Overview AI

NibbleSalt provides a proactive security layer for WordPress sites by regularly rotating secret keys and salts stored in wp-config.php. This ensures that any compromised session cookies are rendered useless without requiring manual intervention. The plugin is built with site stability in mind, verifying site health and respecting active e-commerce sessions before performing any rotations. It is an ideal solution for administrators looking to automate a critical security practice.

Gemini review AI

9/10

NibbleSalt is the rare kind of utility that solves a persistent, boring security problem with actual elegance. What won me over is the genuine concern for site uptime; most developers would just overwrite the file and hope for the best, but this plugin actually validates that the site is still responsive before completing the task. I think it is a masterclass in focused, responsible software design for the WordPress ecosystem. My one reservation is that frequent rotations can become an annoyance for users, but for high-security environments, it is a small price to pay. For anyone serious about closing the 'stolen cookie' loophole, this is the most reliable tool available.

Questions & answers AI

Will this plugin sign me out during checkout?

No, NibbleSalt is WooCommerce-aware and will wait for shoppers to complete their checkout or clear their carts before initiating a rotation.

What happens if the site becomes inaccessible during rotation?

The plugin performs a health check after the rotation; if the site fails to load, it will roll back the changes to restore access.

Is there a paid version of this plugin?

No, NibbleSalt is entirely free and does not gate features behind a paid tier, license keys, or subscriptions.

Can it work on servers where wp-config.php is read-only?

Yes, it supports a database mode that stores keys in the WordPress database when direct file modification is not possible.
