Summary

Two self-contained pieces of #8007 (@im-0), applied to the rustls backend we
already have. That PR is marked DO NOT MERGE and rewrites the backend as a
whole; this takes only the two parts that stand on their own, with @im-0
credited as co-author on both commits.

`ssl/oid.rs` — read the OID table out of OpenSSL's object database

The hand-written table is replaced by a parse of OpenSSL's own obj_mac.num
and objects.txt, vendored under crates/stdlib/rustls-data/ from #8007, so
the NIDs, names and dotted OIDs are OpenSSL's rather than transcribed:

An object whose short-name column is blank carries its long name as both,
which is what OBJ_nid2sn(NID_pkcs9_emailAddress) answers.
140 objects have a NID and no OID — the algorithm names like DES-EDE3, and
the bare roots iso / itu-t, since DER packs the first two arcs into one
byte. nid2obj reports None for the fourth field of those.
Lookups keep the first object carrying a repeated name or OID, as OpenSSL's
own do.

`ssl/cipher.rs` — parse OpenSSL cipher strings

set_ciphers matched a handful of patterns (ALL / DEFAULT / HIGH,
substring tests, ! and + terms skipped). It now takes the grammar
man openssl-ciphers documents, ported from #8007: !, -, +,
@STRENGTH, @SECLEVEL=n, +-joined conjunctions, the DEFAULT / ALL /
COMPLEMENTOF* groups, protocol versions, SUITEB* (which also pins its key
exchange groups, per RFC 6460), and the aXXX / kXXX / eXXX prefixes.

Nine defects in that block were fixed while porting it, each found by the
comparison below: MEDIUM and LOW selected the whole default list; AES,
ECDH and kECDHE selected nothing; SHA256 / SHA384 matched the
handshake hash in a suite's name instead of a MAC; the TLSv1.0 / SSLv3
arms let a conjunction through unfiltered; and the selection was built by
iterating HashMaps, so its order — the preference order offered to the peer
— differed from run to run. The table is an ordered Vec now.

Behaviour changes worth a review

set_ciphers raises SSLError("No cipher can be selected.") when the
string selects nothing, which is the one failure SSL_CTX_set_cipher_list
reports. Strings naming only families rustls does not implement — PSK,
SRP, DHE, kRSA, ADH, eNULL, CBC, MEDIUM, the digest names —
therefore raise where they used to succeed and leave the defaults selected.
The TLS 1.3 suites stay selected whatever the string says, in provider
order, because that setter does not reach them. A string naming only those
still selects nothing, as OpenSSL's does.
CryptoExt gains a default_cipher_suites field, so that DEFAULT and
ALL are distinguishable; examples/custom_tls_providers.rs shows the
update a downstream constructor needs.

Testing

cargo test -p rustpython-stdlib --no-default-features --features ssl-rustls,rustls/aws_lc_rs ssl — 17 passed.
cargo test and cargo clippy --workspace --all-targets with CI's feature
set — clean.
./target/release/rustpython -m test test_ssl — 196 run, 43 skipped, 0
failed, matching a build of main measured the same way.
Both slices were checked against CPython's OpenSSL over their full input
range rather than by spot checks. Every NID _ssl.nid2obj answers was
compared with the new table; 78 cipher strings were compared through
set_ciphers + get_ciphers. The selections agree except under
@SECLEVEL=n, which OpenSSL applies at handshake time while this applies it
to the selection, and except for the families rustls has no suite for. No
string is accepted here that OpenSSL rejects.

          ssl: read the OID table out of OpenSSL's object database

453fc20

`txt2obj` and `nid2obj` have to answer with OpenSSL's own numbers, and the
table behind them was 39 entries transcribed by hand, so every object
outside that set was reported unknown.

Read OpenSSL's own files instead: `obj_mac.num` carries each object's NID
and `objects.txt` carries its OID, short name and description, and the
identifier `objects.pl` derives per object -- the `!Cname` override, else
the description, else the short name, each qualified by the enclosing
`!module` with `-` spelled `_` -- joins the two.  `OidEntry`, `OidTable`
and the `find_by_*` functions keep their shape, so `ssl.rs` only changes
where an object has no OID to report.

Three details the object database settles that a curated table did not
have to:

- an object written with one name carries it as both, so
  `nid2obj(48)` is `('emailAddress', 'emailAddress', ...)`;
- an object need not have an OID at all -- `DES-EDE3` and 139 other
  algorithm names have a NID and nothing to encode -- so the fourth
  field of the tuple is None for those, as it is on OpenSSL;
- one arc does not encode, since DER packs the first two into a byte,
  so the bare roots `iso` and `itu-t` are OID-less too, while two arcs
  such as X500's `2.5` are a real object.

Checked against `_ssl.nid2obj` on CPython built with OpenSSL, over every
NID it answers: 1387 of its 1390 present, with no disagreement on any of
them, up from 39.  The three absent are OpenSSL's unnamed placeholder
slots, which it reports as ('NULL', 'NULL', None).

The data files come from openssl/openssl `crypto/objects/`, via the
rustls integration rewrite in RustPython#8007.

          ssl: parse OpenSSL cipher strings in set_ciphers

42295a0

Replaces the pattern matcher `set_ciphers` used with the grammar
`man openssl-ciphers` documents, in a new `ssl/cipher.rs` taken from
RustPython#8007: `!`, `-`, `+`, `@STRENGTH`, `@SECLEVEL=n`, `+`-joined
conjunctions, the DEFAULT/ALL/COMPLEMENTOF* groups, protocol versions,
SUITEB*, and the aXXX/kXXX/eXXX prefixes.

