Android Email PGP

Summary
This Xposed module aims at adding PGP support to the native android email client.

Introduction
I started creating this module because I started using PGP in my daily mail exchange with some friends and colleagues, but I was unsatisfied with the support of PGP in Android. There is K9-Mail and an addon, but I really like the native Android email app more, so I started working on this.
I tested this app on CM11 (Android 4.4.4) and the native installed email application. Samsung/HTC email clients won't work.

Download
Download it straight from Xposed Repository

Source

Features

Import your keys (private & public) into the app
Decrypt encrypted messages
English and German translation

Current limitations

You may only import keys by opening an *.asc file from anywhere on the device (Dropbox etc. work as well) by choosing to open the file with my app

Bugs

Headerviews in the emails get added multiple times sometimes

This is a marvelous module. I am using AguaMail, would be nice if you can perhaps extend it for third email apps in the future.

Great Idea!

This is a great idea, and a good way to implement it. Thanks for thinking of it. I look forward to using this..

Sadly I don't see a lot of activity here although the idea has a lot of merit in this day and age.

I suspect that a lot if heavy mail users are using POP3 or I'LL clients, such as K-9, Kaiten and a few others. Some already have the ability to work with APG which has been around for a while but not much us happening with it.

A true, well working PGP client would be nice to see.

Thank you, I think the limited feature set is the problem here - I am working on implementing open keychain for faster development progress as I do not need to handle all the PGP related stuff myself..

more encryption by everyone is more better

Was this in part inspired by webPG.org ?
(not those nefarious rascals acting as keymaster and gatekeeper)

IMAP is my druthers (when both server side searching and filtering is available). Let POP die.

No not really, it is more inspired by my personal need. I am using PGP in thunderbird as my mailclient on my desktop with some friends and I was annoyed that I can not access emails when I am on the go.

Unfortunately no futher progress until now..

I'm looking forward to this. I much prefer the gmail app over k9!

Definitely, but work is stopped for now, I am waiting at least for the new gmail 5.0 apk to be finally released

Any news? I'm keeping my fingers crossed for a gmail update.

No news for now, at least nothing interesting. I decompiled the gmail 5 apk, but it is obviously obfuscated.. That means all the classes are only named a.java, b.java,...
That makes it extremely hard to understand the logic of the app and it's source and to find the interesting points to add method hooks. I need much more time to look into this and to understand it..

But like you I really want to have it working in the current gmail apk..

Keep us posted.

I cant open settings in the PGP app..

BySteven · Jan 5, 2016

Doesn't work (CM11, Android 4.4.4)

Hi,

I really would like it to work, but it doesn't:
- cannot open settings
- can only import public keys, secret keys will not be displayed in the list altgough they should work (single key as asc)

schwarzlowe · Aug 18, 2016

Any update on this?

mfunction · Dec 10, 2016

Is this officially dead? I use K-9 but an alt is welcome.
