HS512
What this is
HS512 is HMAC-SHA-512. Larger tags, same trust model as HS256. If you needed asymmetric verify, this is not an upgrade — switch families. Symmetric tokens where SHA-512 is mandated. Keep the secret out of browsers.
Open the decoder and paste a HS512 token. Verification stays in the browser.
FAQ
- Is HS512 safer than HS256?
- Against brute force on the hash, marginally. Against a leaked secret, identical. Secret handling dominates.
