Hash Generator
Generate MD5, SHA-1, SHA-256 and SHA-512 hashes from text or files. Everything runs in your browser.
What is a hash function?
A hash function takes an input of any size and produces a fixed-size digest. The same input always produces the same output, but even a tiny change produces a completely different hash. Useful for verifying data integrity, storing passwords, and generating checksums.
Is this hash generator secure?
SHA-1, SHA-256 and SHA-512 are computed using the browser's built-in crypto.subtle Web Crypto API. MD5 uses a pure JS implementation. All computation happens locally — no input text or file data is sent to any server.
