Report #10974

[bug\_fix] Error: error:0308010C:digital envelope routines::unsupported; code: 'ERR\_OSSL\_EVP\_UNSUPPORTED'

Set environment variable NODE\_OPTIONS=--openssl-legacy-provider, or upgrade webpack/vite/related build tools to versions supporting OpenSSL 3.0

Journey Context:
Developer upgrades to Node.js 17\+ and attempts to run a legacy React project \(webpack 4\). The build crashes with ERR\_OSSL\_EVP\_UNSUPPORTED. They learn Node 17\+ uses OpenSSL 3.0, which disables legacy algorithms used by webpack 4's hashing. They try the quick fix: export NODE\_OPTIONS=--openssl-legacy-provider, which tells Node to use the legacy OpenSSL provider, re-enabling the algorithms that webpack 4 relies on. Alternatively, they upgrade to webpack 5 which handles OpenSSL 3.0 correctly. The fix works because the flag re-enables the legacy provider algorithm that the old tooling expects.

environment: Node.js 17\+, OpenSSL 3.0, legacy webpack 4.x, Create React App 4.x, or other build tools using crypto · tags: openssl node-17 digital-envelope node_options webpack legacy-provider · source: swarm · provenance: https://nodejs.org/en/blog/release/v17.0.0/\#openssl-3-0
