MD5, SHA-1, SHA-2, SHA-3, BLAKE3, CRC32 and more for text or files of any size, plus HMAC and checksum verification – computed locally.
Type text or drop a file and get seventeen checksums at once. Files are hashed in your browser in parallel workers, so even multi-gigabyte ISO images are processed quickly without being uploaded.
Paste a published checksum into Compare to verify a download – the matching algorithm lights up. HMAC with a secret key is one switch away.
