NEWS

== Version 1.7.0 ==

webauthn-server-attestation:

* Updated name of AAGUID `2fc0579f811347eab116bb5a8db9202a` to "YubiKey 5/5C NFC"
* Changed name of "YubiKey 5 Series security key" to "YubiKey 5 Series"

webauthn-server-core:

Changes:

* Fixed crash on unknown attestation statement formats
 ** Unless `RelyingParty.allowUntrustedAttestation` is set to `false`, unknown
    attestation statements will now pass as untrusted attestations, instead of
    throwing an IllegalArgumentException.
* Disambiguated Jackson deserialization of class `AuthenticatorTransport`

New features:

* Class `RegisteredCredential` can now be serialized to and deserialized from
  JSON.


== Version 1.6.4 ==

* Changed dependency declarations to version ranges
* Bumped Guava dependency to version [24.1.1,30) in response to CVE-2018-10237


== Version 1.6.3 ==

webauthn-server-attestation:

* Added new YubiKey AAGUIDs to metadata.json


webauthn-server-core:

* Bumped Jackson dependency to version 2.11.0 in response to CVEs:
 ** CVE-2020-9546
 ** CVE-2020-10672
 ** CVE-2020-10969
 ** CVE-2020-11620
* Fixed incorrect JavaDoc on AssertionResult.isSignatureCounterValid(): it will
  also return true if both counters are zero.


== Version 1.6.2 ==

* Fixed dependencies missing from release POM metadata


== Version 1.6.1 ==

Security fixes:

* Bumped Jackson dependency to version 2.9.10.3 in response to CVE-2019-20330
  and CVE-2020-8840


== Version 1.6.0 ==

Security fixes:

* Bumped Jackson dependency to version 2.9.10.1 which has patched CVE-2019-16942

`webauthn-server-core`:

Bug fixes:

* Fixed bug introduced in 1.4.0, which caused
  `RegistrationResult.attestationMetadata` to always be empty.


`webauthn-server-attestation`:

* New enum constant `Transport.LIGHTNING`
* Fixed transports field of YubiKey NEO/NEO-n in `metadata.json`.
* Added YubiKey 5Ci to `metadata.json`.
* Most `deviceUrl` fields in `metadata.json` changed to point to stable
  addresses in Yubico knowledge base instead of dead redirects in store.


== Version 1.5.0 ==

Changes:

* `RelyingParty` now makes an immutable copy of the `origins` argument, instead
  of storing a reference to a possibly mutable value.
* The enum `AuthenticatorTransport` has been replaced by a value class
  containing methods and value constants equivalent to the previous enum.
* The return type of `PublicKeyCredentialDescriptor.getTransports()` is now a
  `SortedSet` instead of `Set`. The builder still accepts a plain `Set`.
* Registration ceremony now verifies that the returned credential public key
  matches one of the algorithms specified in
  `RelyingParty.preferredPubkeyParams` and can be successfully parsed.

New features:

* Origin matching can now be relaxed via two new `RelyingParty` options:
  * `allowOriginPort` (default `false`): Allow any port number in the origin
  * `allowOriginSubdomain` (default `false`): Allow any subdomain of any origin
    listed in `RelyingParty.origins`
  * See JavaDoc for details and examples.
* The new `AuthenticatorTransport` can now contain any string value as the
  transport identifier, as required in the editor's draft of the L2 spec. See:
  https://github.com/w3c/webauthn/pull/1275
* Added support for RS1 credentials. Registration of RS1 credentials is not
  enabled by default, but can be enabled by setting
  `RelyingParty.preferredPubKeyCredParams` to a list containing
  `PublicKeyCredentialParameters.RS1`.
  * New constant `PublicKeyCredentialParameters.RS1`
  * New constant `COSEAlgorithmIdentifier.RS1`


== Version 1.4.1 ==

Packaging fixes:

* Fixed dependency declarations so API dependencies are correctly propagated as
  compile-time dependencies of dependent projects.
* Fixed Specification-Version release date in webauthn-server-core jar manifest.


== Version 1.4.0 ==

Changes:

* Class `com.yubico.internal.util.WebAuthnCodecs` is no longer public. The
  package `com.yubico.internal.util` was already declared non-public in JavaDoc,
  but this is now also enforced via Java visibility rules.
* Class `com.yubico.webauthn.meta.Specification.SpecificationBuilder` is no
  longer public. It was never intended to be, although this was not documented
  explicitly.
* Default value for `RelyingParty.preferredPubKeyParams` changed from `[ES256,
  RS256]` to `[ES256, EdDSA, RS256]`
* Data classes no longer use `Optional` internally in field types. This should
  not meaningfully affect the public API, but might improve compatibility with
  frameworks that use reflection.

New features:

* Added support for Ed25519 signatures.
* New constants `COSEAlgorithmIdentifier.EdDSA` and
  `PublicKeyCredentialParameters.EdDSA`
* Artifacts are now built reproducibly; fresh builds from source should now be
  verifiable by signature files from Maven Central.

