# Change Log

## [Unreleased]

## [v0.10.81] - 2026-06-12

### Fixed

* `SslContextRef::verify_mode` and `SslRef::verify_mode` no longer panic when the verify mode contains bits not modeled by `SslVerifyMode`.

### Added

* Added `SslVerifyMode::CLIENT_ONCE` and `SslVerifyMode::POST_HANDSHAKE`.
* Added `X509CrlBuilder` and `X509RevokedBuilder`, for building and signing CRLs, along with the `CrlNumber` extension builder.
* Added `Nid::BRAINPOOL_P224R1` and `Nid::BRAINPOOL_P224T1`.
* Added `Asn1StringRef::to_string`, which converts the string to UTF-8 without truncating at interior NUL bytes.

### Changed

* Deprecated `Asn1StringRef::as_utf8`, which truncates at the first interior NUL byte, in favor of `Asn1StringRef::to_string`.

## [v0.10.80] - 2026-05-16

### Fixed

* Fixed a buffer overflow in `CipherCtxRef::cipher_update_inplace` when used with AES key-wrap-with-padding ciphers.

## [v0.10.79] - 2026-05-03

### Changed

* Bumped MSRV to 1.80.
* Removed the `once_cell` dependency in favor of `std::sync::{LazyLock, OnceLock}`.
* Deprecated `EcPointRef::mul`, `EcPointRef::mul_generator`, and `EcPointRef::invert` in favor of `mul2`, `mul_generator2`, and `invert2`, which take `&mut BigNumContextRef`. The deprecated methods accepted a shared reference despite mutating the `BN_CTX`, which was unsound under `Send + Sync`.

### Added

* Added `EcGroupRef::generator_opt`, which returns `Option<&EcPointRef>`.
* Added `PKeyRef::seed_into`, which writes the algorithm-defined seed of an ML-DSA or ML-KEM private key into a caller-supplied buffer. The inverse of `PKey::private_key_from_seed`.
* Added `PKey::private_key_from_seed`, which constructs ML-DSA and ML-KEM private keypairs from a `seed` `OSSL_PARAM` via `EVP_PKEY_fromdata`. Requires OpenSSL 3.5 or newer at runtime.
* Added `PKeyRef::is_a` and the `KeyType` algorithm-name newtype, for identifying provider-supplied keys (such as ML-DSA) where `EVP_PKEY_id` returns `-1`.
* Added `PKey::public_key_from_raw_bytes_ex` and `PKey::private_key_from_raw_bytes_ex`, which take a `KeyType` and accept an optional library context and property query string. Required for provider-supplied algorithms with no associated `Id`, such as ML-DSA.
* Added `PkeyCtxRef::set_context_string`, which binds a context string to an ML-DSA signing or verification operation. Requires OpenSSL 3.5 or newer.
* Added `EcPointRef::mul2`, `EcPointRef::mul_generator2`, and `EcPointRef::invert2`, which take `&mut BigNumContextRef`.

### Fixed

* `EcGroupRef::generator` no longer constructs a reference from a NULL pointer when the group has no generator set (e.g. a group built with `EcGroup::from_components` before `set_generator` is called), which was immediate undefined behavior. It now panics in that case and has been deprecated in favor of `EcGroupRef::generator_opt`.
* `X509Ref::ocsp_responders` now validates each accessLocation as UTF-8 and returns an `ErrorStack` if any entry is not, rather than constructing a `&str` containing invalid UTF-8 (language-level UB triggerable by a malicious certificate).
* Fixed a process abort that could occur when the SSL verify, PSK client, or PSK server callback fired after the underlying `SSL_CTX` had been swapped.
* Fixed an output-buffer overflow in `CipherCtxRef::cipher_update` and `cipher_update_vec` when used with AES key-wrap-with-padding ciphers, which emit up to `input.len() + 15` bytes during the update call rather than the previously assumed `input.len() + block_size`.

## [v0.10.78] - 2026-04-19

### Added

* Added support for OpenSSL 4.x.
* Added support for LibreSSL 4.3.x.

### Fixed

* Fixed several soundness issues where safe Rust callers could trigger out-of-bounds reads or writes:
    * `MdCtxRef::digest_final` now returns an error when the output buffer is shorter than the digest size.
    * `PkeyCtxRef::derive` now checks the output buffer length on OpenSSL 1.1.x and LibreSSL, where some key types (X25519, X448, HKDF-extract) ignore the caller-supplied length.
    * Callbacks for key-loading passwords and SSL PSK and cookie generation now reject values longer than the length of the slice.
    * Fixed a dangling stack pointer in the SSL custom extension callback when using a fixed-length array.
    * Fixed an inverted bounds assertion in AES key unwrap.
* `Crypter::new` now panics, as documented, when an IV is required by the cipher but not provided (previously it silently used an all-zero IV).
* Avoided a panic when formatting overlong OIDs; the value is now truncated with trailing dots.
* Fixed Suite B flag assignments in `X509VerifyParam`.
* Handle errors on `OPENSSL_malloc` in `PkeyCtxRef::set_rsa_oaep_label`.

## [v0.10.77] - 2026-04-12

### Added

* Enabled `MdCtxRef::digest_sign`, `MdCtxRef::digest_sign_to_vec`, `MdCtxRef::digest_verify`, and `MdCtxRef::reset` on BoringSSL, LibreSSL, and AWS-LC.

## [v0.10.76] - 2026-03-11

### Added

* Added brainpool curve NID constants.

