Generate Random AES Encryption Key

I was looking for a way to quickly generate a random AES key online, but couldn't find anything. I looked into a couple methods using JavaScript, but determined that a C# solution would be better.

I needed to base64 encode the key array to store that value in a config file.

Here's the code I ended up with:


Using Visual Studio's "C# Interactive" screen you can generate a key in a single line:

var keyArray = new byte[32]; (new System.Security.Cryptography.RNGCryptoServiceProvider()).GetBytes(keyArray); Convert.ToBase64String(keyArray)

Hope this helps!
