Introduction📘

The Hash Cracker Tool is a command-line application designed for hash analysis and cracking. It supports multiple hash types (MD5, SHA1, SHA256, SHA384, SHA512) and utilizes multi-threading for efficient processing. This tool is particularly useful for password recovery, security testing, and educational purposes in understanding hash functions and cryptography.

Technical Description⚙️

The Hash Cracker implements several key technical features:

• Hash Type Detection: Automatically identifies hash types based on length:

hash_types = {
    32: "MD5",
    40: "SHA1",
    64: "SHA256",
    96: "SHA384",
    128: "SHA512"
}

• Multi-threaded Processing: Utilizes Python's concurrent.futures for parallel processing:

with concurrent.futures.ThreadPoolExecutor(max_workers=args.threads) as executor:
    future_to_hash = {executor.submit(cracker.crack_hash, h): h for h in hashes}

• Rate Limiting: Implements a custom rate limiter to prevent service overload:

class RateLimiter:
    def __init__(self, calls: int, period: float):
        self.calls = calls
        self.period = period
        self.timestamps = []
