summary
A small Go CLI decodes a hex string, tries all 256 keys with single-byte XOR brute force, scores each candidate by summing English-letter weights, and picks the top result. Implementation uses Go functions to decode hex, map byte→frequency, and loop keys; it runs with go run main.go. The highest-scoring output reads "Welcome to KubeCon + Cloud Native North America 2021", so the brute force plus frequency scoring using ETAOINSRDLU approach successfully recovers the plaintext.
