dietlibc VS Tutanota makes encryption easy

The commercial success of a product totally depends on the business model you come up with, whatever be its opensource (or not) license.

Corporates have a vested interest in promoting the propaganda that only a non-xGPL opensource license can be commercialised successfully simply because they cannot freely steal the source code of a competing xGPL licensed software.

The real value of an FSF license, like the AGPL, is that it was designed to protect the copyright holders, and its users, "right to repair". And thus, it cannot be closed source by anyone (apart from the original copyright holders) once released under the said license (even if future versions are closed source, the old version under xPL remain opensource perpetually). Other open source license (that are less stringent) are prioritised to increase developer contribution. Source code under such license can be closed-source even from the original copyright holder.

But again, commercial success totally depends on the business model you come up with, irrespective of your license. The right license and the right business model will empower each other. Or cripple your business.

There are definitely some nice alternatives to glibc out there. He mentions Cosmopolitan Libc. I've used musl, uclibc, and dietlibc/libowfat in the past.

Maybe you should include the math part of a libc statically with your code. glibc is one option, or dietlibc if you want it to be as small as possible.

I agree that the implementation of printf is complex, but the interface is not. Hence calling it should not introduce bloat. Glibc adds a bunch of constructors and tables and such, whereas linking with dietlibc will probably lead to a smaller executable.

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.
