Hash Permalink

Description

Hash Permalink is a lightweight, high-performance WordPress plugin that automatically replaces default post slugs with random hash-based short URLs when new content is published.

Why Use Hash Permalinks?

  • Privacy & Security — Hash URLs prevent content scraping and hide your publishing patterns.
  • Clean & Professional — Short, random URLs look modern and trustworthy.
  • SEO Safe — Only applies to new posts; existing URLs are never modified.
  • Flexible — Customize hash length, character set, prefixes, and which post types to apply.

Key Features

  • Auto Hash Generation — Seamlessly generates unique hash slugs using cryptographically secure random numbers.
  • Collision Prevention — Database-level uniqueness check with automatic retry.
  • Multiple Character Sets — Choose from numeric, lowercase alphanumeric, mixed case, or hexadecimal.
  • Configurable Length — Select 8, 12, or 16 character hashes.
  • Post Type Support — Works with Posts, Pages, and any registered Custom Post Type.
  • Custom Prefix & Suffix — Add optional URL prefixes or suffixes.
  • Settings Page — Intuitive admin settings page under Settings menu.

Example URLs

  • https://yoursite.com/a7k2m9x4b1n3 (lowercase alphanumeric, 12 chars)
  • https://yoursite.com/6031e781c304 (hexadecimal, 12 chars)
  • https://yoursite.com/post-a7k2m9x4 (with “post” prefix, 8 chars)
  • https://yoursite.com/839201748362 (numeric, 12 chars)

FAQ

Will this plugin modify existing post URLs?

No. The plugin only intercepts the saving process for new posts or posts that have their slug manually cleared. Existing URLs are safe and will not be altered.

What happens if I uninstall the plugin?

The hash URLs generated while the plugin was active are permanently saved to the WordPress database as native post slugs. Uninstalling the plugin will not break your existing links.
