🔑 Hash Generator

Generate cryptographic hashes using the browser's built-in Web Crypto API. No data leaves your device.

About Hash Generator

Cryptographic hash functions like MD5, SHA-1, SHA-256, and SHA-512 turn any input into a fixed-length fingerprint that uniquely represents the data. This generator creates them instantly using your browser's built-in Web Crypto API, so your text or file data never leaves your device. Hashes are used to verify file integrity, store passwords securely, and create checksums.

Type or paste any text to see all hash values side by side, or upload a file to generate its hash and verify it matches a known checksum. Handy for developers, sysadmins, and security professionals who need to confirm a downloaded file hasn't been tampered with, or verify that two files are identical without comparing them byte by byte.
