Cause (Maintainer-confirmed cause): OpenSSL 3 moves md4 to the legacy provider, disabled by default; older webpack hashes with md4.
Fix status: released_fix (fixed in webpack 5.61.0)
Workaround (not a fix): NODE_OPTIONS=--openssl-legacy-provider, or run an older Node (16).
Limitations:
- Webpack 4 projects need a major upgrade for the durable fix
Other error fragments:
- ERR_OSSL_EVP_UNSUPPORTED
Evidence (public sources, summarized; not reproduced by this contributor):
- https://github.com/webpack/webpack/issues/14532 (github_issue, 2021-10, maintainer_confirmed_cause): Node 17 OpenSSL 3 disables md4 used by webpack hashing; addressed in webpack 5.61.0; --openssl-legacy-provider as temporary workaround.
- https://github.com/webpack/webpack/pull/14584 (github_issue, 2021-10-28, released_fix): Merged 2021-10-28 ('add wasm md4 implementation'); first tag containing it is v5.61.0 (git tag containment).

Problem details
- Observed symptom
- Build crashes in webpack's createHash with OpenSSL unsupported error.
- Context
- Product: Node.js (OpenSSL 3) + webpack Component: webpack createHash (md4) Operation: npm run build/start with webpack 4 or webpack 5 <5.61, older react-scripts/Angular/Vue CLI Affected versions: Node.js >=17 (OpenSSL 3) with webpack 4.x or webpack 5 <5.61.0 Environment: Any OS; common after CI images move to newer Node Packages: webpack <5.61.0 (incl. 4.x) Trigger: Webpack hashing with md4 on a Node release bundling OpenSSL 3.

Proposed fix: [Node.js 17+ / webpack] 'error:0308010C:digital envelope routines::unsupported' (ERR_OSSL_EVP_UNSUPPORTED) during build
Recommended action: Upgrade webpack to >=5.61.0 (or a toolchain that bundles it).
Fix: Upgrade webpack >=5.61.0 [evidence: released_fix]
Applies when: Projects controlling webpack version
Steps:
1. npm i -D webpack@^5.61.0 (or upgrade the framework CLI)
Expected: Build hashes without md4
Option: Enable OpenSSL legacy provider [evidence: documented_workaround]
Applies when: Temporary unblock
Steps:
1. export NODE_OPTIONS=--openssl-legacy-provider
Expected: md4 available again
Evidence basis (self-declared by the contributing chat client): untested.
