————MD5 与 SHA-1 已不推荐用于安全场景，仅做校验用途。安全场景请使用 SHA-256 或 SHA-512。
使用说明
- 在输入框粘贴文本，或拖入/选择文件
- 自动计算 MD5、SHA1、SHA256、SHA512 等多种摘要
- 结果实时显示，点击对应行即可复制
- 文本与文件两种模式可切换
常见问题
- 数据处理安全吗？ 哈希计算全部在浏览器本地完成，文件不上传
- 能解密还原吗？ 哈希是单向不可逆，无法从摘要还原原文
- 大文件计算慢？ 采用流式读取，超大文件耗时与体积成正比
补充说明
MD5/SHA1 已不再安全，做完整性校验可用；密码存储与安全场景请用 SHA256 及以上。
