PasswordDeriveBytes.CryptDeriveKey derives an AES key but gets "Object identifier (OID) is unknown"

Question

Hi all,
I'm using PasswordDeriveBytes class to derive an AES cipher key with the following code:
            RNGCryptoServiceProvider rng = new RNGCryptoServiceProvider();
            byte[] salt = new byte[8];
            rng.GetBytes(salt);
            PasswordDeriveBytes pdb = new PasswordDeriveBytes(keyHash, salt);
            aes.Key = pdb.CryptDeriveKey("AES", "SHA1", 128, aes.IV);

however, it comes with an CryptographicException with the message: Object identifier (OID) is unknown
So what's the valid name for "AES" algorithm? I'm using AES 128. Thanks~

Answer 1

Is it that the .net wrapper doesn't support AES?

Answer 2

Problem solved. I disassembled mscorlib.dll, PasswordDerivedBytes.CryptDeriveKey does not support AES.
