philiprehberger-hash-utils

Simplified hashing helpers for strings, files, and checksums.

Installation

pip install philiprehberger-hash-utils

Usage

Hash Strings and Bytes

from philiprehberger_hash_utils import hash_string, hash_bytes

hash_string("hello world")                # SHA-256 hex digest
hash_string("hello world", "md5")         # MD5 hex digest
hash_bytes(b"\x00\x01\x02", "sha512")    # SHA-512 hex digest

Hash Files

from philiprehberger_hash_utils import hash_file

digest = hash_file("large_file.bin")  # Streams in chunks
digest = hash_file("data.csv", algorithm="blake2b")

Hash Dictionaries

from philiprehberger_hash_utils import hash_dict

# Deterministic — key order doesn't matter
hash_dict({"b": 2, "a": 1}) == hash_dict({"a": 1, "b": 2})  # True

Verify Checksums

from philiprehberger_hash_utils import verify_checksum

# Timing-safe comparison
is_valid = verify_checksum("download.zip", expected_sha256)

Supported Algorithms

md5, sha1, sha256 (default), sha512, blake2b

API

• hash_string(s, algorithm="sha256") — Hash a string
• hash_bytes(data, algorithm="sha256") — Hash raw bytes
• hash_file(path, algorithm="sha256", chunk_size=8192) — Hash a file (streaming)
• hash_dict(d, algorithm="sha256") — Deterministic dict hash
• verify_checksum(path, expected, algorithm="sha256") — Timing-safe file verification

Development

pip install -e .
python -m pytest tests/ -v
