About This Tool

Hashing is a one-way digest algorithm commonly used for data integrity checks, password storage, and file comparison. This tool supports MD5, SHA-1, SHA-256, and SHA-512 hash algorithms, as well as HMAC signature computation with a custom key. All calculations run locally in the browser.
