If you are running Webpack or a CLI tool that’s built on top of Webpack (e.g., react-scripts for Create React App applications or vue-cli-service for Vue applications) with version 17 of Node.js, then you may have come across the following error: With Node.js v17+ supporting OpenSSL 3.0 , algorithms like MD4 have been relegated to OpenSSL 3.0’s legacy provider. A provider is a collection of cryptographic algorithm implementations. OpenSSL 3.0 comes with five standard providers : default, legacy, FIPS, base and null. The legacy provider consists of algorithms that are considered to be rarely used in today’s world or unsafe security-wise. This provider exists for backwards compatibility purposes (for software that still rely on these algorithms) and is not loaded by default. Webpack creates hashes using the crypto.createHash() method of the Node.js crypto module. This method can only create hashes with algorithms that are available and supported by the version of OpenSSL corresponding to the currently installed Node.js version. Since Webpack specifies to the crypto.createHash() method to use the MD4 algorithm (see below code), and this algorithm is not readily available in Node.js v17+ due to OpenSSL 3.0 not loading legacy providers by default, Webpack errors out and Node.js logs the error message Error: error:0308010C:digital envelope routines::unsupported .

Web development is tough enough as it is, something as mundane as mismatched versions of Node in development versus production shouldn't be another thing you have to keep in mind. Volta can prevent this sort of issue and so much more for you and your dev team automatically, and it's easy to set up to boot. Read on to get started using it yourself.
