Editor's Overview

Keyoxide is a security application developed by Berker Sen, packaged as a single Android APK of version 2.4 weighing in at 35.51 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 35.51 MB, so it installs quickly even on modest connections.
This build is signed by "Berker Sen" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

A modern, secure and privacy-friendly platform to establish your decentralized online identity

Keyoxide allows you to prove “ownership” of accounts on websites, domain names, IM, etc., regardless of your username.

That last part is important: you could, for example, be ‘alice’ on Lobste.rs, but ‘@alice24’ on Twitter.
And if your website is ‘thatcoder.tld’, how are people supposed to know that all that online property is yours?

Of course, one could opt for full anonymity! In which case, keep these properties as separated as possible.
But if you’d like these properties to be linked and, by doing so, establish an online identity, you’ll need a clever solution.

Enter Keyoxide.

When you visit someone’s Keyoxide profile and see a green tick next to an account on some website,
it was proven beyond doubt that the same person who set up this profile also holds that account.

Frequently Asked Questions

Is Keyoxide free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does Keyoxide require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Keyoxide safe to install?
We link to the exact APK published by Berker Sen. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update Keyoxide?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
