什麼是 雜湊產生器（MD5 / SHA）？
免費線上雜湊產生器，支援 MD5、SHA-1、SHA-256 與 SHA-512。對文字進行雜湊或拖放檔案進行即時校驗。使用 Web Crypto API。
為什麼要使用 雜湊產生器（MD5 / SHA）？
- Four algorithms: MD5, SHA-1, SHA-256, SHA-512
- Text and file hashing with drag-and-drop
- 檔案從不離開瀏覽器 — 完全在本機處理
- Instant real-time hashing as you type
如何使用 雜湊產生器（MD5 / SHA） — 逐步教學
1
Type text to hash or drop a file into the upload area.
2
View all four hash types generated instantly.
3
Click copy next to any hash to copy it.
4
For files, hashes are computed locally without uploading.
雜湊產生器（MD5 / SHA）適合誰？
- 檔案完整性
- 校驗碼驗證
- API 除錯
- 資料去重
雜湊產生器（MD5 / SHA） — 常見問題
Is MD5 secure?
MD5 is considered cryptographically broken and should not be used for security purposes. Use SHA-256 or SHA-512 for security. MD5 is included for legacy compatibility and checksums.
How large a file can I hash?
Files are processed in your browser using the Web Crypto API. Very large files (over 100MB) may take a few seconds but should work fine.
