Complete Guide to the Openwall Wordlists Collection: What’s Inside and How to Use It

Quick Reference: High-Value Wordlists from the Openwall Collection

What it is

A concise guide highlighting the most useful wordlists in the Openwall wordlists collection—precompiled lists of passwords, usernames, and candidate strings widely used for password auditing, penetration testing, and research.

Who it’s for

• Security testers conducting offline password audits
• Red-teamers and penetration testers
• System administrators verifying password policy strength
• Researchers studying password distributions and user behavior

High-value wordlists (not exhaustive)

• passwords/top-10-million.txt — Massive list of common passwords compiled from breaches; high recall for weak-password detection.
• passwords/rockyou-etc.txt — Variants and aggregates related to the well-known rockyou list; useful for broad coverage.
• passwords/more_common_passwords.txt — Smaller curated list ideal for quick checks and CI integration.
• usernames/common-usernames.txt — Common username candidates for user-enumeration and targeted guessing.
• mangled/wordmangling.txt — Pre-mangled entries and mutation patterns to simulate common password-creation behaviors.

When to use which

• Quick scans and CI: use more_common_passwords.txt for speed with decent coverage.
• Deep offline cracking: use top-10-million.txt combined with mangling rules.
• Targeted assessment: combine common-usernames.txt with a focused password subset and targeted mangling.
• Research: use full aggregated sets to analyze frequency and patterns.

Practical tips

• Combine lists with rule-based mangling (hashcat/john) rather than relying solely on raw entries.
• De-duplicate and sort by frequency when merging multiple lists to improve efficiency.
• Prefer smaller curated lists for automated checks to reduce false positives and runtime.
• Keep legal/ethical constraints in mind—only test systems you have permission to evaluate.

Quick workflow example

1. Select base list: start with more_common_passwords.txt.
2. Apply mangling rules: append common suffixes, leet substitutions, and capitalization.
3. Run low-cost checks in CI; escalate to larger lists only for authorized deep assessments.
4. Log results and prioritize remediation for reused or easily guessed passwords.
