* 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.

* This hack can be removed once we upgrade to webpack v5 as
