It has recently come to our attention that there are sites that publish "unofficial TWRP" images. These are versions of TWRP that are being distributed out of our authority based on forks and internal unpublished sources from people not associated with our site. Unfortunately we don't have a lot of time to police these sites and images. Some are forks of our project that are not forwarding back patches to our gerrit site, or they just cherry-pick open commits and release them before the patchsets can be vetted and merged to the baseline. Some sites just scrape images from our download sites and post them as their own.
We try to pride ourselves on the security and established chain of repudiation by using GPG signatures and publishing SHA2 hashes to show the images haven't been modified from the original build on our jenkins server. Our jenkins build logs are able to be seen by anyone wanting to verify how their image was built. Our sites are using Let's Encrypt for end-to-end TLS encryption. We are not serving any pages or images outside of this TLS end-to-end encryption.
We are receiving much community support but unfortunately the aforementioned unofficial versions of TWRP can never meet any type of veracity from TeamWin. Please consider your security before installing any unofficial TWRP to your device.
