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

Set the environment variable NODE\_OPTIONS to --openssl-legacy-provider. On Unix: export NODE\_OPTIONS=--openssl-legacy-provider. On Windows PowerShell: $env:NODE\_OPTIONS='--openssl-legacy-provider'. On Windows CMD: set NODE\_OPTIONS=--openssl-legacy-provider. Then run your build command. Alternatively, upgrade webpack to version 5.61.0 or higher, or upgrade react-scripts to version 5\+, which include fixes for OpenSSL 3.0 compatibility. The root cause is that Node.js 17 and higher use OpenSSL 3.0, which has stricter cryptographic algorithms and disables legacy digest methods \(like MD4 used by older webpack\) by default, causing crypto.createHash to fail.

Journey Context:
You upgrade to Node.js 17, 18, or 20, and suddenly your Create React App or Next.js build fails with a cryptic 'error:0308010C:digital envelope routines::unsupported' or 'ERR\_OSSL\_EVP\_UNSUPPORTED'. The error appears during the webpack compilation phase. You search online and find conflicting advice about downgrading Node. You check the Node 17 release notes and see OpenSSL 3.0 was added. You realize old webpack 4 uses crypto.createHash with algorithms that OpenSSL 3.0 disables by default. You try setting NODE\_OPTIONS=--openssl-legacy-provider before your build command, which tells Node to enable the legacy OpenSSL provider, restoring the old behavior and allowing the build to complete. You later upgrade webpack to v5, which properly handles OpenSSL 3.0, removing the need for the flag.
