本文整理了Java中com.google.common.hash.Hashing.sha1()方法的一些代码示例，展示了Hashing.sha1()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Hashing.sha1()方法的具体详情如下：
包路径：com.google.common.hash.Hashing
类名称：Hashing
方法名：sha1

Hashing.sha1介绍

[英]Returns a hash function implementing the SHA-1 algorithm (160 hash bits).
[中]返回实现SHA-1算法的哈希函数（160个哈希位）。
