Is RijndaelManaged key length the same as AES[key length]?
RijndaelManaged is an algorithm while AES is the standard. When referring to AES256, does that mean the key length I'm using with RijndaelManaged must be 256 characters?
If I have a key like this:
key = "mytestkey";
which is only 9 characters,…
