Experimental fork of F-Droid to use TLS ECH with Cloudflare as the default host
About this app
This is a demo fork of F-Droid to serve as an example app built on the development fork of Conscrypt which supports TLS Encrypted ClientHello (ECH). ECH is the next version of the TLS protocol that encrypts internet traffic and puts the "S" in HTTPS. It makes it possible to encrypt all of the metadata that is possible to encrypt in the TLS negogiation. It is a test case for interoperability between various implementations, platforms, and networks. The Encrypted ClientHello (ECH) mechanism (IETF draft spec) is a way to plug a few privacy-holes that remain in the Transport Layer Security (TLS) protocol that's used as the security layer for the web. OpenSSL is a widely used library that provides an implementation of the TLS protocol. The DEfO project is developing an implementation of ECH for OpenSSL, and various clients and servers that use OpenSSL as a demonstration and for interoperability testing.
This uses the mirror of f-droid.org that is on Cloudflare with ECH enabled: https://cloudflare.f-droid.org
DEfO was initially funded by the Open Technology Fund, and subsequently by the National Democratic Initiative. Tolerant Networks Ltd. and people from the Guardian Project are doing the work in DEfO.

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)
Enable "Allow from this source" for your browser or file manager
Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be ie.defo.ech_apps is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 0.2 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall DEfO ECH Apps first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of DEfO ECH Apps, and a listing is removed when the evidence for it stops holding up.

The signing certificate fingerprint for this release is on record, so a build that does not match it did not come from this publisher.

A listing is only as good as its corrections. If a source is broken, a signature looks wrong, or this app should not be here, tell the moderation team.
