I see that we have the following to add a unique ID to any page that is based on a Markdown file:

```markdown
{{ with .File }}
  {{ .UniqueID }}
{{ end }}

```

Is there something comparable for non-file-based pages or is it “ok” to “just” MD5 a bunch of parameters like this:

```markdown
{{ $unique := printf "%s%s%s" .Kind .Section .Slug }}
{{ md5 $unique }}

```

I am only worried about the performance of this solution, not if people might call me a script kiddie 😉 will it slow down on large sites?

Within a given language (site) the `.Page.Path` value is unique, and the page does not have to be backed by a file (v0.123.0 and later). If you want a _globally_ unique ID add `.Page.Language.Lang`. Then pass it through [`crypto.FNV32a`](https://gohugo.io/functions/crypto/fnv32a/) to get something short. Something like:

```plaintext
{{ $uid := printf "%s/%s" .Language.Lang .Path | crypto.FNV32a }}

```