* Enhanced `Debug` implementation for `Nid`.
* Constified `PKey::from_raw`.
* Exposed `from_str_x509()` for LibreSSL >= 3.6.0.

### Fixed

* Fixed use-after-free of error strings on BoringSSL/aws-lc.
* Fixed cipher comparison (`is_ccm`, `is_ocb`) to use NID instead of unreliable pointer comparison. Added NID constants for `AES_*_OCB`.
* Fixed invalid value parsing of OCSP revocation reason.
* Fixed `BIO_METHOD` path for AWS-LC to use BoringSSL codepath.

## [v0.10.75] - 2025-11-07

### Added

* Added support for `set_rsa_oaep_label` on AWS-LC/BoringSSL.
* Added `Asn1GeneralizedTime::from_str`.
* Added `OcspStatus::next_update` method.

### Fixed

* Fixed unsound OCSP `find_status` handling of optional next_update field. If an OCSP response does not have a `nextUpdate`, `OcspStatus::next_update` will store a sentinel value. Use `OcspStatus::next_update()` instead.

### Deprecated

* Deprecated `OcspStatus::next_update` field in favor of the `next_update()` method.

## [v0.10.74] - 2025-10-14

## [v0.10.72] - 2025-04-04

### Fixed

### Fixed

* Fixed injection vulnerabilities where OpenSSL's configuration mini-language could be used via `x509::extension::SubjectAlternativeName` and `x509::extension::ExtendedKeyUsage`. The mini-language can read arbitrary files amongst other things.
  * As part of fixing this `SubjectAlternativeName::dir_name` and `SubjectAlternativeName::other_name` are deprecated and their implementations always `panic!`. If you have a use case for these, please file an issue.
* Fixed several NULL pointer dereferences in OpenSSL that could be triggered via `x509::X509Extension::new` and `x509::X509Extension::new_nid`. Note that these methods still accept OpenSSL's configuration mini-language, and therefore should not be used with untrusted data.

## [v0.10.2] - 2018-01-11

### Added

* Added `ConnectConfiguration::set_use_server_name_indication` and
    `ConnectConfiguration::set_verify_hostname` for use in contexts where you don't have ownership
    of the `ConnectConfiguration`.

## [v0.10.1] - 2018-01-10

### Added

* Added a `From<ErrorStack> for ssl::Error` implementation.

## [v0.10.0] - 2018-01-10

### Compatibility

* openssl 0.10 still uses openssl-sys 0.9, so openssl 0.9 and 0.10 can coexist without issue.

### Added

* The `ssl::select_next_proto` function can be used to easily implement the ALPN selection callback
    in a "standard" way.
* FIPS mode support is available in the `fips` module.
* Accessors for the Issuer and Issuer Alternative Name fields of X509 certificates have been added.
* The `X509VerifyResult` can now be set in the certificate verification callback via
    `X509StoreContextRef::set_error`.

### Changed

* All constants have been moved to associated constants of their type. For example, `bn::MSB_ONE`
    is now `bn::MsbOption::ONE`.
* Asymmetric key types are now parameterized over what they contain. In OpenSSL, the same type is
    used for key parameters, public keys, and private keys. Unfortunately, some APIs simply assume
    that certain components are present and will segfault trying to use things that aren't there.

    The `pkey` module contains new tag types named `Params`, `Public`, and `Private`, and the
    `Dh`, `Dsa`, `EcKey`, `Rsa`, and `PKey` have a type parameter set to one of those values. This
    allows the `Signer` constructor to indicate that it requires a private key at compile time for
    example. Previously, `Signer` would simply segfault if provided a key without private
    components.
* ALPN support has been changed to more directly model OpenSSL's own APIs. Instead of a single
    method used for both the server and client sides which performed everything automatically, the
    `SslContextBuilder::set_alpn_protos` and `SslContextBuilder::set_alpn_select_callback` handle
    the client and server sides respectively.
* `SslConnector::danger_connect_without_providing_domain_for_certificate_verification_and_server_name_indication`
    has been removed in favor of new methods which provide more control. The
    `ConnectConfiguration::use_server_name_indication` method controls the use of Server Name
    Indication (SNI), and the `ConnectConfiguration::verify_hostname` method controls the use of
    hostname verification. These can be controlled independently, and if both are disabled, the
    domain argument to `ConnectConfiguration::connect` is ignored.
* Shared secret derivation is now handled by the new `derive::Deriver` type rather than
    `pkey::PKeyContext`, which has been removed.
* `ssl::Error` is now no longer an enum, and provides more direct access to the relevant state.
* `SslConnectorBuilder::new` has been moved and renamed to `SslConnector::builder`.
* `SslAcceptorBuilder::mozilla_intermediate` and `SslAcceptorBuilder::mozilla_modern` have been
    moved to `SslAcceptor` and no longer take the private key and certificate chain. Install those
    manually after creating the builder.
* `X509VerifyError` is now `X509VerifyResult` and can now have the "ok" value in addition to error
    values.
* `x509::X509FileType` is now `ssl::SslFiletype`.
* Asymmetric key serialization and deserialization methods now document the formats that they
    correspond to, and some have been renamed to better indicate that.

### Removed

* All deprecated APIs have been removed.
* NPN support has been removed. It has been supersceded by ALPN, and is hopefully no longer being
    used in practice. If you still depend on it, please file an issue!
* `SslRef::compression` has been removed.
* Some `ssl::SslOptions` flags have been removed as they no longer do anything.
