* RTG-3333 Support X25519MLKEM768 by default, but don't sent it as client
X25519MLKEM768 is the standardised successor of the preliminary
X25519Kyber768Draft00. Latest browsers have switched to X25519MLKEM768.
Cloudflare supports both on the edge.
We've had support for X25519MLKEM768 in this crate for a while, but
didn't enable by default. We're now enabling serverside support by
default. We also let clients advertise support when set
to kx-client-pq-supported.
We don't enable support by default yet for clients set to
kx-client-pq-preferred, as that would cause an extra round-trip due to
HelloRetryRequest if the server doesn't support X25519MLKEM768 yet.
BoringSSL against which we build must support X25519MLKEM768, otherwise
this will fail.
* replace once_cell with LazyLock
We can drop the once_cell dependency since the same functionality is
implemented in std now.
Requires bumping MSRV to 1.80.
* fix manual_c_str_literals clippy warning
* chore: Fix docs on SslRef::replace_ex_data
* Detailed error codes
* Clean up boring_sys::init()
We don't need the workaround that was initially introduced for a bug in
openssl, and OPENSSL_init_ssl always calls into CRYPTO_library_init on
boringssl, so just call it explicitly.
* Expose EVP_HPKE_KEY
* Expose client/server-side ECH
Resolves https://github.com/cloudflare/boring/issues/282
* Clean up ECH tests
* Expose SSL_set_enable_ech_grease
* update
* Use corresponds macro

Mid-handshake errors that occur before certificate verification
currently look like this:
```
TLS handshake failed: cert verification failed - Invalid certificate verification context [WRONG_VERSION_NUMBER]
```
Despite no certificate even being received yet, the error complains
about a failed verification. The cause here is that `cert verification
failed` is only omitted if the verification result is `OK`. The default
in BoringSSL before verification runs is `INVALID_CALL`, however.
`INVALID_CALL` is set/returned in these places:
- 44b3df6f03/src/ssl/internal.h (L3904)
- 44b3df6f03/src/ssl/ssl_session.cc (L396)
- 44b3df6f03/src/ssl/ssl_x509.cc (L713)
It is not used anywhere else as a verification result code. To improve
the error message, this commit adds `INVALID_CALL` as a verification
result for which no additional error is dislayed.
As of https://boringssl-review.googlesource.com/c/boringssl/+/64141,
X509_STORE_CTX_cleanup will zero the memory allocated to the
X509_STORE_CTX. Because X509StoreContextRef::init invokes
X509_STORE_CTX_cleanup once the with_context closure has finished,
calling X509StoreContextRef::verify_result (or any API really) is going
to be invalid because memory has been zerod out. This is a pretty big
footgun, so maybe we should consider screaming a bit louder for this
case.
As of https://boringssl-review.googlesource.com/c/boringssl/+/66288,
libssl allows a C++ runtime dependency. As such, we need to link with a
cpp runtime library. Implementation is inspired heavily from
54c956b2e6.
Before releasing this change, we'll need to figure out a way to support
this for windows.
