About this tool

Uses the browser's SubtleCrypto.digestAPI. MD5 is not offered because it's broken for security uses and is not part of Web Crypto.

Verifying a download? Paste in the published checksum and use the inline comparison — it does a constant-character match so you don't need to eyeball 64 hex chars.

Frequently asked

▸Which algorithm should I use?

SHA-256 is the default for almost everything: checksums, fingerprints, content-addressed identifiers. Use SHA-512 only if you're following a specific spec that requires it. Avoid SHA-1 — see below.

▸Is SHA-1 still safe?

Not for security. SHA-1 has been broken in practice — researchers have produced collisions. It's still fine for non-security fingerprints (Git uses it for object IDs), but never use SHA-1 for signatures, passwords, or anything an attacker could try to forge.

▸How is this different from HMAC?

A plain hash takes one input. HMAC takes a message AND a secret key, and is the right primitive for authenticating messages or signing webhook payloads. BEAD has a dedicated HMAC Calculator.
