[bug\_fix] error:0308010C:digital envelope routines::unsupported

Set NODE\_OPTIONS=--openssl-legacy-provider \(e.g., export NODE\_OPTIONS=--openssl-legacy-provider in Linux/Mac or set in Windows\), or upgrade webpack to v5.61.0\+ / react-scripts to 5.0.1\+ / vue-cli to v5\+, or downgrade to Node.js 16 LTS. Root cause: Node.js 17\+ uses OpenSSL 3.0 which disables legacy cryptographic algorithms by default; old webpack 4 and build tools use md4 hash which is unsupported.

Journey Context:
Installed Node.js 18 LTS on a new machine, cloned an existing React project using react-scripts 4, ran npm start, got cryptic OpenSSL error:0308010C. Thought Node was corrupted. Reinstalled, same issue. Googled error code, found Node 17 release notes explaining OpenSSL 3.0 upgrade. Discovered the --openssl-legacy-provider flag. Added NODE\_OPTIONS=--openssl-legacy-provider to .env file, which fixed it temporarily. Then upgraded react-scripts to version 5.0.1 which includes webpack 5 with OpenSSL 3.0 compatible hash functions, allowing removal of the legacy flag.

environment: Node.js 17, 18, 19, 20 with webpack 4, react-scripts <5, vue-cli <5, or old native crypto usage · tags: openssl node-17 error:0308010c digital-envelope webpack react-scripts legacy-provider · source: swarm · provenance: https://nodejs.org/en/blog/release/v17.0.0\#openssl-3.0
