Isn't this a 256 bit key and IV since its 32 chars in length?
Well, 32 hex chars = 16 bytes (2 hex chars per byte) = 128 bit
Consequently, 256-bit key would be 64 characters in hex encoding.

Hello,
I am trying to use this but with AES-256. Isn't this a 256 bit key and IV since its 32 chars in length?
