Encrypted peer-to-peer IM for data security. Own data, own privacy. (Rust+Flutter)

Do you have watched "Black Mirror" The first episode of the second season? The story of the “rebirth” to accompany the lover based on the text, photos, videos and other information posted on the Internet.

So is this "data" accessible to everyone or some companies?

What we want to do is protect this data and privacy. you can see details what we are doing.

ESSE (Encrypted Symmetrical Session Engine) An open source encrypted peer-to-peer system for own data security, and allow data to be sent securely from one terminal to another without going through third-party services. Also provides data visualization and interactive entry. With a friendly interface for users, it transforms abstract data concepts into software that everyone can actually experience.

Slogan: My place, my rules.

ESSE, positioned as an engine. The engine is coded in Rust language based on TDN framework, and the cross-platform user interface is built using Flutter.

Install

🚀 Use pre-compiled executable

Download

🚲 Compile from source

1. Pre-installed

• Rustup install
• Rust (Lastest Stable version)
• Flutter (Lastest Stable channel)

2. Compile Rust code to dynamic link library (FFI)

2.1. Auto-compile script

It is recommended to use rust.sh to auto-compile the Rust code

2.2. Manually compile

Linux / MacOS / Windows

• cargo build --release

Linux

• cp target/release/libesse.a core/linux/share/libesse.a

MacOS

• cp target/release/libesse.a core/macos/share/libesse.a

Windows

• cp target/release/esse.dll core/windows/share/esse.dll
• cp target/release/esse.dll.lib core/windows/share/esse.dll.lib

Android

1. Add your android device target

• rustup target add aarch64-linux-android
• rustup target add armv7-linux-androideabi
• rustup target add x86_64-linux-android

2. Configure your NDK

3. Build the jniLibs

• cargo build --release --target=aarch64-linux-android
• cp target/aarch64-linux-android/release/libesse.so core/android/src/main/jniLibs/arm64-v8a/

iOS

1. Install lipo
2. cargo lipo --release
3. cp target/universal/release/libesse.a core/ios/share/libesse.a

3. Run flutter to build binary

• Run flutter run or flutter run --release in terminal, or
• for Android, run flutter build apk, or
• for Linux, run flutter build linux, or
• for MacOS, run flutter build macos, or
• for Windows, run flutter build windows

esse's Issues

[Feature] encrypted local SQLite database.

What ?

Encrypted local SQLite database.

Why ?

Encrypted everywhere.

How ?

• use sqlcipher to handle SQLite. use rusqlite and features bundled-sqlcipher-vendored-openssl. (better for cross-compile)
• update tdn_storage API. use open(path: PathBuf, password: &str)
• update ESSE
  • account.db: use device's local secret (every device drive it randomly when first launch) to encrypt/decrypt.
  • account's database: use user encrypt key (which is encrypted by user's PIN and secret) to encrypt/decrypt.

Next version 0.6

What is the plan of 0.6 ? (Breaking changes)

List

• Data structure defined Data-Protocol.
• Local encrypted database.
• Refactor distributed synchronization between devices.
• Optional cloud-based data centre.
• DAO and organization application (Maybe in 0.7)

Making installer, and publish to app store.

For safer and more convenient

Android

Now that is apk, can install, but we need to upload to Play Store

IOS

First, I need to register an IOS developer account. And then upload to App Store.

macOS

Also need account, and upload to App Store.
Need test on M1 device (arm64)

Windows

Make Windows installer. Try msix

Linux

Upload to snap

error: $./rust.sh in zsh

$ ./rust.sh linux          
./rust.sh: 2: Syntax error: "(" unexpected

Fix

Add default sh #!/bin/bash to rust.sh

#!/bin/bash
#### Default Current Machine
function current() {
    cargo build --release

    ## check now os.
}
...

[Feature] add ETH wallet to ESSE.

Support ETH and ERC20.

.

Add NFT as account avatar.

I think NFT can be as avatar.

When import an account with secp256k1, it will have ETH address. So we can use a NFT that belongs to this address as avatar.

I have a problem with the installation

[Feature] group chat avatar use members.

Avatar limit is 4, like 2x2 grid.

Problem with understanding logic.

Can you explain why the Rust is in the same file as Flutter? I am trying to understand all the logic to be able to install this locally. I have problems running the application in XCode. I only get splash screen for a few seconds and kick me out.

[Doing] use "PeerID" replace "ESSE ID & PeerID".

Now, if you search a friend, you need to know ESSE ID and PeerID.
How about only use PeerID ?

Advantages

1. Easy to understand
2. User info is smaller
3. Easy to handle network connect/disconnect

Disadvantages

1. Can't at same time online multiple accounts. (one account is one PeerID)
2. Login before network start
3. Logout will make network stop
4. Change account, restart network
5. Difficult to identify whether connecting to cloud service

Step

1. chamomile support stop network, restart network, and TDN also add
2. Refactor account system

How

use new ID (string)

pub fn id(peer: &tdn_types::primitive::PeerId) -> String {
    bs32::encode(&peer.0)
}
