TLS Inspector

About this app

Trust & Safety in the palm of your hand. • Input & Inspect. It's really that simple. Input a domain or IP address using the TLS Inspector app, or inspect any website from within your favourite browser using our Inspect Website extension. • No Nonsense Results. "At a glance" has never been easier. TLS Inspector will show you the entire issue chain for any website, and whether or not your device trusts that chain. • Dive Deep. Details for days. View important properties of any TLS certificate including fingerprints, dates, algorithms, and more. • Stay Safe Online. No training required. TLS Inspector makes it easy to detect and avoid man-in-the-middle attacks on unsafe networks by highlighting invalid and untrustworthy certificates. • Right Place, Right Time. Inspect nearly anything from anywhere. Easily access TLS Inspector from other apps, such as Safari, with the Show Certificates share sheet action. TLS Inspector is free & libre open source software (FLOSS) with source code available on GitHub. TLS Inspector is made entirely without the use of Artificial Intelligence (AI) or Large Language Models (LLMs).

Thanks for using TLS Inspector! In this update: • Re-added the ability to copy certificate thumbprints • Improved the German localization
