如何使用 RijndaelManaged 和 PKCS5 填充在 vb.net 中加密字符串? [英] How do I encrypt a string in vb.net using RijndaelManaged, and using PKCS5 padding?

问题描述

我用下面的代码来初始化加密...

I use the following code to initialize encryption...

 Dim symmetricKey As New System.Security.Cryptography.RijndaelManaged()
 With symmetricKey
   .Key = Encoding.ASCII.GetBytes(Key)
   .IV = Encoding.ASCII.GetBytes(IV)
   .Mode = CipherMode.CBC
   .BlockSize = 128 
   .KeySize = 128 
   .Padding = PaddingMode.PKCS7
End With

要求是使用 PKCS5.vb.net 中的填充模式仅包括

The requirement is to use PKCS5. Padding modes in vb.net only include

• ANSIX923
• ISO10126
• 没有
• PKCS7
• 零

所以我认为 PKCS5 没有方法.有什么办法可以添加，还是需要自己写一个加密方法?如果是这样 - 我该怎么写?是否有可靠的 DLL 支持它?

So I don't think there is a method for PKCS5. Is there any way to add it, or do I need to write an encryption method myself? If so - how do I write that? Is there a reliable DLL that will support it?

推荐答案

PKCS7 填充和 PKCS5 填充是一回事.在这种情况下，它们是同义词.

PKCS7 padding and PKCS5 padding are the same thing. In this context they are synonyms.

PKCS#7 填充在 PKCS#7 规范中描述第 10.3 节.PKCS#5 填充在 PKCS#5 规范的第 6.1.1 节中进行了描述步骤 4. 通过检查可以看到，填充算法是相同的.

The PKCS#7 padding is described in the PKCS#7 spec in section 10.3. PKCS#5 padding is described in the PKCS#5 spec in section 6.1.1 step 4. As you can see by examination, the padding algorithms are identical.
