Ideas for Hexlish improvement

In my initial off-the cuff idea the 'spacing characters that don't belong' can just be filtered out or parser-inserted where spaces are found in the text just prior to encoding.

Use the space character as a stream shift register or top-bit range toggle in the encoding logic. Then any punctuation character can be placed after the space. The parser will pick up the characters, re-encode them, and toggle back at the next space. A checker would need to look for double toggle characters in sequence.

This would necessitate swapping out one alphabet character and it would require slightly more complex logic for simple ciphers to use. But it goes in a doable direction.

Abbey Schnabel suggested using the dot (.) as a character and marker and rendering Hexlish as all lower-case. These are sound improvements to legibility.

At first glance, I can't help but think spaces would be better. As for rendering it all lower-case, it could actually be case insensitive, and every letter could be treated as lowercase or uppercase regardless, using a shift or toggle nybble in the encoding stream.

It is too complex for me to wrap my brain around all the potential quirks right now, so maybe the first week of next month I'll sit down and really brainstorm it on paper.

Hexlish Alphabet for English, Constructed Languages and Cryptography: Automatic, Structural Compression with a Phonetic Hexadecimal Alphabet

DOI : https://doi.org/10.5281/zenodo.13139469

Hexlish is a legible, sixteen-letter alphabet for writing the English language and for encoding text as legible base 16 or compressed binary. Texts composed using the alphabet are automatically compressed by exactly fifty percent when converted from Hexlish characters into binary characters. Although technically lossy, this syntactic compression enables recovery of the correct English letters via syntactic reconstruction. The implementer can predict the size of the compressed binary file and the size of the text that will result from decompression. Generally it is intuitive to recognize English alphabet analogues to Hexlish words. This makes Hexlish a legible alternative to the standard hexadecimal alphabet.

The Signal Protocol in Rust

TL;DR: I have open-sourced a #Rust implementation of the #SignalProtocol that compiles to #WASM for #Browser-based #P2P messaging, overcoming the #Nodejs limitations of the official library.

I am sharing my implementation of the Signal Protocol designed specifically for the #Frontend. While the official libsignal is the gold standard, its #JavaScript targets are often optimized for Node.js, which creates integration challenges for client-side web applications.

My version is built in #RustLang and compiles to #WebAssembly, utilizing #ModuleFederation to provide robust #Encryption for decentralized environments. It currently powers the end-to-end security for my series of #P2P messaging projects.

Protocol Demo:
https://signal.positive-intentions.com/

P2P Messaging roadmap:
https://glitr.io/docs/technical/roadmap

I am looking for feedback from the #Dev and #Infosec community. If you have experience with #Cryptography audits or formal-proof verification, I would appreciate your eyes on the codebase as I work toward a more finished state.

"Security personnel around the world are on high alert Tuesday following the discovery of eight TLS certificates with private keys so weak they could allow anyone to mint trusted browser and app credentials for any site on the Internet.

As of late morning Tuesday, browser makers and some major apps and programming languages had blocked all eight of the intermediate certificates. There are no reports of certificate transparency logs, which track the issuance of all browser-trusted certificates, showing the compromised keys being used maliciously. The threat remains far from over, however, because it will be hard and time-consuming to update other key parts of the Internet, such as Linux distributions and embedded and Internet of Things devices.

The eight intermediate certificates belong to India-based certificate authority eMudhra Limited. An informal advisory published to emudhra.we-have-a-problem.com over on Tuesday posted the message “We have a problem here – Wayne.” The words were digitally signed using the private key of one of the eMudhra certificates. With proof that the reporting party had control of the key, defenders scrambled because the same key could be used to sign unauthorized certificates that would be trusted by millions of servers worldwide."

WhatsApp keeps doing it: every a couple of months you wake up and suddenly you can't access your chats anymore, not possible to read important saved notes, etc. you are welcomed with this screen that forces you to update the app, you might be in vacations with expensive roaming data or very bad connectivity or if you are unlucky enough you might be in a country where the app store is not accessible, your data is not YOUR data in WhatsApp, and the reality is: you can lose it at any time they want to take it away from you

On the other side, ArcaneChat users can sleep without worries at night knowing that when they wake up they can keep accessing all their chats, messages and being able to search and use mini-apps, even while offline

[demo] https://files.octade.net/

I drafted a prototype for a PHP server application that automatically hashes and signs files and presents visitors with verification archives containing digital signatures for offline verification. The site allows readers to view, download, hash, and verify signatures of files. Since I occasionally like to publish puzzles and bits of cryptology, I just had to make this to scratch the old itch.

The neat thing about this design is that the current version has zero JavaScript. It uses CSS3 hacks with anchors and URL probing to emulate JavaScript and AJAX functionalities for modal dialogs to present server-side JSON data as HTML text.

When I upload files or documents to the server, the interface automatically presents them to the user in a grid. So now all I have to do is upload files and documents and the server generates the site.

The reader can then click buttons to hash, sign, view, verify, and download files.

GnuPG and OpenSSL Signatures are generated automatically on user demand. The site visitors can download these signatures and the public keys to verify files.

What should I add / change in the application and its interface?

What accessibility components might be warranted?

Should the application parse and present EXIF data, or is that too much?

Al Gore Invented the Internet.
Joe Biden invented PGP encryption.
Cypherpunks write code.

Joe Biden gifted humanity with PGP encryption (in a roundabout way). Phil Zimmermann created PGP in response to a anti-privacy bill clause proposed by Senator Joe Biden.

https://www.americanscientist.org/article/cypherpunks-write-code

"In 1990, the FBI launched an over-the-top crackdown on computer hackers, known as Operation Sundevil. This was swiftly followed, in early 1991, by a proposed piece of U.S. Senate legislation that would force electronic communications service providers to hand over people’s personal data. (The key clause, S.266, was pushed by the then chairman of the U.S. Senate Judiciary Committee, Senator Joe Biden.)"

