[bug\_fix] Error: error:0308010C:digital envelope routines::unsupported at new Hash \(internal/crypto/hash.js\)

Set the environment variable NODE\_OPTIONS=--openssl-legacy-provider before running the build command \(e.g., export NODE\_OPTIONS=--openssl-legacy-provider && npm run build on Unix or set NODE\_OPTIONS=--openssl-legacy-provider&&npm run build on Windows\), or upgrade the offending package \(webpack, vite, etc.\) to a version that supports OpenSSL 3.0, or downgrade Node.js to version 16.x \(which uses OpenSSL 1.1.1\). The root cause is that Node.js 17\+ uses OpenSSL 3.0, which has stricter cryptographic algorithms; older versions of webpack \(4.x\) and other build tools use md4 hashes via crypto.createHash, which is unsupported in OpenSSL 3.0 in the default provider.

Journey Context:
You upgrade your local Node.js installation to version 18 \(LTS\) to get new features. You pull your team's legacy React project \(using webpack 4\) and run 'npm start'. Instead of the dev server, you get a cryptic OpenSSL error 'error:0308010C:digital envelope routines::unsupported'. You check the stack trace and it points to internal/crypto/hash.js. You're confused because you didn't change any crypto code. You search the error code and find it relates to Node 17\+ switching to OpenSSL 3.0. You try downgrading Node but that's a hassle for other projects. You find a StackOverflow post suggesting NODE\_OPTIONS=--openssl-legacy-provider. You set it in your terminal and the build works. You realize the old webpack is using an outdated crypto algorithm \(md4\) for hashing. The permanent fix is either upgrading webpack to v5 \(which fixes the crypto usage\) or using the legacy OpenSSL provider flag until you can upgrade. This error is extremely common in CI/CD pipelines that suddenly start using Node 18 images.

environment: Node.js 17.0.0\+ \(especially 18 LTS\), OpenSSL 3.0. Legacy webpack 4.x, older vue-cli, react-scripts < 5. Linux, macOS, Windows all affected. · tags: openssl digital-envelope routines err_ossl_evp_unsupported node_options legacy-provider webpack · source: swarm · provenance: https://nodejs.org/api/cli.html\#--openssl-legacy-provider
