解密的密码 [英] decrypted pwd
问题描述
美好的一天！
有一种方法可以检索用户的解密密码，就像我发布了一个SELECT * * FROM pg_shadow;"在早期版本的postgresql中？

如果找到了打破MD5的方式，很多人会非常非常感兴趣。

当然，这是一个简单的方法：
1：生成所有可能密码的列表。
2：为每一个生成一个md5 sig。
3：将无限数量的md5 sig与为
用户存储的sig5 sig进行比较。当它们匹配时，你会得到原始密码，或者至少一个
密码，它将像原版一样工作。
我认为总数这样做所需的计算机时间是几千年的订单，所以可能需要在集群中使用相当大的机器来实现这一点。

这可能是值得的试图花一些时间试图找到一套有限的密码，这些密码被保证成为所有可能的生成器
MD5哈希（或者至少可能发生的哈希） ，这样你就可以在有限的时间内完成计算。

good day!
is there a way to retrieve a user''s decrypted password, just like when i
issued a "SELECT * FROM pg_shadow;" in the earlier version of postgresql?
thanks in advance!ü

If you find a way to break MD5, a lot of people will be very very
interested.

Sure, here''s the simple method:
1: Generate a list of all possible passwords.
2: Generate an md5 sig for each one.
3: Compare your infinite number of md5 sigs to the one stored for the
user. When they match, you''ve got the original password, or at least a
password that will work just like the original.
I think the total computer time required to do this is something on the
order of a few thousand years, so it might take a rather large farm of
machines in a cluster to do this.

It is probably worth trying to spend some time trying to find a finite
set of passwords that are guarenteed to be generators for all possible
MD5 hashes (or at least those than can possibly occur), so that you can
finish the computation in finite time.
