@arcjet/stable-hash

[Arcjet][arcjet] stable hashing utility.

- npm package (@arcjet/stable-hash)
- GitHub source code (stable-hash/ in arcjet/arcjet-js)

What is this?

This is an internal utility to help us create stable hashes.
It’s super minimal and matches similar internal code in other languages.
This exists to make sure things work the same across languages.

When should I use this?

This is an internal Arcjet package not designed for public use.
See our [_Get started_ guide][arcjet-get-started] for how to use Arcjet in your
application.
