Chromium Ozone/Wayland: the last mile stretch
Lets start with some context, the project consists of implementing, shipping and maintaining native Wayland support in the Chromium project. Our team at Igalia has been leading the effort since it was first merged upstream back in 2016. For more historical context, there are a few blog posts and this amazing talk, by my colleagues Antonio Gomes and Max Ihlenfeldt, presented at last year’s Web Engines Hackfest. Especially due to the Lacros pr … ⌘ Read more

@eapl_en@eapl.me Your notes are amazing! I’m going to save them for when I do my implementation. Great job!

@aelaraji@aelaraji.com Works 👌

@prologic@twtxt.net Those aren’t actually serving anything public-facing. I’ve thought about it, but for now I’m sticking with VPSs, partly because I don’t relish the risk of weeks of downtime if something goes wrong while I’m travelling.

Okay, I won’t park there.

1972 UNIX V2 “beta” resurrected from old tapes
There’s a number of backups of old DECtapes from Dennis Ritchie, which he gave to Warren Toomey in 1997. The tapes were eventually uploaded, and through analysis performed by Yufeng Gao, a lot of additional details, code, and software were recovered from them. A few days ago, Gao came back with the results from their analys of two more tapes, and on it, they found something quite special. Getting this recovered version to run was a bit of a … ⌘ Read more

@bender@twtxt.net Hmmm, does that mean it’s not that popular in the US? 🤔

I hope not, @bender@twtxt.net! I haven’t checked, but I’d reckon it to be at most a single digit MiB number. How wrong am I?

@nff@www.noizhardware.com Nice! Yeah, it’s all about having fun. :-) The simplicity got me hooked. Happy hacking!

@off_grid_living@twtxt.net No right click thing, but in the terminal:

convert -strip -quality 70 -resize 300x original.jpg resized.jpg

“original.jpg” being the filename of the input file and “resized.jpg” the filename of the output. You can play around with the width, “300x” means 300 pixels wide and the height is determined automatically to still remain in the same ratio. The quality is how much to compress it. The closer to 0 the value gets, the worse the result, but also smaller in file size. More towards 100 and the quality improves together with a larger file size.

You have to install the package “imagemagick” for this to work, I believe.

@off_grid_living@twtxt.net Oh, I’m ready for my retirement, too. :-D Still have some decades to go, unfortunately.

@off_grid_living@twtxt.net You could try starting it in the terminal in order to spot errors. Just open the GNOME Terminal or something like that and then type in “kolourpaint” and hit Enter.

@eapl.me@eapl.me Nope, I switched to the openssl library in PHP. But our rubberducking 🦆 seems to be working. Your find https://crypto.stackexchange.com/a/79855 for the IV generation may be the breakthrough …

@bender@twtxt.net Lol! :-D

here is my progress so far: https://github.com/eapl-gemugami/twtxt-direct-message-php
The encryption part seems to work, if I decrypt it the message with OpenSSL.
I think it can help you for some key parts not well explained in OpenSSL documentation.

@andros@twtxt.andros.dev reading your spec I wrote a few notes here: https://github.com/eapl-gemugami/twtxt-direct-message-php/blob/main/direct_message_spec.md

@arne@uplegger.eu I haven’t check your repo yet, although you are using sodium, right?

@arne@uplegger.eu Here are the results of the german jury:

😭

@eapl.me@eapl.me Here is what I’ve got so far: https://github.com/upputter/testing-twtxt-dm

There is a “00_well_known_message.enc” file, which I have the encryption paremters for (https://github.com/upputter/testing-twtxt-dm/blob/9fdf3be6aa8fe810a4cb275375dbb3d4a2a958ee/wellknown_test.php#L28).

According to my finding, I assume, that the saltsize in openssl is “8” and the PBKDF2 algo is “sha256”.

Those are some impressive wigs: https://imgur.com/gallery/life-imitates-video-game-5KlJBhj I wonder how it feels to wear such a thing for a day – especially in summer. 😅🥵

@andros@twtxt.andros.dev Could you share (perhaps in the extension document) the private key for alice?

I want to compare that I can read the encrypted message both from OpenSSL CLI and from the PHP OpenSSL library, following the spec.

trying to implement it quickly, I get the same questions than you

# https://www.php.net/manual/en/function.openssl-pbkdf2.php
    $password = $sharedKey;
    $salt = openssl_random_pseudo_bytes(16);  # What's the salt length ?
    $keyLength = 20;  # What's the key length here ?
    $iterations = 100000;
    $generatedKey = openssl_pbkdf2($password, $salt, $keyLength, $iterations, 'sha256');
    echo bin2hex($generatedKey)."\n";
    echo base64_encode($generatedKey)."\n";

    $iv = openssl_random_pseudo_bytes(16); // AES-256-CBC requires 16-byte IV
    $cipherText = openssl_encrypt($message, 'aes-256-cbc', $generatedKey, OPENSSL_RAW_DATA, $iv);
    return base64_encode($iv . $cipherText);

I haven’t taken a look into that extension, although I think you could use the OpenSSL library: https://www.php.net/manual/en/function.openssl-encrypt.php

@arne@uplegger.eu With the OpenSSL option -p one can get an output of salt, key and iv. My stupid PHP-code can get everything right from the encrypted data (from OpenSSL) - except the iv! Damn “evpKDF” 😔

@prologic@twtxt.net I’ve been there yesterday w/o success.

@arne@uplegger.eu I think you want to use the sodium_crypto functions/modules for PHP 🤔🤔

@arne@uplegger.eu Hi! I love that you’re implementing it! Maybe, when we’re both done, we could test the clients by communicating both.
I don’t think I’m going to be able to help you much, my knowledge of OpenSSL and PHP is not as high as I’d like it to be.
Maybe the OpenSSL version uses SHA-1 by default in PHP. Or that the IV is derived together with the key (not generated separately). But I’m not able to answer your questions, sorry.
I’m invoking the commands directly, without any libraries in between. Maybe that would help you?

Had some fun with my old Mandelbrot renderer: https://movq.de/v/83110057f5/

@arne@uplegger.eu Well, just for my understanding. The command:
echo "Lorem ipsum" | openssl enc -aes-256-cbc -pbkdf2 -iter 100000 -out message.enc -pass file:shared_key.bin
will take the input string from echo to openssl. It then will

1. use the content of shared_key.bin as password
   
2. use PBKDF2 with an iteration of 100000 to generate a encryption key from the given password (shared_key.bin)
   
3. use the PBKDF2 generated key for an aes-256-cbc encryption
   

The final result is encrypted data with the prepended salt (which was generated by runtime), e.g.: Salted__q�;��-�T���"h%��5�� ....

With a dummy script I now can generate a valide shared key within PHP ‘openssl_pkey_derive()’ - identical to OpenSSL.
I also can en-/decrypt salted data within my script, but not with OpenSSL. There are several parameters of PBKDF2 unknown to me.

Question:

1. Is the salt, used by aes-256-cbc and PBKDF2 the same, prepended in the encrypted data?
   
2. Witch algorithm/cipher is used within PBKDF2: sha1, sha256, …?
   
3. What is the desired key length of PBKDF2 (https://www.php.net/manual/en/function.openssl-pbkdf2.php)?
