Split the hash generation process

[Korko]

Hi,

I'd like to propose a change:

• Create a new method Sti::generateHash(string $content) to generate a hash of a raw content. Can be useful to generate hash for an inline javascript.

I hope you'll find it interesting.

Thanks for the PR, but I'm going to close it.

Subresource Integrity is only useful when fetching files. It let the browser check that the files it's fetching aren't messed with. Per MDN:

Subresource Integrity (SRI) is a security feature that enables browsers to verify that files they fetch (for example, from a CDN) are delivered without unexpected manipulation. It works by allowing you to provide a cryptographic hash that a fetched file must match.

In the context of inline scripts SRI are not useful.