Security fixes:

* Bumped Jackson dependency to version 2.9.9.3 which has patched CVE-2019-12814,
  CVE-2019-14439, CVE-2019-14379


== Version 1.3.0 ==

Security fixes:

* Bumped Jackson dependency to version 2.9.9 which has patched CVE-2019-12086

New features:

* New optional parameter `timeout` added to `StartRegistrationOptions` and
  `StartAssertionOptions`

Bug fixes:

* Fixed polarity error in javadoc for `RelyingParty.allowUntrustedAttestation`


== Version 1.2.0 ==

New features:

* RSA keys are now supported.
* New constructor functions `PublicKeyCredential.parseRegistrationResponseJson` and `.parseAssertionResponseJson`
  * So users don't have to deal with the `TypeReference`s imposed by the generics, unless they want to.

Bug fixes:

* `android-key` attestation statements now don't throw an exception if
  `allowUntrustedAttestation` is set to `true`.
* `tpm` attestation statements now don't throw an exception if
  `allowUntrustedAttestation` is set to `true`.


== Version 1.1.0 ==

Changed behaviours:

* `AssertionExtensionInputsBuilder.appid(Optional<AppId>)` now fails fast if the
  argument is `null`
* `ClientAssertionExtensionOutputsBuilder.appid(Optional<Boolean>)` now fails
  fast if the argument is `null`


New features:

* Public API methods that take `Optional` parameters now come with
  `Optional`-less aliases.


== Version 1.0.1 ==

Bugfixes:

* Registration no longer fails for unimplemented attestation statement formats
  if `allowUnknownAttestation` is set to `true`.
 ** Registration still fails for attestation statement formats not defined in
    the WebAuthn Level 1 spec.


== Version 1.0.0 ==

* Fixed URL in artifact POM
* Improved a few javadoc wordings


== Version 0.8.0 ==

Possibly breaking changes:

* User Presence (UP) is now always required by the spec, not only when UV is not
  required; implementation updated to reflect this.


New features:

* Added support for `android-safetynet` attestation statement format
 ** Thanks to Ren Lin for the contribution, see https://github.com/Yubico/java-webauthn-server/pull/5
* Implementation updated to reflect Proposed Recommendation version of the spec,
  released 2019-01-17

Bug fixes:

* Fixed validation of zero-valued assertion signature counter
 ** Previously, a zero-valued assertion signature counter was always regarded as
    valid. Now, it is only considered valid if the stored signature counter is
    also zero.


== Version 0.7.0 ==

=== `webauthn-server-attestation` ===

* Added attestation metadata for Security Key NFC by Yubico

=== `webauthn-server-core` ===

Breaking changes:

* Deleted parameter `RelyingParty.verifyTypeAttribute`. This was added as a
  workaround while browser implementations were incomplete, and should never be
  used in production.
* Replaced field `RegisteredCredential.publicKey: PublicKey` with
  `publicKeyCose: ByteArray`. This means the library user no longer needs to
  parse the public key before passing it back into the library.
* `RelyingParty.finishAssertion` now throws `InvalidSignatureCountException`
  instead of its supertype `AssertionFailedException` when signature count
  validation is enabled and the received signature count is invalid.

New features:

* New parameter `StartAssertionOptions.userVerification` which is forwarded into
  `PublicKeyCredentialRequestOptions` by `RelyingParty.startAssertion`


== Version 0.6.0 ==

Breaking changes:

* Classes moved from package `com.yubico.webauthn.data` to `com.yubico.webauthn`:
 **  `AssertionRequest`
 **  `AssertionResult`
 **  `RegistrationResult`
* All public classes are now final.
* All builders now enforce mandatory arguments at compile time. Some usages may
  therefore need to adjust the order of calls on the builder instance.
 ** Static method `Attestation.trusted(boolean)` replaced with `.builder()` with
    `.trusted(boolean)` as builder method instead
 ** `AuthenticatorAssertionResponse` constructor is now private.
 ** `AuthenticatorAttestationResponse` constructor is now private.
 ** `PublicKeyCredentialDescriptor` constructor is now private.
 ** `PublicKeyCredentialRequestOptions` constructor is now private.
* All classes that take collections as constructor (builder) arguments now make
  shallow copies of those collections, so that mutations of the collections
  don't propagate into the class instance.
* Deleted interface `Crypto` and constructor parameter `crypto` of `RelyingParty`
* Deleted interface `ChallengeGenerator` and constructor parameter
  `challengeGenerator` of `RelyingParty`
* Updated implementation to agree with current editor's draft of the spec
 ** Renamed class `AttestationData` to `AttestedCredentialData`
 ** Enum constant `TokenBindingStatus.NOT_SUPPORTED` deleted; this is now
    instead signaled by a missing value
 ** Parameter `RelyingParty.allowMissingTokenBinding` therefore removed
 ** Enum constant `AttestationType.PRIVACY_CA` renamed to `ATTESTATION_CA`
* Renamed class `AuthenticationDataFlags` to `AuthenticatorDataFlags`
* Deleted constant `UserVerificationRequirement.DEFAULT`
* Deleted method `AttestationObject.getAuthData()`
* Changed type of field `RelyingParty.origins` from `List` to `Set`
* Fixed (reduced) visibility of `RegisteredCredential` fields
* Class `MetadataObject` moved to `webauthn-server-attestation` module
* Updated and greatly expanded Javadoc

New features:

* Constructor parameter `pubKeyCredParams` of `RelyingParty` is now optional
  with a default value.
* Constructor parameter `origins` of `RelyingParty` is now optional and defaults
  to a list whose only element is the RP ID prefixed with `https://`.
* All classes with a builder now also have a `.toBuilder()` method.


