Report #53196

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

Set environment variable NODE\_OPTIONS=--openssl-legacy-provider or upgrade to webpack 5.61.0\+ / react-scripts 5\+ that support OpenSSL 3.0 natively.

Journey Context:
Developer upgrades from Node 16 LTS to Node 18 LTS and runs npm start on an existing Create React App or Next.js project. The build immediately crashes with 'error:0308010C:digital envelope routines::unsupported'. Initially blames corrupted node\_modules and deletes/reinstalls to no avail. Research reveals Node 17\+ bundles OpenSSL 3.0, which changed EVP\_PKEY behavior, breaking crypto.createHash in old webpack. The legacy provider flag temporarily restores the OpenSSL 1.1.1 algorithm set, allowing the build to complete while the team upgrades their build toolchain.

environment: Node.js 17.0.0\+ \(including 18 LTS, 20 LTS\) on macOS/Linux/Windows; projects using webpack 4, old react-scripts, or any tool using crypto.createHash without specifying algorithm digest. · tags: openssl webpack node18 legacy-provider err_ossl_evp_unsupported crypto · source: swarm · provenance: https://github.com/webpack/webpack/issues/14532 and https://nodejs.org/en/blog/release/v17.0.0\#openssl-3-0
