50733628 - fix(ext/node): implement KeyObject.equals, fix createCipheriv with KeyObject/null IV (#32409)

fix(ext/node): implement KeyObject.equals, fix createCipheriv with KeyObject/null IV (#32409) ## Summary Builds on top of #32267 (must be merged first). Implements `KeyObject.prototype.equals()` and fixes `createCipheriv`/`createDecipheriv` to accept `KeyObject` keys and `null` IVs. Closes #27211 Closes #27295 Closes #28405 ## What changed ### `KeyObject.prototype.equals` (new) - Added `PartialEq` implementations for all key types in the Rust layer (`EcPublicKey`, `EcPrivateKey`, `RsaPssPublicKey`, `RsaPssPrivateKey`, `DhPublicKey`, `DhPrivateKey`, `AsymmetricPublicKey`, `AsymmetricPrivateKey`, `KeyObjectHandle`) - Added `op_node_key_equals` op that compares two `KeyObjectHandle` cppgc references - Wired up the JS `equals()` method to call the new op instead of throwing `ERR_NOT_IMPLEMENTED` ### `createCipheriv` / `createDecipheriv` fixes - `toU8()` in cipher.ts now handles `KeyObject` inputs by extracting secret key bytes via `op_node_export_secret_key` - `toU8()` now handles `null` IV (used by ECB mode) by converting to an empty `Uint8Array` - This fixes the `@aws-crypto/client-node` crash reported in #28405 ### Other fixes - `symmetricKeySize` now returns **bytes** instead of bits, matching Node.js behavior - `symmetricKeySize` returns `undefined` for asymmetric keys instead of throwing `notImplemented` - `KeyObject` constructor now validates the `handle` argument type --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
