UnverifiedSHA-1（Secure Hash Algorithm 1）由美国国家安全局设计，输入任意长度数据输出固定160位（40个十六进制字符）的哈希值74% similarUnverifiedCommit SHA 基于 SHA-1 的内容寻址特性，具备密码学层面的完整性保证，即便标签被恶意篡改，锁定 SHA 的工作流也不会受影响，Git 正逐步向 SHA-256 迁移71% similarUnverified数字签名工程实现中通常先计算消息的密码学哈希（如 SHA-256）再对哈希值签名，因为非对称加密运算开销远大于哈希运算68% similarUnverifiedk-匿名（k-anonymity）技术将用户密码进行 SHA-1 哈希后仅发送哈希值前 5 个字符到服务端进行前缀匹配，客户端在本地完成完整比对，从而不暴露实际密码或完整哈希66% similar
