WebOct 21, 2024 · This challenge asks us to detect whether we’ve encrypted a text with ECB or CBC, chosen at random. Recall the properties of ECB vs CBC — ECB will take two identical plaintext blocks and produce two identical ciphertext blocks. So just detect ECB using the function in challenge 8. If it's ECB, return ECB. If not, return CBC 2.12. WebDec 23, 2024 · Since starting a new job as a security engineer, I’ve been working my way through the Cryptopals Challenges. In this post I’ll be taking a look at Set 1 Challenge 2. The Problem. In challenge 2 we are given two hex encoded strings of equal length. We need to decode these strings, get their XOR combinations, and then hex encode the result. nothing gained

WebAug 15, 2024 · I am aware of how i would go about doing this (without looking solutions): 1) convert the string to binary 2) loop through all character values XORing them individually with the given ciphertext 3) checking these XORd results to see which one looks "the most english". I guess im just confused on the way bytes behave in python. here is my code:
