The result of this function is
Then I tried to decrypt the value using an online tool, but I always received an error message.
I suppose there is a difference between AES algorithm in Marketing Cloud and AES used in the online tool. Indeed if I encrypt the same word with an online tool (128-bit), I received this result
Do you have any deep information regarding this function? What could be the difference?
