# hashtable
Generate precomputed hash tables from large wordlists. Precompute `hash:password` pairs for fast reverse searches. Designed for security research and password analysis.
## ⚠️ DISCLAIMER
**This tool is intended for:**
- Educational purposes
- Legitimate security research
- Auditing **your own** systems/passwords
**By using this software, you agree:**
1. **Never** to use it on systems/data without **explicit ownership or permission**
2. Password hashtables may contain sensitive information – **do not share** generated files
3. **You are solely responsible** for complying with laws (e.g., GDPR, CFAA) in your jurisdiction
4. 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.
## What Does This Do?
Converts a wordlist (list of passwords) into a file of `[hash]:[password]` pairs. For example:
**Input File ([`500-worst-passwords.txt`](https://github.com/ibnaleem/hashtable/blob/main/examples/500-worst-passwords.txt))**:
```
12345
dragon
qwerty
696969
mustang
letmein
```
**Output File ([`500-worst-passwords-sha1-hashtable.txt`](https://github.com/ibnaleem/hashtable/blob/main/examples/500-worst-passwords-sha1-hashtable.txt))**:

## Why Use This?
### 1. **Instant Password Lookups**
- Services like [CrackStation](https://crackstation.net/) and [Weakpass](https://weakpass.com) 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**.
### 2. **Save Time**
- Hashing is slow. This tool does the work upfront so lookups take **zero time** later.
## How to Use
```bash
$ git clone https://github.com/ibnaleem/hashtable.git # Linux
$ cd hashtable
$ python3 hashtable -h
usage: Hashtable Generator [-h] -w WORDLIST -m HASHTYPE
Generate precomputed hashtables (hash:pass) from a wordlist
options:
-h, --help show this help message and exit
-w, --wordlist WORDLIST
The wordlist to create a hashtable of
-m, --hashtype HASHTYPE
the hashtype to use for the hashtable

Supported Hashes: `md5`, `sha1`, `sha256`, `sha512`. If you would like more hashing algorithms, please open a PR.
## How Websites Use This
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.
