I Built the Same Hash Utility for Browser, Node, and Python

Hashing text is easy until you try to make the same workflow feel clean across different environments.

In the browser, you usually reach for the Web Crypto API. For files, that means working with File or Blob objects and reading them as ArrayBuffer.

In Node, file hashing usually means streams and the built-in crypto module.

In Python, the same job usually goes through hashlib.

None of that is complicated on its own. The annoying part is that the APIs are different enough that you end up rewriting the same small helpers over and over.
