Struggling with implementing AES for #cryptopals twice (because I got annoyed at bugs in my code and decided to instead start over using ARMv8 A64 cryptographic instructions like someone would do in a practical and secure modern implementation) has me appreciating AES enough to feel motivated to read most of the historical literature on S-box design and more broadly designing algorithms for avalanche effect
Incidentally the amplification of a small mistake is a lovely illustration of that
Yay. Finally implemented an auto drop function for my rust terminal window manager. It needs to do some termio things to disable echo and other things, which if the program crashes leaves the terminal rather unusable. 'stty echo' is a frequent command...
Or was. Now an assert can panic and the unwinding will restore the terminal state before exit.
A re-run of #cryptopals challenge 30, without a crash, but also no explicit terminal state restoration in code - it "just works".

Решение cryptopals. Часть 3
Завершаем решение cryptopals . В этой части рассмотрим блоки заданий 5 и 6, которые посвящены криптографии с открытым ключом.
Решение cryptopals. Часть 2
Продолжаем решать задания cryptopals . В этой части рассмотрим блоки заданий 3 и 4, которые посвящены блочному шифрованию, хеш-функциям и генераторам псевдослучайных чисел. Первая часть
The third step in Cryptopals needs you to detect English text, specifically the immortal words of poet Vanilla Ice.
I think I’m seriously overthinking this. I’ve got one that works for step 3, but step four is “find the English in these 370-ish lines of ciphertext. And I’m not getting close.
Решение cryptopals. Часть 1
Часто при изучении криптографии делают упор на теорию, оставляя практическую часть в стороне. Упражнения cryptopals — это прекрасный вариант подтянуть практические навыки. С одной стороны, начинать можно с минимумом предварительных знаний. С другой стороны, затронуты все важные темы на примере реальных атак. В этой части рассмотрим блоки заданий 1 и 2.
Got excited this morning and started a new repo for cryptopals.com at https://codeberg.org/Taffer/cryptopals
Going to do Python and C, and try to get better at Go and Rust, and maybe finally learn Ruby.
Odds are I won’t have time to get far, but it’s the thought that counts, right?
Ahh nice. Successfully MITM’d this Diffie-Hellman implementation. I didn’t realize it had such an inherent weakness. Modular exponentiation is fun and weird. Reminder: don’t write your own cryptography #CryptoPals
I was today years old when I learned about "ETAOIN SHRDLU" and cracked the simplest of cyphers. #cryptopals
I think I have a funk-removal plan:
* finish the #Godot 3.x tutorials I bought; they're getting stale
* finish learning #Rust
* tackle #Cryptopals https://cryptopals.com/ using Rust; I've started twice before but always get distracted, maybe trying with a newly-learned language will keep me focused
Also, the usual stuff (#ffxiv, reading, work, family). Could still use 2-3 clones to divide things up...
#cryptopals set 1, challenge 8: I can guess if a ciphertext is AES ECB by looking for repeated blocks.
After breaking encryption of the previous challenges I’d like to break this one too, but I’m not sure where to start nor if it’s even feasible since I don’t have any plaintext/ciphertext pair
Been working my way through set 1 of the Cryptopals challenges as a way of learning Go. Got to challenge 6 and I’m stuck! 4 bytes of my cracked key aren’t right. #crypto #cryptopals #golang
