Figure what out?  Any crypto written in JavaScript is insecure.  Data should be encrypted and decrypted on the server which you have working at this time.

Hi,

keySize seems different and BlockSize casing wrong for example. Do you have an encrypted value and the value we are supposed to find? If on my own I would try to both encrypt/decrypt in js to see first if I'm consistent on this side and then if it matches what I find on the C# side.

As pointed already it could be better to make sure you'll really need that before making this to work. You try to protect what ?

Hey,

as a c# 

1. my object is encText = {"encText": "sample"}
2. secret key is "7YIOB9NooY225lP6CRSqKQ0KiluAF/6cYn3kFXvJkS0=";
3. and my encrpted text is "P+KvsN/m3qOc8egIkqyi4w=="

just try to protect my data object. So as a javascript side i get ecrypted text and key, try to react decrypted data object.</div>
