Why verify file hashes?
A cryptographic hash is a fixed-length fingerprint of a file's contents. SHA-256 and SHA-512 are part of the SHA-2 family and are widely used to verify file integrity — if even one byte changes, the hash changes completely. Compare the hash you compute here against the checksum published by a software vendor to confirm a download is genuine and wasn't tampered with in transit. SHA-1 is included for legacy compatibility (it is no longer considered secure for cryptographic signing). All hashing runs in your browser using the Web Crypto API — your file is never sent anywhere. For text hashing, try Hash Generator.
