portmaster VS Tutanota makes encryption easy

There's a very good relatively new open-source GUI firewall app like this called Portmaster:

https://safing.io/

It's available for Windows and Linux

You can get your own firewall app. Portmaster by safing.io lets you open and close what ever ports you want on your windows system

amazing work OP! what's the difference between zen and portmaster? :) i would like to compare options to see which one fits my needs the best way

For Context: Technical Introduction from https://github.com/safing/portmaster#technical-introduction

Portmaster is a privacy suite for your Windows and Linux desktop.

Base Technology

- Portmaster integrates into network stack using nfqueue on Linux and a kernel driver (WFP) on Windows.

- Packets are intercepted at the raw packet level - every packet is seen and can be stopped.

- Ownership of connections is found using eBPF and `/proc` on Linux and a kernel driver and the IP Helper API (`iphlpapi.dll`) on Windows.

- Most settings can be defined per app, which can be matched in different ways.

- Support for special processes with weird or concealed paths/actors:

--- Snap, AppImage and Script support on Linux

--- Windows Store apps and svchost.exe system services support on Windows

- Everything is 100% local on your device. (except the SPN, naturally)

--- Updates are fully signed and downloaded automatically.

--- Intelligence data (block lists, geoip) is downloaded and applied automatically.

- The Portmaster Core Service runs as a system service, the UI elements (App, Notifier) run in user context.

- The main UI still uses electron as a wrapper :/ - but this will change in the future. You can also open the UI in the browser

Feature: Secure DNS

- Portmaster intercepts "astray" DNS queries and reroutes them to itself for seamless integration.

- DNS queries are resolved by the default or configured DoT/DoH resolvers.

- Full support for split horizon and horizon validation to defend against rebinding attacks.

Feature: Privacy Filter

- Define allowed network scopes: Localhost, LAN, Internet, P2P, Inbound.

- Easy rules based on Internet entities: Domain, IP, Country and more.

- Filter Lists block common malware, ad, tracker domains etc.

Feature: Network History ($)

- Record connections and their details in a local database and search all of it later

- Auto-delete old history or delete on demand

Feature: Bandwidth Visibility ($)

- Monitor bandwidth usage per connection and app

Feature: SPN - Safing Privacy Network ($)

- A Privacy Network aimed at use cases "between" VPN and Tor.

- Uses onion encryption over multiple hops just like Tor.

- Routes are chosen to cover most distance within the network to increase privacy.

- Exits are chosen near the destination server. This automatically geo-unblocks in many cases.

- Exclude apps and domains/entities from using SPN.

- Change routing algorithm and focus per app.

- Nodes are hosted by Safing (company behind Portmaster) and the community.

- Speeds are pretty decent (>100MBit/s).

Portmaster itself is open source (https://github.com/safing/portmaster)

Then install https://safing.io/ (Portmaster); it's free.

Hi HN, we are the developers from Tuta (formerly Tutanota), the German end-to-end encrypted email provider, and we recently released the world's first post-quantum encryption for email.

We have included a full technical write-up of the cryptography involved in these changes and we have released it for open public review.

This document specifies TutaCrypt, a protocol designed for hybrid email encryption in Tuta Mail. The protocol combines a classical Elliptic-Curve-Diffie-Hellman key exchange with a post-quantum KEM. The goal is to replace the usage of RSA in Tuta Mail.

In the remainder of this document we describe some preliminaries such as the cryptographic primitives used. We define the core algorithms of the protocol and describe the flow of messages between the communicating parties. Finally, we discuss the security properties and some limitations of the protocol in its current form.

We are eager for your constructive feedback. All cryptography related source code is available for review and experimenting here: https://github.com/tutao/tutanota/blob/master/src/api/worker...

If you have any questions or comments related to post-quantum cryptography please let us know in the comments!

Tutanota - Free secure email account service provider with built-in end-to-end encryption, no ads, no tracking. Free 1GB storage. Which is also partially open source, so you can self-host.

You are probably using a window manager and Electron is not able to detect the secret service backend you have installed. We recently switched to Electron’s built in api for storing credentials, which is the reason for this issue. https://github.com/tutao/tutanota/issues/6265

Tuta Mail (version 3.119.3): Encrypted email & calendar service - easy to use, secure by design.

A look at tuta.com and tutanota.com demonstrates that Tuta is using an Amazon Start of Authority (SOA) DNS record and 4 corresponding Amazon Name Server (NS) DNS records.

rich coming from tuta who still lack a onion based login. this ticket from 2018 was locked as off-topic. https://github.com/tutao/tutanota/issues/528

as lenin said, the best way to control the opposition is to lead it. for me, unless the company has been raided by the government they simply cannot be trusted.

apple proudly advertises privacy billboards while sharing everything they are asked under shadow laws. absolute hypocrisy and double standards. but then they wouldnt be where they are without government money and favours.

Have a non business paid account. Can you change your current tutanota.com email to the tuta.com email?

I have an at tutanota.com account. All of a sudden, this evening, it disconnected and I haven't been able to re-access my account. It actually seems like the whole platform is down, but maybe that's just the context from my devices.

I have a fairly recent free account that I believe was on the domain tutanota.com which I can no longer log into.
