Webpack build failing with ERR_OSSL_EVP_UNSUPPORTED

Question

I'm having an issue with a Webpack build process that suddenly broke, resulting in the following error...

<s> [webpack.Progress] 10% building 0/1 entries 0/0 dependencies 0/0 modules
node:internal/crypto/hash:67
  this[kHandle] = new _Hash(algorithm, xofLen);

}

I've tried googling ERR_OSSL_EVP_UNSUPPORTED webpack which yielded almost no useful results, but it did highlight an issue using MD4 as provided by OpenSSL (which is apparently deprecated?) to generate hashes.

The webpack.config.js code is as follows:

const path = require('path');
const webpack = require('webpack');

/*
 * SplitChunksPlugin is enabled by default and replaced
 * deprecated CommonsChunkPlugin. It automatically identifies modules which
 * should be splitted of chunk by heuristics using module duplication count and
 * module category (i. e. node_modules). And splits the chunks…
 *
 * It is safe to remove "splitChunks" from the generated configuration
 * and was added as an educational example.
 *
 * https://webpack.js.org/plugins/split-chunks-plugin/
 *
 */

/*
 * We've enabled TerserPlugin for you! This minifies your app
 * in order to load faster and run less javascript.
 *
 * https://github.com/webpack-contrib/terser-webpack-plugin
 *
 */

const TerserPlugin = require('terser-webpack-plugin');

module.exports = {
    mode: 'development',
    entry: './src/js/scripts.js',

    output: {
        path: path.resolve(__dirname, 'js'),
        filename: 'scripts.js'
    },

    devtool: 'source-map',

    plugins: [new webpack.ProgressPlugin()],

    module: {
        rules: []
    },

    optimization: {
        minimizer: [new TerserPlugin()],

        splitChunks: {
            cacheGroups: {
                vendors: {
                    priority: -10,
                    test: /[\\/]node_modules[\\/]/
                }
            },

            chunks: 'async',
            minChunks: 1,
            minSize: 30000,
            name: 'true'
        }
    }
};

How do I change the hashing algorithm used by Webpack to something else?

I was able to fix it via:

export NODE_OPTIONS=--openssl-legacy-provider

sachaw's comment to Node.js v17.0.0 - Error starting project in development mode #30078

But they say they fixed it: ijjk's comment to Node.js v17.0.0 - Error starting project in development mode #30078:

Hi, this has been updated in v11.1.3-canary.89 of Next.js, please update and give it a try!

For me, it worked only with the annotation above.

I also want to point out that npm run start works with -openssl-legacy-provider, but npm run dev won't.

It seems that there is a patch: Node.js 17: digital envelope routines::unsupported #14532

I personally downgraded to 16-alpine.

I had this problem too. I'd accidentally been running on the latest Node.js (17.0 at time of writing), not the LTS version (14.18) which I'd meant to install. Downgrading my Node.js install to the LTS version fixed the problem for me.

@Trip check your package.json for ReactNative. Ask a question. – Abhinav Saxena Dec 21 '21 at 08:51
@AbhinavSaxena We do not use React, and ReactNative does not appear anywhere in our package-lock.json. – Trip Dec 21 '21 at 17:11
@Trip Okay, [Note: it's package.json and not package-lock.json] I used this solution for ReactNative and saw that it favoured people using ReactJS (web development) as well, so I was curious. I think you can ask a separate question specifying the platform you are using. – Abhinav Saxena Dec 21 '21 at 17:17

There is a hashing algorithm that comes with Webpack v5.54.0+ that does not rely on OpenSSL.

To use this hash function that relies on a npm-provided dependency instead of an operating system-provided dependency, modify the webpack.config.cjs output key to include the hashFunction: "xxhash64" option.

module.exports = {
    output: {
        hashFunction: "xxhash64"
    }
};

Ryan Brownell's answer is the ideal solution if you are using Webpack v5.54.0+.

If you're using an older version of Webpack, you can still solve this by changing the hash function to one that is not deprecated. (It defaults to the ancient md4, which OpenSSL has removed support for, which is the root cause of the error.) The supported algorithms are any supported by crypto.createHash. For example, to use SHA-256:

module.exports = {
    output: {
        hashFunction: "sha256"
    }
};

Finally, if you are unable to change the Webpack configuration (e.g., if it's a transitive dependency which is running Webpack), you can enable OpenSSL's legacy provider to temporarily enable MD4 during the Webpack build. This is a last resort. Create a file openssl.cnf with this content…

openssl_conf = openssl_init

[openssl_init]
providers = provider_sect

[provider_sect]
default = default_sect
legacy = legacy_sect

[default_sect]
activate = 1

[legacy_sect]
activate = 1

…and then set the environment variable OPENSSL_CONF to the path to that file when running Webpack.

Turns out that the `hashFunction` fix can help. but it might be insufficient: the ConcatenatedModule optimizer in Webpack 4.x [hardcodes the use of MD4](https://github.com/webpack/webpack/blob/3956274f1eada621e105208dcab4608883cdfdb2/lib/optimize/ConcatenatedModule.js#L563), so if your build process uses it, you might need to go the `openssl.cnf` route. I think this might be the general case for Vue CLI 4.x projects. — Peter, Oct 21 '21 at 15:23

It is not my answer really, but I found this workaround /hack/ to fix my problem Code Check in for a GitHub project... see the bug comments here.

I ran into ERR_OSSL_EVP_UNSUPPORTED after updating with npm install.

I added the following to node_modules\react-scripts\config\webpack.config.js

const crypto = require("crypto");
const crypto_orig_createHash = crypto.createHash;
crypto.createHash = algorithm => crypto_orig_createHash(algorithm == "md4" ? "sha256" : algorithm);

I tried Ryan Brownell's solution and ended up with a different error, but this worked...

This worked fine for me in Webpack4. I'm bouncing between 12LTS / 17 and this is a big time saver. – Daniel B. Chapman Oct 23 '21 at 23:34
This should be the accepted answer in 2021. Thank you for describing the folder location of the file as well. It solved my issue. I had previously tried the solution that exports variables to the environment and it caused VSCode to no longer load. So this solves it without globally compromising other programs. – Terry Nov 05 '21 at 15:57

This error is mentioned in the release notes for Node.js 17.0.0, with a suggested workaround:

If you hit an ERR_OSSL_EVP_UNSUPPORTED error in your application with Node.js 17, it’s likely that your application or a module you’re using is attempting to use an algorithm or key size which is no longer allowed by default with OpenSSL 3.0. A command-line option, --openssl-legacy-provider, has been added to revert to the legacy provider as a temporary workaround for these tightened restrictions.

I ran into this issue using Laravel Mix (Webpack) and was able to fix it within file package.json by adding in the NODE_OPTIONS=--openssl-legacy-provider (referenced in Jan's answer) to the beginning of the script:

package.json:

{
  "private": true,
  "scripts": {
    "production": "cross-env NODE_ENV=production NODE_OPTIONS=--openssl-legacy-provider  node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
  },
  "dependencies": {
    ...
  }
}

I had the same problem with my Vue.js project and I solved it.

You should have installed NVM (Node Version Manager). If you never had before, just run this command in your terminal:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash

Open your project
Open the terminal in your project
Run the command nvm install 16.13.0 or any older version
After the installation is completed, run nvm use 16.13.0

This means that you have the latest Node.js version. If you are using it for Docker then you need to change the image from

FROM node

to
