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.

Its That End User Again ,

🔏Must Have essential security aid for iOS (UPDATE)

I downloaded This tool years ago and it’s been on all my devices- testing and personal- as an essential web tool, especially these days with web apps being everywhere. It’s helped me trace down all sorts of inconsistencies, unexpected behavior, and hands down shady stuff… all through the iOS share sheet! From simple double checks out of safety, to hunting down a rotten CA issue this app never fails. Thank you to the dev for keeping it updated and for designing such a great tool. Wish I wrote this 4 years ago when I starting using this!

UPDATE: It’s been a few years and this app has grown to something better than I ever expected. This dev KNOWS certs. I mean, really knows. This isn’t just some easily coded generic utility tool app. You won’t find any other cert apps anywhere near as advanced as this.

Using “Google” chrome browser which sometimes a “Website” have a warning Icon on my “address” which technically says the website Protection “outdated”…This “app” on the other helps me check out (inform) what “security” issues this website having (like “dollar general” store, a website legit but their security protection is a bit outdated).

Should come with iOS

Great tool that everyone should have installed. Seriously, I don’t know why this isn’t baked into iOS. Everyone should be able to inspect certificates of the sites they visit, and this app adds the feature nicely. You don’t need to switch to the app, either. You can inspect certs of the sites you’re visiting from safari.
