Hash Generator哈希值生成

Generate MD5, SHA-1, SHA-256 or SHA-512 hashes.

用 MD5、SHA-1、SHA-256 或 SHA-512 为文本生成哈希值，常用于校验与签名。

What is Hash Generator?哈希值生成 是什么？

A hash generator produces a fixed-length fingerprint of any text or file using MD5, SHA-1, SHA-256 or SHA-512. Hashes verify file integrity, compare documents, and store password-derived checksums. SHA-256 and SHA-512 are computed with the browser built-in Web Crypto API; MD5 is included because legacy systems still expect it. Nothing you type is ever transmitted.

哈希生成器用 MD5、SHA-1、SHA-256 或 SHA-512 为任意文本或文件生成固定长度的指纹。哈希用于校验文件完整性、比对文档、生成缓存键与变更检测。SHA-256/SHA-512 使用浏览器内置 Web Crypto 计算，MD5 因遗留系统仍在用而保留。输入内容不会被传输。

How to use hash generator如何使用 哈希值生成

1. Type or paste the text, or drop a file into the input to hash its contents.
2. Pick an algorithm: MD5, SHA-1, SHA-256 or SHA-512.
3. Read the digest. SHA-256 and SHA-512 are recommended for anything security related.
4. Copy the hex string. All algorithms run locally, so sensitive input never leaves the page.

1. 输入或粘贴文本，或把文件拖进输入框对其内容做哈希。
2. 选择算法：MD5、SHA-1、SHA-256 或 SHA-512。
3. 读取摘要。涉及安全请用 SHA-256 或 SHA-512。
4. 复制十六进制结果。所有算法本地运行，敏感输入不离开页面。

Common uses常见用途

• Verify that a downloaded file matches the checksum published by its author
• Compare two documents for equality without reading them line by line
• Generate a short fingerprint for cache keys, deduplication or change detection
• Check legacy MD5 values still required by older systems and databases

• 校验下载文件与作者公布的校验和是否一致
• 不逐行阅读就判断两份文档是否相同
• 为缓存键、去重、变更检测生成短指纹
• 生成老旧系统和数据库仍要求的 MD5 值
