The RuleProcessorY and Gramify tools are new tools that support password-cracking efforts. RuleProcessorY offers a method of optimizing hashcat rule-files so that you can prevent duplicates across multiple attacks better, leading to a shorter runtime. Additionally it can process rules as hashcat would with an additional support for multi-byte/multi-character rules (inserts & replace primarily). Gramify offers an easy method to create base words and candidates to utilize with wordlist and combination attacks by splitting data by words, characters, or character-set. This can help with password phrases, quotes, sentences, combinator attacks, and extracting base-words from passwordlists.
