MD5到文本转换器 [英] MD5 to text convertor

问题描述

使用vb6将MD5转换为文本字符串的任何人.
我正在跟踪将字符串转换为MD5哈希的链接
链接:使用VB创建和创建检查许可证密钥 [^ ]

anyone having the MD5 to text string converter using vb6.
I am following the link that will convert the string into MD5 hash
link: Using VB to Create & Check License Keys[^]

Private Const MyProductName ="Office Trainer"
 . . .
If Not (UserNameT = "") Or Not (ProdNameT = "") Then
  RawKey = GenKeyString(UserNameT, ProdNameT & MyProductName, FeatID)
  BinKey = HexStrToBinStr(RawKey)
  KeyCode = FormatKeyCode(Base32Enc(BinKey), 4)
Else
  KeyCode = "Please Enter Licensee and/or Serial Number;
End If
. . .

我拿到了Rawkey.现在我想使用MD5描述获取原始值.

I m getting the Rawkey. now i want to get the original value using MD5 description.

推荐答案

您不能. MD5不是一种加密机制，它是一种哈希算法.这就是所谓的不可逆过程.
考虑一下:MD5的长度为128位.
如果您使用256GB文件的MD5，则它的长度仍为128位.您将如何重新生成丢失的数据? (如果可以的话，请迅速申请专利-这种压缩值得 财富 )
如果同时需要两种方式，则需要加密算法.

You can''t. MD5 is not an encryption mechanism, it is a hashing algorithm. That means it is what is called a non-reversable process.
Think about it: and MD5 is 128 bits long.
If you take the MD5 of a 256GB file, it is still 128 bits long. How would you re-generate the missing data? (if you could do it, pattent it quickly - that kind of compression is worth a fortune)
If you need to go both ways, you need an encryption algorithm instead.
