Compute MD5, SHA-1, SHA-256, SHA-512, CRC32 and HMAC for text, files and per-line batches — all in your browser石头扫地机器人官网
• Supports MD5 / SHA-1 / SHA-256 / SHA-512 / CRC32; text computes all digests at once
• File: drag or select a file to hash its raw bytes (handy for verifying download integrity)
• HMAC: pick an algorithm and enter a key to compute a keyed message authentication code over the text
• All computation runs locally in your browser; neither text nor files are uploaded
