| | | | | | | xchacha is a chacha stream that allows for an extended nonce, which in turn makes it feasible to use random nonces. ok tb@

| | | | | | | a more appropriately licenced file. jsing and doug have rewritten these functions (including the comments) over the past years. ok jsing
* Provide the initial TLSv1.3 client implementation.jsing2019-01-215-25/+192
| | | | | | | | | Move tls13_connect() to a new tls13_client.c file and provide a legacy wrapper to it, which allocates a struct tls_ctx if necessary. Also move tls13_client_hello_send() to tls13_client.c and actual implement the building of a client hello. ok tb@
* Wire up the handshake message send and recv actions.jsing2019-01-212-4/+44
| | | | | | | This means that we actually receive and send handshake messages to and from the record layer. ok tb@
* In ssl_lib.c rev. 1.197, jsing@ added TLSv1.3 support to SSL_get_version(3).schwarze2019-01-211-2/+4
| | | | Document it.
* The main handshake loop can be shared between client and server.jsing2019-01-212-29/+15
| | | | | | | Pull the shared code up into a function and call it from tls13_connect() and tls13_accept() instead of duplicating it. "Yes, please!" tb@
* Use ssl_cipher_is_permitted() in ssl_cipher_list_to_bytes().tb2019-01-211-9/+6
| | | | ok jsing
* Add ssl_cipher_is_permitted(), an internal helper function thattb2019-01-213-2/+49
| | | | | | | will be used in a few places shortly, e.g. in ssl_cipher_list_to_bytes(). ok jsing
* Correct some rwstate handling that I broke when refactoring.jsing2019-01-211-3/+13
|
* Provide TLS 1.3 cipher AEAD/hash and legacy I/O handling functions.jsing2019-01-213-2/+210
| | | | | | | | | Provide functionality for determining AEADs and hashes for TLS 1.3 ciphers. Also provide wire read/write callbacks that interface with BIO and functions that interface between SSL_read/SSL_write and the TLS 1.3 record layer API. ok tb@
* Move struct tls13_ctx into a header since other things need access to it.jsing2019-01-213-21/+21
| | | | | | | | While here, rename struct handshake to struct handshake_stage to avoid potential ambiguity/conflict with the handshake data struct. Also add forward and back pointers between SSL and struct tls13_ctx. ok tb@
* Ensure we free TLS 1.3 handshake state.jsing2019-01-211-6/+11
| | | | | | | | There is no guarantee that ssl3_clear() is called before ssl3_free(), so free things here. Also move the chunk in ssl3_clear() up so that it is with the "free" code rather than the "reinit" code. ok beck@ tb@
* Teach ssl_version_string() about TLS1_3_VERSION.jsing2019-01-211-1/+3

* Store the record version and make it available for use.jsing2019-01-212-10/+21
| | | | | | While here correct an int vs size_t mismatch. ok tb@

|
* Provide a handshake message handling implementation for TLS 1.3.jsing2019-01-203-3/+213
| | | | | | | | It receives handshake messages by reading and parsing data from the record layer. It also provides support for building and sending handshake messages. ok tb@
* Provide an initial implementation of the TLS 1.3 record layer.jsing2019-01-203-6/+790
| | | | | | | | | | | This is entirely self-contained and knows nothing about SSL or BIO. The bottom of the stack is provided by wire read and write callbacks, with the API to the record layer primarily being via tls13_{read,write}_{application,handshake}_data(). This currently lacks some functionality, however will be worked on in tree. ok tb@
* Update record regress to match functionality changes.jsing2019-01-201-6/+37
|
* Provide a way to get just the record header.jsing2019-01-202-7/+33
| | | | | | Also check record size limits when reading records and setting data. ok tb@

* Add some internal consistency checks to the handshake state handling.jsing2019-01-201-9/+23
| | | | | | | | Fix the tls13_handshake_advance_state_machine() return value, which inadvertantly got flipped in an earlier commit. Also move this function to a more suitable location. ok tb@
* TLS 1.3 clients always need to send the supported groups extension.jsing2019-01-201-4/+5
| | | | | | A couple of cleanup/style tweaks while here. ok tb@

* Add handshake message type checking and special case certificate requests.jsing2019-01-191-1/+30
| | | | | | | | | | | | | | Check that the handshake message type received matches that required by the state machine. However, thanks to poor state design in the TLSv1.3 RFC, there is no way to know if you're going to receive a certificate request message or not, hence we have to special case it and teach the receive handler how to handle this situation. Discussed at length with beck@ and tb@ during the hackathon. ok tb@
* Tweak return value handling in the TLSv1.3 handshake code.jsing2019-01-192-44/+47
| | | | | | | | | | | | | The I/O paths are from the tls13_handshake_send_action() and tls13_handshake_recv_action() functions - both of these need to propagate I/O conditions (EOF, failure, want poll in, want poll out) up the stack, so we need to capture and return values <= 0. Use an I/O condition to indicate successful handshake completion. Also, the various send/recv functions are currently unimplemented, so return 0 (failure) rather than 1 (success). ok tb@
* Hook record regress.jsing2019-01-191-1/+3

* Add regress for TLSv1.3 record handling.jsing2019-01-192-0/+533
|
* Provide a TLS record handling implementation.jsing2019-01-193-2/+220
| | | | | | | | | | This is a self-contained struct and set of functions that knows how to decode and read a TLS record from data supplied via a read callback, and send itself via a write callback. This will soon be used to build the TLSv1.3 record layer handling code. ok beck@ tb@
