/**
* 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
