  • Dear Nazir, I am trying to use M2 to decrypt our encrypted data. For M2's input we have: Key - The decryption Key, used in conjunction with the IV, if appropriate, to decrypt the supplied Message. Can you tell me the value for it is a variant, encrypted from LMK? Thanks a lot friend. – TienLuong Oct 10 '16 at 08:05
