Redirect to:

This page is a redirect. The following categories are used to track and monitor this redirect:

With history: This is a redirect from a page containing substantive page history. This page is kept as a redirect to preserve its former content and attributions. Please do not remove the tag that generates this text (unless the need to recreate content on this page has been demonstrated), nor delete this page.
- This template should not be used for redirects having some edit history but no meaningful content in their previous versions, nor for redirects created as a result of a page merge (use {{R from merge}} instead), nor for redirects from a title that forms a historic part of Wikipedia (use {{R with old history}} instead).

To a related topic: This is a redirect to an article about a similar topic.
- Redirects from related topics are different than redirects from related words, because a related topic is more likely to warrant a full and detailed description in the target article. If this redirect's subject is notable, then also tag it with {{R with possibilities}} and {{R printworthy}}.

From an avoided double redirect: This is a redirect from an alternative title or related topic of Hash valueHash value, another redirect to the same title. Because double redirects are disallowed, both pages currently point to Hash function.
- If Hash valueHash value is retargeted or is expanded into a separate article, template, or other project page, this redirect will be recategorized to be updated.

When appropriate, protection levels are automatically sensed, described and categorized.
