The Hash Generator turns any text into its cryptographic fingerprint - a fixed-length digest that changes completely if even one character changes. It computes MD5, SHA-1, SHA-256, SHA-384 and SHA-512 all at once: the SHA family via your browser's built-in WebCrypto, MD5 via a compact standards-compliant implementation, since browsers no longer ship MD5. New: HMAC mode signs text with your secret key (HMAC-SHA-256/512, e.g. for webhook signature debugging), and an expected-hash field gives a green Match / red Mismatch verdict.

Hashes are perfect for checksums, cache keys, Gravatar URLs and verifying file integrity. Everything is computed on your device - your input is never uploaded or stored. You get 5 free generations with no account - IconVault Pro ($12/year) unlocks unlimited hashing and every other tool on the platform.
