Hashlib

The runtime exposes a deterministic hashlib module with two helpers:

hashlib.sha256(value)
hashlib.sha3(value)

Input Rules

Both helpers accept a string.

The runtime interprets that string in one of two ways:

• if it is valid hex, it is decoded as bytes first
• otherwise it is UTF-8 encoded as ordinary text

This makes it convenient to hash either textual messages or already-encoded byte-like payloads represented as hex strings.

Output

Both functions return lowercase hex strings.

Common Uses

• deterministic identifiers
• permit or authorization-message hashing
• compact code or config fingerprints
• note, payload, or commitment helper flows in privacy-oriented contracts

Design Guidance

• be explicit about whether callers should pass text or hex
• keep the message format stable before hashing
• do not mix human-readable strings and raw-hex payload conventions casually
