Really simple encryption with C# and SymmetricAlgorithm

Question

I\'m looking for a very simple crypt / decrypt method. I will be using always the same static key. I\'m aware of the risks of this approach. Currently I\'m

Answer 1

You'll need to set the cipher mode to CipherMode.ECB or use an IV.

SymmetricAlgorithm symmetricAlgorithm = DES.Create();
symmetricAlgorithm.Key = new byte[8] { 1, 2, 3, 4, 5, 6, 7, 8 };
symmetricAlgorithm.Mode = CipherMode.ECB;
...

Another point is not to use Unicode encoding. Use Base64 instead. Unicode might "destroy" bytes that are not UTF-16.
