Free Cryptographic Hash Generator — MD5, SHA-256, SHA-512

The Cryptographic Hash Generator computes multiple hash types — MD5, SHA-1, SHA-256, and SHA-512 — from any input text using the Web Crypto API. All hashing is done client-side, so your input never leaves your browser. Useful for integrity checks, API signatures, and learning about hash functions. Free, no account needed.
