**SHA**

安全散列算法。**SHA** 分为 **SHA1** 和 **SH2** 两个版本。该算法的思想是接收一段明文，然后以一种不可逆的方式将它转换成一段（通常更小）密文，也可以简单的理解为取一串输入码（称为预映射或信息），并把它们转化为长度较短、位数固定的输出序列即散列值（也称为信息摘要或信息认证代码）的过程。
安全散列算法。**SHA** 包括**SHA-1**、**SHA-2**和**SHA-3**三个版本。该算法的基本思想是：接收一段明文数据，通过不可逆的方式将其转换为固定长度的密文。简单来说，SHA将输入数据（即预映射或消息）转化为固定长度、较短的输出值，称为散列值（或信息摘要、信息认证码）。SHA-1已被证明不够安全，因此逐渐被SHA-2取代，而SHA-3则作为SHA系列的最新版本，采用不同的结构（Keccak算法）提供更高的安全性和灵活性。
