xortool

Uses statistical methods like character equality patterns to guess key length and most frequent chars, reducing manual cryptanalysis effort as shown in the key length guessing examples.

Supports brute-forcing all possible chars (-b) or only printable ones (-o), allowing tailored attacks for different data types, evident in the option descriptions.

Filters decrypted outputs based on predefined sets (e.g., base64) or custom sets via -t flag, helping isolate valid plaintexts efficiently, as demonstrated in the Base64 example.

Enables key recovery using known plaintext snippets with -p option, enhancing attack capabilities without full brute-force, shown in examples with partial plaintext.
