WebAug 28, 2024 · We recently started working on the cryptopals crypto challenges in Python 3, coming in with zero cryptography knowledge. Here are some notes on our thought process while solving Set 1, along with our solutions. Don’t read this if you want to try them out too. Challenge 1: Convert hex to base64 ¶ WebThe general solution to this challenge is to xor the cipher text with each possible key ( all letters between a-z) score the resulting plaintext as per the expected character frequency and the plaintext with the best score is the winner. I had an alternative solution as described below: Build a frequency table on the cipher text. tsi charge
