A Node.js library that converts ECDSA signatures between JOSE and ASN.1/DER (DER) encodings. It provides functions to translate DER to JOSE-style concatenated signatures and back, targeting algorithms ES256, ES384, and ES512.
Project status
- Maintenance status: The latest described updates are from 2019-01-25 (v1.0.11), with no evidence of recent versioned changes since then, which suggests the package is largely quiet / maintenance mode. However, a recent upstream push on 2026-07-07 indicates there may be ongoing work, even though it is not reflected in new published update entries here.
- Update cadence: The visible update history shows very long gaps between versioned updates (2016-12, 2018-05, 2019-01), so the practical release/update cadence appears infrequent relative to today (2026-08-12).

Recent updates
v1.0.11
Release v1.0.11 contains no release notes from the publisher. The code diff shows no JavaScript logic changes, but it adds new TypeScript declaration files and updates CI (Travis) Node versions, plus a small package.json metadata change to ship typings.
Featuresv1.0.10
v1.0.10 contains a small internal refactor to how base64url encoding is performed in src/ecdsa-sig-formatter.js, removing the runtime dependency on the base64url package. It also updates the fuzz testing setup to generate EC keys using native-crypto instead of elliptic, removing the old fuzz/keygen helper.
v1.0.9
Release v1.0.9 was published on 2016-12-05, but the publisher did not provide release notes. Because no changelog content is available, it is not possible to identify specific new features, breaking changes, bug fixes, or dependency updates from the provided data alone.
