      Add TLSv1.3 post-handshake authentication (PHA) · 9d75dce3
      由 Todd Short 提交于 
      Add SSL_verify_client_post_handshake() for servers to initiate PHA

Add SSL_force_post_handshake_auth() for clients that don't have certificates
initially configured, but use a certificate callback.

Update SSL_CTX_set_verify()/SSL_set_verify() mode:

* Add SSL_VERIFY_POST_HANDSHAKE to postpone client authentication until after
the initial handshake.

* Update SSL_VERIFY_CLIENT_ONCE now only sends out one CertRequest regardless
of when the certificate authentication takes place; either initial handshake,
re-negotiation, or post-handshake authentication.

Add 'RequestPostHandshake' and 'RequirePostHandshake' SSL_CONF options that
add the SSL_VERIFY_POST_HANDSHAKE to the 'Request' and 'Require' options

Add support to s_client:
* Enabled automatically when cert is configured
* Can be forced enabled via -force_pha

Add support to s_server:
* Use 'c' to invoke PHA in s_server
* Remove some dead code

Update documentation

Update unit tests:
* Illegal use of PHA extension
* TLSv1.3 certificate tests

DTLS and TLS behave ever-so-slightly differently. So, when DTLS1.3 is
implemented, it's PHA support state machine may need to be different.
Add a TODO and a #error

Update handshake context to deal with PHA.

The handshake context for TLSv1.3 post-handshake auth is up through the
ClientFinish message, plus the CertificateRequest message. Subsequent
Certificate, CertificateVerify, and Finish messages are based on this
handshake context (not the Certificate message per se, but it's included
after the hash). KeyUpdate, NewSessionTicket, and prior Certificate
Request messages are not included in post-handshake authentication.

After the ClientFinished message is processed, save off the digest state
for future post-handshake authentication. When post-handshake auth occurs,
copy over the saved handshake context into the "main" handshake digest.
This effectively discards the any KeyUpdate or NewSessionTicket messages
and any prior post-handshake authentication.

This, of course, assumes that the ID-22 did not mean to include any
previous post-handshake authentication into the new handshake transcript.
This is implied by section 4.4.1 that lists messages only up to the
first ClientFinished.

      Add support for the TLS 1.3 signature_algorithms_cert extension · c589c34e
      由 Benjamin Kaduk 提交于 
      The new extension is like signature_algorithms, but only for the
signature *on* the certificate we will present to the peer (the
old signature_algorithms extension is still used for signatures that
we *generate*, i.e., those over TLS data structures).

We do not need to generate this extension, since we are the same
implementation as our X.509 stack and can handle the same types
of signatures, but we need to be prepared to receive it, and use the received
information when selecting what certificate to present.

There is a lot of interplay between signature_algorithms_cert and
signature_algorithms, since both affect what certificate we can
use, and thus the resulting signature algorithm used for TLS messages.
So, apply signature_algorithms_cert (if present) as a filter on what
certificates we can consider when choosing a certificate+sigalg
pair.

As part of this addition, we also remove the fallback code that let
keys of type EVP_PKEY_RSA be used to generate RSA-PSS signatures -- the
new rsa_pss_pss_* and rsa_pss_rsae_* signature schemes have pulled
the key type into what is covered by the signature algorithm, so
we should not apply this sort of compatibility workaround.

      Propagate TLS 1.3 sigalgs through tls1_set_sigalgs() · fd5e1a8c
      由 Benjamin Kaduk 提交于 
      Our historical SSL{,_CTX}_set_sigalgs() APIs take an array of
NID pairs (hash and signature), and our parser for manually
specifying unified sigalgs (that do not necessarily correspond
to an actual signature+hash pair) was transiting via (the implementation
of) this historical API.  The TLS 1.3 draft-23 has introduced
signature schemes that have identical signature type and hash type,
differing only in the (RSA) public key OID, which prevents
the rsa_pss_pss_* schemes from being properly identified and
sent on the wire.

To fix the issue, parse sigalg strings directly into SIGALG_LOOKUP
objects, and pass around an array of uint16 wire protocol values
instead of NID pairs.  The old interface is retained for API
compatibility but will become less and less useful with time.

      Add TLS 1.3 draft-23 PSS signature algorithms · f55e99f7
      由 Benjamin Kaduk 提交于 
      We now have a split in the signature algorithms codepoint space for
whether the certificate's key is for rsaEncryption or a PSS-specific
key, which should let us get rid of some special-casing that we
previously needed to try to coax rsaEncryption keys into performing PSS.
(This will be done in a subsequent commit.)

Send the new PSS-with-PSS-specific key first in our list, so that
we prefer the new technology to the old one.

We need to update the expected certificate type in one test,
since the "RSA-PSS+SHA256" form now corresponds to a public key
of type rsaEncryption, so we should expect the server certificate
type to be just "RSA".  If we want to get a server certificate
type of "RSA-PSS", we need to use a new signature algorithm
that cannot be represented as signature+hash, so add a test for that
as well.

      Session resume broken switching contexts · a84e5c9a
      由 Todd Short 提交于 
      When an SSL's context is swtiched from a ticket-enabled context to
a ticket-disabled context in the servername callback, no session-id
is generated, so the session can't be resumed.

If a servername callback changes the SSL_OP_NO_TICKET option, check
to see if it's changed to disable, and whether a session ticket is
expected (i.e. the client indicated ticket support and the SSL had
tickets enabled at the time), and whether we already have a previous
session (i.e. s->hit is set).

In this case, clear the ticket-expected flag, remove any ticket data
and generate a session-id in the session.

If the SSL hit (resumed) and switched to a ticket-disabled context,
assume that the resumption was via session-id, and don't bother to
update the session.

Before this fix, the updated unit-tests in 06-sni-ticket.conf would
fail test #4 (server1 = SNI, server2 = no SNI).