`set_ciphers` raises "No cipher can be selected." for a string that
names nothing the provider offers, which is the one failure
SSL_CTX_set_cipher_list reports, and keeps the TLS 1.3 suites selected
in provider order because that setter does not reach them. A SUITEB*
string pins its own key exchange groups, which `prepare_kx_groups`
now reads.

Against CPython's OpenSSL over 78 cipher strings, the selections agree
except under `@SECLEVEL=n`, which OpenSSL applies at handshake time and
this applies to the selection.

`CryptoExt` gains `default_cipher_suites` so that `DEFAULT` and `ALL`
are distinguishable.

📝 Walkthrough

Walkthrough

The change adds OpenSSL-compatible cipher-string parsing, imports OpenSSL OID databases, separates provider default cipher suites from all suites, and wires Suite B groups and OID-less objects into SSL behavior.

Changes

TLS and OpenSSL integration

Layer / File(s)	Summary
OpenSSL OID registry loading `crates/stdlib/rustls-data/*`, `crates/stdlib/src/ssl/oid.rs`	The OID table now parses OpenSSL data files. It supports aliases, modules, duplicate handling, OID-less entries, canonical OID input, and expanded validation.
Provider default cipher contracts `crates/stdlib/src/ssl/providers.rs`, `examples/custom_tls_providers.rs`, `src/interpreter.rs`	`CryptoExt` now stores cipher suites selected by `DEFAULT`. Provider configurations initialize this field and handle FIPS suite lists.
OpenSSL cipher-string parser `crates/stdlib/src/ssl/cipher.rs`, `.cspell.json`	The parser supports cipher names, groups, conjunctions, ordering and deletion operators, security levels, and Suite B selectors. Tests cover supported and rejected expressions.
SSL context cipher and OID wiring `crates/stdlib/src/ssl.rs`, `crates/stdlib/src/ssl/compat.rs`	`set_ciphers` uses the new parser, stores Suite B key-exchange groups, applies provider TLS 1.3 defaults, validates curves, updates BIO reads, and returns `None` for objects without OIDs.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to 5a5d3

This change substantially expands TLS cipher configuration behavior and OID compatibility. Unresolved cipher-policy parsing and server configuration caching concerns could cause configured TLS policies not to take effect as intended, so these issues should be addressed before merge.

          ssl: finish cipher reporting and provider handling

9a0aaf7

Use the provider-ordered cipher metadata table as the single source for parsing, reporting, OpenSSL names and descriptions. This makes get_ciphers reflect the context selection and validates curves and Suite B against the active provider.

Keep set_ciphers from changing TLS 1.3 suites, preserve the provider's order, fix empty conjunctions, and keep FIPS initialization within the provider's filtered cipher and key-exchange defaults.

Invalidate the cached server configuration after changing cipher selection.

When set_ciphers() runs after a server configuration has been built, these assignments update the context state, but initialize_server_connection() reuses ctx.server_config at Lines 3328-3341. Later non-SNI server sockets therefore continue to use the old cipher list and Suite B groups. Clear server_config when storing the new selection.

string pins its own key exchange groups, which `prepare_kx_groups`
now reads.

Against CPython's OpenSSL over 78 cipher strings, the selections agree
except under `@SECLEVEL=n`, which OpenSSL applies at handshake time and
this applies to the selection.

`CryptoExt` gains `default_cipher_suites` so that `DEFAULT` and `ALL`
are distinguishable.

* ssl: finish cipher reporting and provider handling

Use the provider-ordered cipher metadata table as the single source for parsing, reporting, OpenSSL names and descriptions. This makes get_ciphers reflect the context selection and validates curves and Suite B against the active provider.

Keep set_ciphers from changing TLS 1.3 suites, preserve the provider's order, fix empty conjunctions, and keep FIPS initialization within the provider's filtered cipher and key-exchange defaults.

* ssl: preserve OpenSSL OID lookup rules

Keep object-name lookup case-sensitive and canonicalize numeric OID arcs before consulting the generated OpenSSL object table.

* ssl: preserve cleartext after MemoryBIO shutdown

Read at most one TLS record while waiting for close_notify in BIO mode, leaving any post-TLS cleartext queued for the BIO owner.

* ssl: reject empty cipher conjunction operands

Keep empty operands visible to the parser so malformed OpenSSL cipher strings such as AES+ and ALL++AES are rejected instead of normalized.

* ssl: make Suite B cipher ids unambiguous

Spell out the u16 conversion so Windows-only iterator implementations cannot make collection type inference ambiguous.

* ssl: move native certificate loading behind host_env

Keep platform trust-store loading and filesystem predicates on the host boundary while exposing backend-neutral certificate bytes to the rustls integration.

* ssl: invalidate server config after cipher changes

Rebuild cached server configuration after set_ciphers updates the selected suites or Suite B key-exchange groups.

* ssl: load default certificate sources independently

Honor SSL_CERT_FILE and SSL_CERT_DIR independently. Keep directory certificates as lazy capath candidates, and fall back to native roots only when no environment certificate file was loaded.
