-4/+8
| | | | | | That happens to be true for DH and export RSA key exchanges but isn't true for ECDH or SRP. (It's almost true for SRP, but if the salt had a leading zero byte it would be lost in the conversion).

* Remove Handshake_Message::deserialize which was an unnecessary hook.lloyd2012-01-191-15/+7
| | | | | | Instead deserialize directly in the constructors that are passed the raw message data. This makes it easier to pass contextual information needed for decoding (eg, version numbers) where necessary.

* The server would incorrectly send a server key exchange message when alloyd2012-01-061-1/+1
| | | | | | | | | | | | | | | | | | pure RSA ciphersuite was negotiated. Detection of version rollback attacks with pure RSA ciphersuites was incorrect and would cause failures if the client supported a version we didn't (eg GnuTLS with TLS 1.2 enabled). Improve detection of SSLv2 client hellos. In particular, if a client that only supports SSLv2 connects, we will detect this case and send a protocol_version alert (which the SSLv2-only client will not understand, but a packet analyzer probably will) plus an exception with the message "Client claims to only support SSLv2, rejecting" instead of the previous much less helpful "Unknown record type" message. Remove vestigial support for RSA export ciphersuite key exchange.
* Add a function for getting the version number of an active connection.lloyd2011-12-301-1/+1
| | | | | | | | Add a new callback that is called with the session info when a handshake completes. Currently only called on the server side as the client doesn't have session resumption yet. Rename CipherSuite to TLS_Cipher_Suite.
