Report #100069

[bug\_fix] Error: error:0308010C:digital envelope routines::unsupported \(ERR\_OSSL\_EVP\_UNSUPPORTED\)

Upgrade your build tooling to a version compatible with OpenSSL 3 \(webpack 5.61.0\+, Next.js 12.0.9\+, Vite 3\+, etc.\). The short-term workaround is \`NODE\_OPTIONS=--openssl-legacy-provider\` before the build command, or adding \`"scripts": \{ "build": "NODE\_OPTIONS=--openssl-legacy-provider next build" \}\`. The flag re-enables the legacy OpenSSL provider that Node disabled by default.

Journey Context:
You install Node 18 on a new laptop, clone a project from 2021, and \`npm run build\` dies inside webpack's crypto usage with \`ERR\_OSSL\_EVP\_UNSUPPORTED\`. You downgrade to Node 16 and it works, but you need Node 18 for another project. You trace the stack to \`crypto.createHash\` inside webpack. Node 17\+ ships OpenSSL 3, which changed the default hash algorithms and broke older webpack MD4 usage. The permanent fix is upgrading webpack; the legacy-provider flag is the documented stopgap that restores the old OpenSSL algorithms for older toolchains.

environment: Node 17\+ / OpenSSL 3 with old webpack, Next.js, Vue CLI, or React Scripts projects. · tags: openssl err_ossl_evp_unsupported webpack nextjs node18 legacy-provider · source: swarm · provenance: https://nodejs.org/api/cli.html\#node\_options
