[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?

Rhizome Function Anagram Random Generator

preprint | https://zenodo.org/records/21551292

doi | https://orcid.org/0009-0009-5144-3278

Herein are described principles and a scheme of random number generation styled as, pangrandomonium, or ‘pangrand’. Pangrand is a anagrammatic random number generator that uses rhizome functions as chaotic indexing and shuffling instructions to reorder and sum perfect pangrams. Brief descriptions are given for the principles of pangram summing and rhizome indexing functions, Source code of the random number generator is included herewith. The source code is attached to the PDF file.

Sections:

1. Pangrams (Holoalphabetic arrays) ;
2. Rhizome Functions ;
3. Rhizome Hardness Problems ;
4. Random Generator Methods ;
5. Errata ;
6. Source Code.

A pangram is a sentence or phrase that contains each letter of an alphabet or character set at least once. A perfect pangram is an anagram of the alphabet which contains each letter exactly once.

Pangram hash generates a perfect pangram hash digest consisting of a anagram permutation of a character set. Each character in the output is unique and non-repeating.

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.
