SHA-1 可以被解密吗？

不能。与所有密码学哈希函数一样：所谓破解只能靠猜测输入原文，算法函数本身在数学上不可逆向推导。

SHA-1 已经被攻破了吗？

其实际碰撞攻击已经在实践中被攻破。严禁将其用于数字签名或密码存储等安全场景；但用作旧系统中的文件完整性校验码仍然可行。

输入的文本会被上传吗？

不会。Web Crypto 完全在当前标签页内本地运行。

SHA-1 在线哈希

160-bit digest · hashed in this tab

SHA-1 is a one-way hash. There is no decrypt step. The second tab only brute-forces short strings and a tiny local dictionary — it will not reverse a real password hash.
