🔐 Python Hash Cracker
A fast, multiprocessing brute-force hash-cracking tool written in Python. Supports multiple hashing algorithms, multiple character sets, real-time progress reporting, and efficient search-space generation.
🚀 Features
🔥 Brute-force cracking with multiprocessing
🔣 15 customizable character sets (letters, digits, punctuation, mixed variants)
🧮 Supports major hashing algorithms:
MD5, MD4, LM, NTLM
SHA-1, SHA-224, SHA-256, SHA-384, SHA-512
⏱️ Real-time progress output: iterations, hashes/sec, latest candidate
💾 Efficient memory usage: generates combinations on the fly
🔧 Automatic UTF-8 / UTF-16LE encoding based on hash type
✔️ Fully interactive CLI tool
📦 Requirements
Python 3.x
No external dependencies (uses only Python standard library)
📁 Installation
Clone the repository:
git clone https://github.com/your-username/hash-cracker.git cd hash-cracker
Make the script executable:
chmod +x cracker.py
Run:
./cracker.py
Or:
python3 cracker.py
When running the tool, you'll be prompted for:
-
Character Set
-
Maximum Password Length
-
Hash Type
-
Hash Value
Example:
Specify the character set to use:
- abcdefghijklmnopqrstuvwxyz
- ABCDEFGHIJKLMNOPQRSTUVWXYZ
- abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ ...
Specify the maximum possible length of the password: 5
Specify the hash's type:
- MD5
- MD4 ...
Specify the hash to be attacked: 5d41402abc4b2a76b9719d911017c592 Trying to crack hash 5d41402abc4b2a76b9719d911017c592
Example output:
Character set: abcdef..., iteration: 5120, trying: hell, hashes/sec: 1024 Match found! Password is hello
Took 3.21 seconds
🧠 How It Works
Generates combinations using itertools.product
Hashes each candidate string
Compares the result to the target hash
Uses multiprocessing to split workloads across character-set partitions
Reports progress at timed intervals
Stops all processes when the password is found

📊 Performance Notes
Brute-forcing is exponential and extremely intensive
Long passwords and large character sets take significantly longer
Use maximum password length and character sets wisely
CPU speed directly affects cracking performance
