Yes, today in France, the price of houses is relatively high in the countryside and difficult to access for a modest family. I bought this house with my wife thirty years ago for a very low price but with a lot of work to do. It took me 20 years to finish everything with little means… it was not always easy, but I would never have returned to the city for anything in the world.. I hope my English is not too bad…

I really like the concept of “twt”. It’s the perfect blend of txt and twtxt. An abbreviated form. Even though it’s the name given to posts, I personally find it very nice.
#twtxt

Nice photo. The fire looks like magic.

I don’t think so, at least the tests I did passed. If you’re pretty sure it’s a bug, please create an issue in the repository with the specific case and I’ll investigate it.
There are 2 buttons to make replicas, one makes a replica in the thread where the twt is located (this is the one that should be used the most, as it serves a thread), the other creates a replica to a specific twt.
I’ll let you know a bit about the status: I’m just now implementing the thread screen. There you can be sure where you are. It’s a bit confusing right now, sorry. I think the client is still in alpha. When I’ve finished what I’m doing, and the direct message system, I’ll freeze development and focus on creating more tests, looking for bugs and making small visual adjustments.

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

I’m happy to note that tomorrow is already Friday. However, looking back on the week, I can’t think of anything terribly useful I’ve accomplished. Hard to distinguish it from a plain zero. Again. Hmm. Anyway, looking forward to the weekend.

@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?

The Americans are spreading links to sites with European alternatives for popular services, yet here I am, scheduling appointments with the construction workers over WhatsApp.

@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.

I always wanted to go and live in the country side, it seems I can’t manage to for financial reasons

@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

@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”.

@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 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?

Ashram - Lucky’s Song (My Dog)
https://youtu.be/oJ37mmym_LA

hello @c8e00 ! All the best to you too, despite a very disrupted world… I live in France, lost in the countryside.

@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)?

@andros@twtxt.andros.dev I have really tried to get behind it. For an implementation for my TwtxtReader (PHP) I simply lack the knowledge of the standard-openssl parameters.
All my solution approaches require “nonce” or “initialization vector” on one or the other side. In addition, the “magic numbers” (“Salted__”) were not consistent in my tests.

@prologic@twtxt.net I wish getting a static IP and a (more) stable internet connection wasn’t so hard over here. Then I could do proper self-hosting as well. But as it stands, I need some rented VPS.

I could go ahead and just use the VPS for the IP, i.e. forward all traffic through Wireguard to a box here at home. Big downside is that the network connection would be even slower than it already is and my ISP breaks down all the time for a few minutes … it’s just bad overall and much easier/better to rent a VPS. 🫤