== Version 0.5.0 ==

=== `webauthn-server-core` ===

New features:

* `PackedAttestationStatementVerifier` now supports SHA256WithRSA signatures

Bug fixes:

* `PublicKeyCredentialDescriptor.compareTo` is now consistent with equals
* `AuthenticatorData` constructor should now throw more descriptive exceptions
  instead of raw `ArrayIndexOutOfBoundsException`s


=== `webauthn-server-attestation` ===

Breaking changes:

* Interface `MetadataResolver` replaced with interfaces `AttestationResolver`
  and `TrustResolver`
 ** Class `SimpleResolver` split into `SimpleAttestationResolver` and
    `SimpleTrustResolver`
  *** Both of these classes now take the metadata as a constructor parameter
      instead of exposing `addMetadata` methods
 ** Class `CompositeResolver` split into `CompositeAttestationResolver` and
    `CompositeTrustResolver`
* Class `StandardMetadataService` overhauled


== Version 0.4.0 ==

Breaking changes:

* Field `StartRegistrationOptions.requireResidentKey: boolean` replaced with
  field `authenticatorSelection: Optional<AuthenticatorSelectionCriteria>`


== Version 0.3.0 ==

* Major API overhaul; public API changes include but are not limited to:
 ** Reorganised package structure
 ** `CredentialRepository.getCredentialIdsForUsername(String)` now returns `Set`
    instead of `List`
 ** Most data classes now expose a builder instead of a public constructor
 ** Shortcut constants added to `COSEAlgorithmIdentifier` and
    `PublicKeyCredentialParameters`
 ** Exception `U2fBadConfigurationException` renamed to
    `BadConfigurationException`
 ** `RelyingParty.startRegistration` now accepts one `StartRegistrationOptions`
    parameter instead of several parameters

    `FinishRegistrationOptions` parameter instead of several parameters
 ** `RelyingParty.startAssertion` now accepts one `StartAssertionOptions`
    parameter instead of several parameters
 ** `RelyingParty.finishAssertion` now accepts one `FinishAssertionOptions`
    parameter instead of several parameters
 ** `RelyingParty.finishRegistration` now throws checked
    `RegistrationFailedException` instead of `IllegalArgumentException` on most
    failures
 ** `RelyingParty.finishAssertion` now throws checked
    `AssertionFailedException` instead of `IllegalArgumentException` on most
    failures
 ** Class `MetadataResolver` replaced with interface
 ** Constructor `CollectedClientData(JsonNode)` deleted
 ** Parameters `StartRegistrationOptions.excludeCredentials` and
    `StartAssertionOptions.allowCredentials` deleted; they are now discovered
    automatically from the `CredentialRepository`. If custom control over
    `excludeCredentials` or `allowCredentials` is needed, modify the
    `PublicKeyCredentialCreationOptions` or `PublicKeyCredentialRequestOptions`
    object manually.
 ** `COSEAlgorithmIdentifier` is now an actual enum
 ** Extensions are now passed and returned as domain objects instead of as Jackson
    types
 ** Type parameter added to `PublicKeyCredential` to express extensions type
 ** Fields `CollectedClientData.authenticatorExtensions` and `.clientExtensions`
    deleted

  *** `AttestationObject`, `AuthenticatorData` and `CollectedClientData` now serialize back to
    Base64Url encoded bytes instead of to JSON objects
  *** Member `_attestationObject` removed from serialized
      `AuthenticatorAttestationResponse`

* Too many other changes to count


== Version 0.1.0 ==

* First release of https://www.w3.org/TR/webauthn/[Web Authentication] support

== Version 0.19.0 ==

Breaking changes:

* Overhauled exception hierarchy
 ** New exception class: `U2fCeremonyException`
 ** New exception class: `U2fRegistrationException extends U2fCeremonyException`
 ** New exception class: `U2fAuthenticationException extends U2fCeremonyException`
 ** The following exception classes now extend `U2fAuthenticationException`:
  *** `DeviceCompromisedException`
  *** `InvalidDeviceCounterException`
  *** `NoEligableDevicesException`
  *** `NoEligibleDevicesException`
 ** `U2fBadConfigurationException` is now a checked exception
 ** `U2fBadInputException` is now a checked exception, and is no longer thrown directly by the methods of `U2F`.
