About this tool

Get MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC32 of a text or of a file you drop in, as hex or Base64. Add a key for HMAC signatures – for example to check a GitHub webhook's X-Hub-Signature-256 – compare a digest with the checksum you expect, and identify an unknown hash by its format.

Files are read locally and never uploaded.
