Hm. Binary nybbles with an abnormally high number of 7s, no 2s or 0s, across like 13k bits…

What could it be? #Cryptography #Cryptanalysis

Raspberry Pi is overpowered! Hosting discord bots for free is so awesome

One other thing I spent too much time on: interpreting decoded base64 binary in n-grams, converting to a number (quarternary in my case), and then using trigrams of that number to do a base64 index lookup… RESULTS IN THE ORIGINAL BASE64 STRING!! 🤦🏻‍♂️ #Cryptography

A cool encoding mechanic I found today (security through obscurity):

You can encode a message to base64 and then execute the following steps:

- reverse
- decode
- encode to hex
- reverse
- decode
- encode to base64
- …

Entropy stays fairly stable too! #Cryptography

Recent experiments with our classical cipher masked as a base64 encoded string:
- XOR with provided key? Nope.
- input/output diff? Nope.
- Binary -> DNA sequence? Nada.
- Trifid? Perhaps, but perhaps… not!
- custom hill? … pending

Security through obscurity is tough. #Cryptography

Hey #ATProtocol enthusiasts. I’m shopping to get out of centralized platforms. I’ve found alternatives like PinkSky for Instagram and Bluescreen for TikTok. These platforms feel redundant—same feeds/content as BlueSky!

What am I missing?

Ok new cipher. This one is particularly tricky. Base64, known classical technique used, but not sure which. Doesn’t decode to anything meaningful. Perhaps the message is encoded through shorter than 8 or 6 bit sequences?

I have so many positive things to say about #AugmentedReality as the final frontier. I would love a world where ads of all kinds were projected rather than actually present. I could remove my glasses and enjoy a pristine environment. Ad free!

A decentralized protocol for… the physical world 🤔

Have a write-up in the works. Tonight I’ve been working on a beam search with NLTK log probability scoring to construct cribs. Unfortunately the iterative approach is converging on the n-1 words, so results are not diverse at all. Taking a crack at something to fix this.

Today’s progress on the cipher is… interesting. I’m trying to generate cribtexts using only known word lengths and a massive dictionary. Crazy number of permutations, so attempting beam search with NLTK to score grammar.

I am developing a cryptanalysis dashboard that lets you build a “fingerprint” for your ciphers. It’s a great way to measure their difficulty, try and find weaknesses, and more! Comes with docs as well. Fun for classical #cryptography. Can graph tons of metrics/analysis across many ciphertexts.

Been working on this old classical cipher that’s gone unsolved for about 9 years now. Current hypothesis is it’s a Quagmire III (Vigenere autokey with custom alphabet). Working through some possible ways to search the solution space.
