Generate precomputed hash tables from large wordlists. Precompute hash:password
pairs for fast reverse searches. Designed for security research and password analysis.
This tool is intended for:
- Educational purposes
- Legitimate security research
- Auditing your own systems/passwords
By using this software, you agree:
- Never to use it on systems/data without explicit ownership or permission
- Password hashtables may contain sensitive information – do not share generated files
- You are solely responsible for complying with laws (e.g., GDPR, CFAA) in your jurisdiction
- Modern secure systems use "salted hashes" – this tool will not work against properly secured passwords
Illegal uses include (but are not limited to):
- Bypassing authentication mechanisms
- Distributing password lists without consent
- Accessing accounts/systems you don’t own
The developer assumes no liability for misuse. Security tools can be weapons – use responsibly.
Converts a wordlist (list of passwords) into a file of [hash]:[password]
pairs. For example:
Input File (500-worst-passwords.txt
):
12345
dragon
qwerty
696969
mustang
letmein
Output File (500-worst-passwords-sha1-hashtable.txt
):

- Services like CrackStation and Weakpass use giant hashtables to instantly find passwords for stolen hashes.
- Without a hashtable, cracking takes hours/days. With it, common passwords are found in seconds.
- Hashing is slow. This tool does the work upfront so lookups take zero time later.

Weakpass.com, CrackStation, etc., use multi-billion-entry hashtables. They use a tool like this to generate them. You give them a hash → they check their precomputed list → instantly return the password if it exists.
