Vb.net解密sha512哈希 [英] Vb.net Decrypt sha512 hash

问题描述

我正在努力解密哈希我的 sha512 加密。我正在寻找一种方法来解密它。

顺便说一下，我是如何进行加密的：

  Dim uEncode As New UTF8Encoding（）
 Dim bytClearString（）As Byte = uEncode.GetBytes（to encrypt）
 Dim sha As New _ 
 System.Security.Cryptography.SHA512Managed 
 Dim WordEncrypt As String =
 Dim hash（）As Byte = sha.ComputeHash（bytClearString）
对于每个b作为字节在散列
 WordEncrypt& = b.ToString（x2）
下一个
  

我需要什么现在要知道如何解密它。

解决方案

SHA512不是加密算法，它是一个散列算法。这意味着无法从生成的哈希中恢复出现的数据。

我很抱歉，但是没有办法使用彩虹表风格查找以获取原始数据。在这里有一个在这里的不同之处。

Heys guys,

I'm struggling about out to decrypt the hash how my sha512 encryption. I'm searching a way to finnaly decrypt it.

By the way this is how I do the encryption:

Dim uEncode As New UTF8Encoding()
        Dim bytClearString() As Byte = uEncode.GetBytes("to encrypt")
        Dim sha As New  _
        System.Security.Cryptography.SHA512Managed
        Dim WordEncrypt As String = ""
        Dim hash() As Byte = sha.ComputeHash(bytClearString)
        For Each b As Byte In hash
            WordEncrypt &= b.ToString("x2")
        Next

What i need now is to know how to decrypt it.

解决方案

SHA512 is not an encryption algorithm, it's a hashing algorithm. What this means is that the data that goes into it cannot be recovered from the generated hash.

I'm sorry but there is no way short of using a rainbow table style lookup to get the original data back. There's a great post on the difference here on SO.
