SHA-256 hash
Compute the SHA-256 digest of any text as lowercase hex. Requires a secure context (HTTPS or localhost) for Web Crypto.
What SHA-256 is
SHA-256 is a cryptographic hash: a fixed-length fingerprint of arbitrary input. Small input changes produce very different digests. It is one-way — you cannot recover the original text from the hash.

This page hashes what you paste for convenience. For downloads, compare against a publisher’s published checksum from a trusted channel. Hashes alone do not prove authenticity unless you trust the source of the expected digest.
