在密码学中,SHA-1(Secure Hash Algorithm 1)是一种加密哈希函数,它接受一个输入,并产生一个160位(20字节)的哈希值,称为信息摘要。 我们先看下SHA1的加密流程图: 上面的A,B,C,D,E都是32bits的state。 F是一个非线性函数。 <<< 表示额是左移操作,红色的加号表示的是加法然后对232取模。

SHA1 is a cryptographic hash function. It's result is usually expressed as a 160 bit hex number. SHA1 was developed by the NSA. SHA1 is widely considered the successor to MD5. If you want to learn all about SHA1, lookhere.
