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.

        Syfer Sangraal : Holy Grail of Cryptography in the Arc of the Combinant

        https://doi.org/10.5281/zenodo.22158384

        Embark on the quest for the Syfer Sangraal system, or the holy grail of cryptography hidden in the arc of the combinant. The Holy Grail of Cryptography is a single, simple algorithm that performs all necessary functions of computational cryptography with provable security sans assumptions in the model. One system to roll them all is the holy grail of cryptography. One algorithm to perform every kind of cryptographic function is the new wine within the Syfer Sangraal system.

              NEWSCARD: Decentralized, Encrypted Paste Bin via Usenet Newsgroups

              NEWSCARD Publish and fetch permanent named records via Network News

              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.
