Question

我有一个包含哈希的文件，我需要做的是将所有特定哈希与正则表达式匹配，如果有更简单的方法请详细说明，但是这个文件包含多种不同类型的哈希：

请注意，散列类型仅在此文件中用于测试目的，散列类型不在文件中

我已经为MD5提出了这个正则表达式：([a-fA-F\d]{32,40})这是有效的，但它也匹配几乎一半的SHA哈希值，例如：

ae696df69ec720fbb46d52ebbc262fc8 #<= match
369ee30df7b4b261d5dcd5b607ffca17 #<= match
d0351496ef238247ccba08518f10678a <= match continue hash => 6211080a98a6128fa49bd225a2bbec360e3e1b93759f68c14ae3b95096fd81682c1f4a1453
e0057af4a55a910d3066b2

有没有办法可以匹配仅 MD哈希值（md4，md5），以及仅 SHA哈希值{{1 }，sha512，sha384等等。）？

Answer 1

你可以依靠正则表达式中的OR符号|来捕捉你需要的东西。这仅在哈希值具有特定长度时才有效。根据@ chris85评论，我们可以使用sha512进一步添加sha384和|，方法是指定例如sha512只有{52,60}个字符，而sha384只有{92,100}个字符，等等。它将是这样的：

^(?:[a-fA-F\d]{32,40})$|^(?:[a-fA-F\d]{52,60})$|^(?:[a-fA-F\d]{92,100})$

演示：https://regex101.com/r/z5SoCS/1

您可以使用组进一步增强正则表达式，并为每个哈希指定名称。例如，您可以执行以下操作：

^(?<sha384>[a-fA-F\d]{92,100})$

Answer 2

您无法通过检查输出来告诉创建哈希的哈希算法。

问题中的所有哈希值都以十六进制表示，因此无法通过其内容告知创建的哈希值。

可以做的最好的事情是查看长度，但会有几个哈希可以创建一个特定的长度。

如果您需要知道哈希，则需要以某种方式对哈希进行编码，例如前缀。