"On learning of Biden’s S.266 clause, Zimmermann feverishly set out to complete the project, almost losing his house in the process. When he finished his software in 1991, he published it all online, free for anyone who wanted to use it. He called it “Pretty Good Privacy,” or PGP for short, and within weeks it had been downloaded and shared by thousands of people around the world. “Before PGP, there was no way for two ordinary people to communicate over long distances without the risk of interception,” said Zimmermann in a later interview. “Not by phone, not by FedEx, not by fax.” It remains the most widely used form of email encryption to this day."

https://www.congress.gov/bill/102nd-congress/senate-bill/266

"SEC. 2201. COOPERATION OF TELECOMMUNICATIONS PROVIDERS WITH LAW ENFORCEMENT. It is the sense of Congress that providers of electronic communications services and manufacturers of electronic communications service equipment shall ensure that communications systems permit the government to obtain the plain text contents of voice, data, and other communications when appropriately authorized by law."

"New research shows that behaviors that occur at the very lowest levels of the network stack make encryption—in any form, not just those that have been broken in the past—incapable of providing client isolation, an encryption-enabled protection promised by all router makers, that is intended to block direct communication between two or more connected clients.

The isolation can effectively be nullified through AirSnitch, the name the researchers gave to a series of attacks that capitalize on the newly discovered weaknesses. Various forms of AirSnitch work across a broad range of routers, including those from Netgear, D-Link, Ubiquiti, Cisco, and those running DD-WRT and OpenWrt.

AirSnitch “breaks worldwide Wi-Fi encryption, and it might have the potential to enable advanced cyberattacks,” Xin’an Zhou, the lead author of the research paper, said in an interview. “Advanced attacks can build on our primitives to [perform] cookie stealing, DNS and cache poisoning. Our research physically wiretaps the wire altogether so these sophisticated attacks will work. It’s really a threat to worldwide network security.” Zhou presented his research on Wednesday at the 2026 Network and Distributed System Security Symposium.

Paper co-author Mathy Vanhoef, said a few hours after this post went live that the attack may be better described as a Wi-Fi encryption “bypass,” “in the sense that we can bypass client isolation. We don’t break Wi-Fi authentication or encryption. Crypto is often bypassed instead of broken. And we bypass it ;)” People who don’t rely on client or network isolation, he added, are safe."

Seven people are put on trial in #France for:
- using encrypted apps like Signal
- participating in digital security training

“8 December” case: why is encryption on trial?
"On 3 October, the trial of the so-called “8 December” case began. Seven people are prosecuted for being a “terrorist group”.

The intelligence services in charge of the judicial investigation (Direction générale de la Sécurité intérieure, DGSI), the National Antiterrorist Prosecution Office (Parquet National Antiterroriste, PNAT), and the investigating judge based their case on the fact that the defendants were using different tools to protect their privacy and encrypt their communications on a daily basis.

This trial is part of an increased political push by states and law enforcement for surveillance measures and the criminalisation of encryption. That is why the trial is crucial in the battle against the state’s ongoing attempts to criminalise commonplace, secure and healthy digital practices.

EDRi member in France La Quadrature du Net has continuously defended people’s right to privacy and fought for strong protections of everyone’s digital security. Now, once again, they stand up for the last pillar of our digital #security – #encryption."

Hexlish Alphabet for English, Constructed Languages and Cryptography: Automatic, Structural Compression with a Phonetic Hexadecimal Alphabet

DOI : https://doi.org/10.5281/zenodo.13139469

Hexlish is a legible, sixteen-letter alphabet for writing the English language and for encoding text as legible base 16 or compressed binary. Texts composed using the alphabet are automatically compressed by exactly fifty percent when converted from Hexlish characters into binary characters. Although technically lossy, this syntactic compression enables recovery of the correct English letters via syntactic reconstruction. The implementer can predict the size of the compressed binary file and the size of the text that will result from decompression. Generally it is intuitive to recognize English alphabet analogues to Hexlish words. This makes Hexlish a legible alternative to the standard hexadecimal alphabet.

Newscard creates a decentralized, encrypted, named record paste bin.

[git repo] https://codeberg.org/OCTADE/newscard (use most recent version only)

With a single command, name the card, snarf the file and encrypt it.

With another command, push the encrypted file to the public network.

With another short command, snarf a file from the network.

Only users knowing the name [key] of the record will be able to decrypt it.

If a strong passphrase is used to name the file, it will be very secure.

This is useful for quickly snarfing, encrypting, and publishing a text file:

$~: card enc [passphrase] [file]
$~: card put [passphrase]

It is useful for retrieving a text file with just a key:

$~: card get [passphrase]
$~: card show [passphrase]

If and when you want the general public to access the record just share the keyword.

Newscard uses nine (9) (NINE) layers of encryption with OpenSSL chacha20 cipher.

Newscard generates 9 each of: cipher keys, salts, key iteration parameters.

It would be nice if something like this were added to the ActivityPub protocol, such that keyword[@]host.url would do the same thing. Then secret text records could be stored securely for later retrieval or revelation.

Playing card of the Jack of Clubs. The Jack is a moustached man in a black top hat and suit in a oval center cameo. The colors are inverted so that everything on the face is black except the lines which are white, like a charcoal cutout picture., giving it a retro digital appearance mixed with retro handicraft vibes.
