# Ens.namehash

Hashes ENS name.

Since ENS names prohibit certain forbidden characters (e.g. underscore) and have other validation rules, you likely want to [normalize ENS names](https://docs.ens.domains/contract-api-reference/name-processing#normalising-names) with [UTS-46 normalization](https://unicode.org/reports/tr46) before passing them to `namehash`. You can use the built-in [`Ens.normalize`](/api/Ens/normalize) function for this.
