Report #52615

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

Set environment variable \`NODE\_OPTIONS=--openssl-legacy-provider\` \(e.g., \`export NODE\_OPTIONS=--openssl-legacy-provider\` in Unix or \`set\` in Windows\), or upgrade build tools \(webpack 5, vite\) to versions supporting OpenSSL 3.0, or use Node.js 16 LTS.

Journey Context:
Developer upgrades to Node.js 17\+ \(or uses a fresh install on Apple Silicon/Windows\). Running \`npm start\` on a Create React App or webpack 4 project throws 'error:0308010C:digital envelope routines::unsupported'. Developer searches and finds Node 17 upgraded to OpenSSL 3.0, which changed default hash algorithms. Older webpack versions use MD4 via crypto.createHash, which OpenSSL 3.0 disables. The rabbit hole involves trying to reinstall node\_modules, checking OpenSSL versions. The fix \`NODE\_OPTIONS=--openssl-legacy-provider\` works by enabling the OpenSSL legacy provider in Node's crypto module, restoring the disabled algorithms temporarily. This allows the old webpack to function while the developer upgrades their build chain to versions compatible with OpenSSL 3.0 natively.
