SHA-256 / SHA-512 Hash Generator (Web Crypto)
Compute cryptographic hashes using your browser's hardware-accelerated native crypto implementation — not a hand-rolled JS hash. Ideal for verifying file checksums, generating API signatures, and comparing content.
Hashing happens locally; nothing is transmitted.
