TLS Inspector is a free & open-source iOS app that enables you to inspect, analyze, and troubleshoot TLS connections.  

**[Learn More about TLS Inspector »](https://tlsinspector.com/)**



## Project Structure

This is the Git repository for the TLS Inspector application. The code of the app and its associated extension are structured into subdirectories:

- `tls-inspector/` - This directory contains code and user interface that is specific to the app itself, for example the input view, recent inspections, about and option view.

- `inspect-website/` - This directory contains a minimal set of code for the show certificate share extension.

- `tlsui/` - This directory contains nearly all of the user interface and supporting systems for it. As the user interface for the app is shared between both the app and the extension, a local swift package is used.

- `tlskit/` - This directory contains all of the logic that performs TLS connection and certificate inspection.

This project also depends on [DNSKit](https://github.com/dns-inspector/dnskit), [external pre-compiled copies of libcurl and openssl](https://github.com/tls-inspector/tlskit-external-dependencies), [root CA certificate bundles](https://github.com/tls-inspector/rootca), and [lists of certificate transparancy logs](https://github.com/google/certificate-transparency-community-site/blob/master/docs/google/known-logs.md).

## Building

Please see [BUILDING](https://github.com/tls-inspector/tls-inspector/blob/app-store/BUILDING.md) for information on how to build TLS Inspector yourself.
