如何使用RijndaelManaged加密vb.net中的字符串,并使用PKCS5填充? [英] How do I encrypt a string in vb.net using RijndaelManaged, and using PKCS5 padding?
问题描述
我使用以下代码初始化加密...
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中的填充模式只包括
The requirement is to use PKCS5. Padding modes in vb.net only include
- ANSIX923
- ISO10126
- 无
- PKCS7
- 零点
- ANSIX923
- ISO10126
- None
- PKCS7
- Zeros
所以我不认为PKCS5有一个方法。有没有办法添加,还是需要自己编写加密方法?如果是这样 - 怎么写?有没有可靠的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.
编辑:
PKCS#7填充在第10.3节中的PKCS#7规范。 PKCS#5填充在6.1.1节中的 PKCS#5规范中有描述通过考试可以看出,填充算法是一样的。
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.
