Windows store apps, Encryption,The supplied user buffer is not valid for the requested operation

Question

I am trying to implement a simple Encryption of a string.

I am getting "The supplied user buffer is not valid for the requested operation" error.

I am targeting Rindael Algorithm But currently I am using AesEcb.

I dont know what is the problem in the implementation.

Below is the code snippet.

var keyHash = GetMD5Hash(key);

var toDecryptBuffer = CryptographicBuffer.ConvertStringToBinary(toEncrypt, BinaryStringEncoding.Utf8);

var aes = SymmetricKeyAlgorithmProvider.OpenAlgorithm(SymmetricAlgorithmNames.AesEcb);

var symetricKey = aes.CreateSymmetricKey(keyHash);

var buffEncrypted = CryptographicEngine.Encrypt(symetricKey, toDecryptBuffer, null);

Answer 1

I'll ask our crypto guy to check this out.

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.
