Orchard Street Long 17,576 Orchard Street Wordlists are a collection of English word lists designed for generating strong, secure passphrases. The words are primarily sourced from Google Books Ngram data and Wikipedia, filtered to exclude profanity, abbreviations, and British spellings, and processed using Schlinkert pruning to ensure they are uniquely decodable (allowing passphrases without delimiters). Orchard Street Medium 8,192 A smaller set than the long version, with shorter maximum word length.

Larger word lists increase the total number of possible combinations for a given word count, which improves strength. In contrast, EFF Easy Short and EFF Easy Long are smaller sets but also the easiest — they use familiar English words chosen to minimize confusion between similar-sounding entries.

A word list file must be UTF-8 encoded with a .wordlist extension, one word per line. Lines beginning with ### are treated as comments and skipped.
