Module hash 

Password hashing and digest helpers.

Passwords are hashed with Argon2 and a fresh salt for storage, while SHA-256 helpers cover the deterministic digest cases used by services. The module keeps formatting helpers centralized so hex output stays lowercase and stable across call sites.

Functions

bytes_to_hex

Encodes arbitrary bytes as lowercase hex.

hash_password

Hashes a password with Argon2 and a fresh random salt.

new_sha256

Creates a new incremental SHA-256 hasher.

sha256_digest_to_hex

Encodes a SHA-256 digest as lowercase hex.

sha256_hex

Computes the SHA-256 digest of data and returns lowercase hex.

verify_password

Verifies a password against a stored Argon2 password hash.
