Report #30453

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

The root cause is that Node.js 17\+ bundles OpenSSL 3.0, which disables legacy cryptographic algorithms by default. Older versions of webpack \(4.x\) and other tools using crypto.createHash trigger this error. The fix is to either: 1\) Upgrade webpack to version 5.61.0\+ which properly supports OpenSSL 3.0, or 2\) Set the environment variable NODE\_OPTIONS=--openssl-legacy-provider to re-enable legacy algorithms, or 3\) Downgrade to Node.js 16 LTS which uses OpenSSL 1.1.1.

Journey Context:
You upgrade to Node.js 18 LTS and try to start your existing React app created with create-react-app 4.x. Instead of starting, you get 'Error: error:0308010C:digital envelope routines::unsupported' with code ERR\_OSSL\_EVP\_UNSUPPORTED. The error originates from webpack's crypto usage. You search the error and find Node.js 17 changelog mentioning OpenSSL 3.0. You try adding NODE\_OPTIONS=--openssl-legacy-provider to your start script in package.json: 'start': 'NODE\_OPTIONS=--openssl-legacy-provider react-scripts start'. On Windows this requires cross-env or setting it in the shell. It works immediately. However, you read that this is a temporary workaround. You check webpack versions and see you're on 4.46.0. You attempt to upgrade to webpack 5, but create-react-app 4 doesn't support it. You realize the proper fix is either ejecting and upgrading webpack to 5.61\+, or upgrading to create-react-app 5\+ which supports webpack 5 and thus OpenSSL 3.0 natively without the flag.
