Hash & HMAC Generator

Hash UTF-8 text or file bytes with the browser Web Crypto API. Empty text is a valid input. HMAC keys are entered manually.

Available algorithms are SHA-1, SHA-256, SHA-384, and SHA-512. SHA-1 is for legacy checksums, not security. MD5, SHA-3, RIPEMD-160, and Whirlpool are not provided by Web Crypto.

Agent tools require a browser with WebMCP support. You can use this tool manually.
