Hash Algorithm Inspector

Name: tessl/pypi-xxhash
Author: tessl

Build a utility that inspects and compares different hash algorithms by examining their properties and characteristics.

Capabilities

Hash Algorithm Information Reporting

Calling get_algorithm_info("xxh32") returns a dictionary with keys 'name', 'digest_size', and 'block_size' with correct values @test
Calling inspect_multiple_algorithms(["xxh32", "xxh64"]) returns a dictionary with two entries, each containing the algorithm's properties @test

Seed Verification

Calling verify_seed("xxh64", 12345) returns a dictionary with 'algorithm', 'seed', and 'matches' keys, where 'seed' is 12345 and 'matches' is True @test

Algorithm Comparison

Calling compare_algorithms("xxh32", "xxh64") returns a dictionary identifying "xxh64" as having the larger digest size @test

Implementation

@generates

API

def get_algorithm_info(algorithm_name: str) -> dict:
    """
    Get information about a hash algorithm.

    Args:
        algorithm_name: Name of the hash algorithm (e.g., "xxh32", "xxh64")

    Returns:
        Dictionary containing:
        - 'name': algorithm name
        - 'digest_size': size of hash output in bytes
        - 'block_size': internal block size in bytes
    """
    pass

def inspect_multiple_algorithms(algorithm_names: list) -> dict:
    """
    Inspect multiple hash algorithms and return their properties.

    Args:
        algorithm_names: List of algorithm names to inspect

    Returns:
        Dictionary mapping algorithm names to their info dictionaries
    """
    pass

def verify_seed(algorithm_name: str, seed: int) -> dict:
    """
    Create a hasher with a specific seed and verify the seed property.

    Args:
        algorithm_name: Name of the hash algorithm
        seed: Seed value to use

    Returns:
        Dictionary containing:
        - 'algorithm': algorithm name
        - 'seed': the seed value from the hasher's seed property
        - 'matches': boolean indicating if seed matches expected value
    """
    pass

def compare_algorithms(algo1: str, algo2: str) -> dict:
    """
    Compare two hash algorithms based on their properties.

    Args:
        algo1: First algorithm name
        algo2: Second algorithm name

    Returns:
        Dictionary containing:
        - 'larger_digest': name of algorithm with larger digest_size
        - 'larger_block': name of algorithm with larger block_size
        - 'algo1_info': info dict for first algorithm
        - 'algo2_info': info dict for second algorithm
    """
