What this tool does

Generate a SHA-256, SHA-384, or SHA-512 digest for a short value and compare it with a checksum. The hash is computed locally with the Web Crypto API.

Verify a value without a terminal. Everything runs in your browser; your text is not uploaded.

Good fit

Checking a file checksum, a webhook signature input, or a cache key.

Not a fit

Using a fast hash for password storage or as a substitute for encryption.

Three standard algorithms
