A fast, multi-threaded hash cracking tool written in Rust. This tool performs dictionary attacks against hashed passwords.

• Single hash cracking: Crack individual hashes
• Batch TXT processing: Crack multiple hashes from a text file (one hash per line)
• Batch CSV processing: Crack hashes from CSV files with customizable column mapping
• Multi-threaded: Leverages all CPU cores for faster cracking
• Multiple algorithms: Supports MD5, SHA1, and SHA256

• Rust (1.70+)

cargo build --release
./target/release/crack-hash --help

Or directly with Cargo:

cargo run --release -- --help

If you prefer using Docker:

docker compose build

docker compose up -d
docker compose exec crack-hash bash

# Inside the container
cargo build
cargo run -- --help

Note: All examples below use cargo run --. After building with cargo build --release, you can use ./target/release/crack-hash directly.

Crack a single hash:

cargo run -- single -a <ALGORITHM> -H <HASH> -w <WORDLIST>

Example:

cargo run -- single -a md5 -H 5d41402abc4b2a76b9719d911017c592 -w wordlist.txt

Crack multiple hashes from a text file (one hash per line):

cargo run -- batch-txt -a <ALGORITHM> -i <INPUT_FILE> -o <OUTPUT_FILE> -w <WORDLIST>

Example:

cargo run -- batch-txt -a md5 -i hashes.txt -o results.txt -w wordlist.txt

Crack hashes from a CSV file with customizable format:

cargo run -- batch-csv -a <ALGORITHM> -i <INPUT_CSV> -o <OUTPUT_CSV> -w <WORDLIST> [OPTIONS]

Example with header:

cargo run -- batch-csv -a sha256 -i users.csv -o cracked.csv -w wordlist.txt -c 2

Example without header:

cargo run -- batch-csv -a md5 -i data.csv -o results.csv -w wordlist.txt -c 1 --no-header

Example with custom delimiter (semicolon):

cargo run -- batch-csv -a md5 -i data.csv -o results.csv -w wordlist.txt -d ";"

• MD5
