From the project README

An excerpt from the repository, fetched Nov 13, 2026.

Read the project’s introduction

End-To-End End-To-End is a crypto library to encrypt, decrypt, digital sign, and verify signed messages (implementing OpenPGP and OTR). This is the source code for the End-To-End library. It's built upon a newly developed, JavaScript-based crypto library. End-To-End implements the OpenPGP standard, IETF RFC 4880, enabling key generation, encryption, decryption, digital signature, and signature verification. We're releasing this library to enable community review. For more background, please see our blog post. Documentation for the project is stored in our Wiki. If you're planning to contribute to the project, check out our Contributor guide. A few projects have been built on top of this library, to list a few: E2EMail - A Gmail client that exchanges OpenPGP mail. Freedom JS - A framework for building peer-to-peer (P2P) web apps. uProxy - A browser extension that lets users share their internet connection. Google End-to-End Extension - Google End-to-End Chrome Extension (not ready for general use). Yahoo End-to-End Extension - A fork of Google's End-to-End for Yahoo mail.

Google End-to-End: Any update?

It's been a year since Google posted this update[1] on their end-to-end project and a month since the last commit.[2] Yahoo announced a forked end-to-end extension in March[3] and while commits have been more frequent[4], they haven't released either. Does anyone have any update on these?

Seems to still be receiving commits as of a few days ago > https://github.com/google/end-to-end I was waiting on smartcard support in that project myself

There is a Chrome extension that does something like that: https://github.com/google/end-to-end Obligatory warning: it's in an alpha state according to the readme, so you shouldn't use it yet for real.

See https://github.com/google/end-to-end/wiki/Key-Distribution. In short, we don't invest much into WoT.

For better or worse, "End-To-End" is the specific Google Chrome extension being discussed in the article: https://github.com/google/end-to-end/ Proper capitalization would help; Google choosing a less overloaded name in the first place would have helped more.

I'm an developer on E2E team as well and can confirm that there's no 'hardening' going on. E2E is, to the best of our knowledge and we have expressed what that exactly means in our threat model: https://github.com/google/end-to-end/wiki/Threat-model. E2E is under Google VRP (https://www.google.ch/about/appsecurity/reward-program/), so if you're aware of any vulnerabilities, let us know. E2E extension is not production ready, but I myself am using the compiled version as it is, in my biased opinion, the most secure of existing PGP-in-the-browser extensions.

One of the developers here: Yes, the Keyring reimplementation is in progress and ends very soon. After the redesign, applications built on top of E2E library will be able to use different sources of both public and private keys (so it's easy to do integrations with GnuPG, hardware keys HKP, or e.g. Facebook). The API will be similar to what's in https://github.com/google/end-to-end/wiki/Keyring.

In How to support PGP encryption in Gmail

viraptor·Aug 26, 2015

FAQ is a bit confusing. They say there's only one keyring, but at https://github.com/google/end-to-end/wiki/Keyring they admit it was not a great idea and that they're splitting the responsibilities. Based on the last planned implementation (External Key Manager (GnuPG bridge, other hardware, network oracle etc..)), I hope it will "just work" with hardware keys.

Yahoo and Google are both working on end-to-end e-mail options. https://github.com/google/end-to-end https://github.com/yahoo/end-to-end An even harder problem, maybe: how could we make it so communications intermediaries don't know your social graph? The most exciting idea in this direction I know of is AGL's Pond: https://pond.imperialviolet.org/ But it comes with some more severe tradeoffs than just end-to-end encrypting your e-mail, like deliberately introducing delays in sending and receiving messages in order to create ambiguity about when communication took place.

Has anyone checked https://github.com/google/end-to-end ? I want to believe google did their due diligence.

In Cryptographic Right Answers

chrisper·May 10, 2015

Yes. Why not? You just have to encrypt the message before sending it and decrypt it after you received it. https://github.com/google/end-to-end I think the actual challenge is to do it with senders/receivers you do not know. I do not have enough secuirty experience to be able to answer how you can encrypt something on one end but decrypt it on the other hand without knowing the key? I guess something like HTTPS would work.

They have a Wiki that has build/install instructions: https://github.com/google/end-to-end/wiki/Build-instructions. Basically, clone the Git repo then do: ./do.sh install_deps ./do.sh build_extension This results in an extension folder that can be installed via Chrome's developer mode.
