+/**
+ * Webpack 4 uses md4 internally because it is fast.
+ * Some loaders also use md5 directly.
+ * It is not available systems with FIPS enabled node.
+ *
+ * This is a hack to monkey patch the crypto function to use
+ * another algorithm if md4 or md5 is expected.
+ *
+ * https://github.com/webpack/webpack/issues/13572#issuecomment-923736472
+ *
+ * This hack can be removed once we upgrade to webpack v5 as
+ * it includes native support for configuring hash options:
+ * https://github.com/webpack/webpack/pull/14306
