AWS SDK JS Crypto Helpers is a collection of cryptographic helper packages for JavaScript and Node.js, providing simple primitives for browser or Node.js use. It is useful if you need building blocks like cryptographically secure random values, hashing helpers (for example SHA-256), or capability checks (such as web crypto support) while using AWS Crypto Tools.
Project status
- Actively maintained? Repo has a very recent upstream push (2026-08-10), which suggests ongoing activity, but the published updates/tag history in the provided data stops at v5.2.0 (2023-10-16), so release-facing maintenance appears to have been quiet for a long stretch.
- Update cadence (apparent): Updates are clustered in 2023 (v5.0.0 on 2023-07-13, v5.1.0 on 2023-09-22, v5.2.0 on 2023-10-16). After that, the next evidence of updates is not present until the 2026-08-10 upstream push, so cadence is hard to confirm for releases.

Recent updates
v5.2.0
No release notes were provided for v5.2.0 in the publisher metadata. The code diff indicates this release reorganized package build outputs to ship dual artifacts, adding ESM-compatible builds alongside the existing CommonJS builds.
Breakingv5.1.0
Release v5.1.0 updates this crypto helpers monorepo to use @smithy/util-utf8 instead of @aws-sdk/util-utf8-browser, and includes a tooling update (tsc). In addition to dependency changes, the random-source-browser package was refactored to make secure random source detection more testable.
Featuresv5.0.0
The publisher provided release v5.0.0 with no release notes or detailed change log. As a result, there is insufficient information to identify new features, bug fixes, breaking changes, security updates, or required migrations.
v4.0.1
Version v4.0.1 is a small patch release that primarily corrects package naming in the browser field for @aws-crypto/sha256-universal. The diff also includes maintenance-policy documentation updates, and a large package-lock.json churn consistent with dependency-resolution updates.
v4.0.0
No publisher release notes were provided for v4.0.0. The code diff shows this release is primarily a monorepo/package version bump plus CI and release pipeline updates related to Node.js support (notably removing Node 12).
v3.0.0
Release v3.0.0 contains major refactors across the crypto helper packages, but the GitHub release notes section is empty (no documented changes were provided). The code diff shows interface-level changes around hashing/checksumming and added reset support, along with significant dependency upgrades (including a jump in @aws-sdk/types).
Featuresv2.0.2
Release notes were not provided for v2.0.2 (no publisher release notes content available). The diff shows this release is primarily a dependency and package-manifest update across the monorepo, bumping package versions to 2.0.2 and updating tooling and @aws-sdk/types versions.
v2.0.1
v2.0.1 appears to be a small patch release with a bug fix centered on the @aws-crypto/util helper uint32ArrayFrom. The repo also bumps package versions for the workspace (lerna.json and multiple package.json files) and adds a focused unit test for uint32ArrayFrom.
v2.0.0
v2.0.0 was released with no publisher-provided release notes. The diff for this release shows primarily metadata and packaging changes (version bumps, docs/support policy formatting, and a CI publish workflow tweak), with no actual source code changes shown in the provided diff.
v1.2.2
The publisher did not provide any release notes for v1.2.2, so there is no documented information about what changed. Without release notes, developers should review the changelog/diff between v1.2.1 and v1.2.2 (or the GitHub commits for this tag) to identify any potential API, behavior, or dependency changes.
