How do I encrypt a string in vb.net using RijndaelManaged, and using PKCS5 padding?

Question

I use the following code to initialize encryption...

 Dim symmetricKey As New System.Security.Cryptography.RijndaelManaged()
 With symmetricKey
   .Key = Enc         


        

Answer 1

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

EDIT:

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.
