About Hash Generator
Last updated: May 2026
OptiPix Hash Generator 直接在您的浏览器中计算文本或文件的加密哈希值。输入文本或拖放文件，即可立即同时生成 MD5、SHA-1、SHA-256、SHA-384 和 SHA-512 哈希值。在小写十六进制、大写十六进制和 Base64 输出格式之间切换。使用带密钥的 HMAC 模式来生成密钥哈希消息认证码。哈希比较工具可让您粘贴两个哈希值以验证它们是否匹配 - 非常适合文件完整性验证。键入时哈希值会实时更新。SHA 哈希使用内置于每个现代浏览器中的 Web Crypto API；MD5 使用捆绑的纯 JavaScript 实现。没有任何内容会发送到任何服务器。
How It Works
SHA 哈希使用 Web Crypto API 的 crypto.subtle.digest() 方法，该方法内置于每个现代浏览器中。MD5 使用捆绑的纯 JavaScript 实现，因为 Web Crypto API 不支持 MD5。对于 HMAC，该工具使用 crypto.subtle.sign() 和 HMAC 算法。
Use Cases
- •下载后验证文件完整性
- •生成校验和以进行数据验证
- •为 API 身份验证创建 HMAC 签名
- •比较哈希值以检测文件修改
- •生成哈希摘要以用于密码存储研究
