Fedify's public declarations used the ambient CryptoKey and CryptoKeyPair types, so the consumer's lib setting decided which declaration those names resolved to. Since @types/node 24.7.0, Node.js's webcrypto.KeyUsage includes the ML-KEM usages, which makes its usage array incompatible with the DOM/Web Worker one. Applications could not pass keys from node:crypto to Fedify.

Casting inside Fedify cannot fix an error at the caller's assignment, so the input positions now accept the structural CryptoKeyLike and CryptoKeyPairLike types from packages/vocab-runtime/src/crypto-key.ts. Keys returned by Fedify keep the ambient types, so they still pass to crypto.subtle.* without a cast. ActorKeyPairsDispatcher gained an optional key pair type parameter that defaults to CryptoKeyPair, so code calling a dispatcher directly keeps its narrow return type.

Fixes #554.

Changes

  • Widened the input positions of the key pairs dispatchers, SenderKeyPair, the signing and proof helpers, exportJwk(), the authenticated document loader identity, and the key export helpers in @fedify/vocab-runtime.
  • Widened only the publicKey inputs of CryptographicKey and Multikey in the generator, keeping the getters narrow.
  • Added a type-level regression test in packages/fedify/src/sig/key-types.test.ts that mimics the wider Node.js usage union, because the repository's own type check uses the Web Worker lib and cannot reproduce the failure.
  • Added changelog fragments for the affected packages.

Benefits

Applications on Node.js can pass Web Crypto keys from node:crypto directly, without as CryptoKey casts. The change is source-compatible except for implementations of AuthenticatedDocumentLoaderFactory that annotate the identity parameter with the ambient type, which now need CryptoKeyLike.

Walkthrough

Fedify adds structural Web Crypto key types for key inputs across runtime, federation, signing, and vocabulary APIs. Key operations convert compatible keys before Web Crypto calls. Vocabulary generation uses CryptoKeyLike for key inputs while preserving ambient CryptoKey getter types.

Changes: Web Crypto key compatibility

Layer / File(s) Summary
Structural key contracts and adapters
packages/vocab-runtime/src/crypto-key.ts, packages/vocab-runtime/src/{internal,jwk,key,mod}.ts, changes.d/vocab-runtime/*, CHANGES.md
vocab-runtime defines and exports CryptoKeyLike and CryptoKeyPairLike. JWK, SPKI, and multibase export APIs accept structural keys and convert them before Web Crypto exports.
Fedify key API integration
packages/fedify/src/federation/*, packages/fedify/src/sig/*, packages/fedify/src/utils/docloader.ts, changes.d/fedify/*, CHANGES.md
Federation dispatchers, sender key pairs, signing helpers, and authenticated document-loader APIs accept structural key types. Signing and key-loading paths convert keys before passing them to Web Crypto or authenticated loaders. Compile-time checks cover Node.js key shapes.
Vocabulary key input generation
packages/vocab-tools/src/{class,constructor,type}.ts, packages/vocab/scripts/codegen.ts, changes.d/vocab/*, changes.d/vocab-tools/*, CHANGES.md
Generated constructor and clone() inputs use CryptoKeyLike for the public-key and multibase-key scalars. Code-generation freshness checks include generator sources and metadata.

Trivial · Maintainability & Code Quality · Quick win

Add compile-time assertions for the clone inputs of CryptographicKey and Multikey.

The compile-time checks cover only the constructor publicKey parameters. The generated clone methods also accept publicKey?: CryptoKeyLike | null, but no assertion checks them. A regression in the clone signature would pass the current checks. The first clone parameter defaults to {}, so it includes undefined. Unwrap it before indexing publicKey.

Addressed the outside-diff clone assertion from #1391 (review) in 22677c2. packages/fedify/src/sig/key-types.test.ts now checks the generated clone() inputs of CryptographicKey and Multikey against the wider Node.js key type.

The docstring coverage check still reports a failure. The functions this PR adds or changes are documented; the remaining count comes from pre-existing undocumented helpers in the generator files, so repo-wide docstring coverage is outside this PR.

The SharedInboxKeyDispatcher case from #1391 (review) is covered in 06bbb1d as well. The dispatcher now takes a key type parameter that defaults to CryptoKey, so reading its result keeps the ambient type, while setSharedKeyDispatcher() accepts a dispatcher that returns SenderKeyPair<CryptoKeyLike>.

The codegen freshness check compared vocab.ts only against the YAML
schemas, so an existing checkout kept the old generated code after a
change to the vocabulary generator.  Compare it against the generator
sources under packages/vocab-tools/src as well.

CodeRabbit's docstring coverage check flagged the changed generator
files, so add the missing docstrings to the helper that builds the
constructor parameter types and to the type name resolvers.

The generated code embeds the @fedify/vocab-tools version from its
deno.json in tracing calls, so a version bump alone must invalidate
vocab.ts.  Include the generator metadata in the freshness check.

The compile-time checks covered only the constructor publicKey

Widening SenderKeyPair.privateKey and the authenticated document loader
identity broke code that reads those values and passes them to Web
Crypto.  Give SenderKeyPair and SharedInboxKeyDispatcher a key type
parameter that defaults to CryptoKey, and keep the document loader
factory on the ambient type.  Fedify still accepts node:crypto keys at
its input boundaries and narrows them internally.

Fedify's public declarations referred to the ambient `CryptoKey` and
`CryptoKeyPair` types, so the consumer's `lib` setting decided which
declaration those names resolved to.  Since `@types/node` 24.7.0,
Node.js's `webcrypto.KeyUsage` includes the ML-KEM usages, which makes
its usage array incompatible with the DOM and Web Worker one.
Applications could not pass keys obtained from `node:crypto` to
Fedify.

Input positions now accept the structural `CryptoKeyLike` and
`CryptoKeyPairLike` types added to `@fedify/vocab-runtime`, while the
keys Fedify returns keep the ambient types.  `ActorKeyPairsDispatcher`
takes an optional key pair type parameter that defaults to
`CryptoKeyPair`, so code calling a dispatcher directly keeps its narrow
return type.  The vocabulary code generator uses the wider type for
constructor and `clone()` inputs, and the getters stay narrow.

The repository's own type check cannot reproduce the failure because it
uses the Web Worker lib and never passes `node:crypto` keys into the
API, so a type-level regression test mimics the wider Node.js usage
union.
