SHA256错误识别

问题描述

我试图在下面识别这个哈希码几个小时：

$6$VQoztKJH$0aL8rygMd8gfX7m8cTRWOn4pqQ6bA/jkPyQSnzU0g10E0UiMQjIijs/66vflY7cMrGSKmmiBWE7r8oNCDQc3D/

不，它不是 sh-2 也不是 sha256。

它可能是一个身份不明的人吗？

解决方法

$6 表示哈希来自 SHA-512 算法，参见 man 3 crypt：

   If salt is a character string starting with the characters "$id$"
   followed by a string optionally terminated by "$",then the
   result has the form:

          $id$salt$encrypted

   id identifies the encryption method used instead of DES and this
   then determines how the rest of the password string is
   interpreted.  The following values of id are supported:

          ID  | Method
          ─────────────────────────────────────────────────────────
          1   | MD5
          2a  | Blowfish (not in mainline glibc; added in some
              | Linux distributions)
          5   | SHA-256 (since glibc 2.7)
          6   | SHA-512 (since glibc 2.7)
