altrepo-hash

AltRepo Hash is a lightweight Python utility library for generating hashes and verifying checksums for text, bytes, and files.

Features

• Straightforward API: Easily generate hashes or verify checksums with a clean, intuitive interface.
• Zero Dependencies: Built entirely on top of Python's standard library, ensuring a lightweight footprint with no external requirements.
• Secure Verifications: Utilizes constant-time comparisons (hmac.compare_digest) to securely verify file and text hashes.
• Broad Algorithm Support: Includes built-in support for all major hashing algorithms including sha256, sha512, sha3_256, blake2b, blake2s, md5, sha1, and more.
• Memory Efficient: Safely processes large files in chunks via hash_file without loading the entire file into memory.

Example API

from altrepo_hash import hash_text, hash_file, verify_file_hash

print(hash_text("hello", algorithm="sha256"))

print(hash_file("download.zip", algorithm="sha256"))

print(
    verify_file_hash(
        "download.zip",
        expected_hash="abc123...",
        algorithm="sha256"
    )
)
