Abstract
A computerized system and method for symmetric encryption and decryption using two machines, the method including obtaining a message and an initialization vector on a first machine, sending the initialization vector to a second machine, where said second machine stores an encryption key for a Key Derivation Function (KDF), generating a derived key on the second machine by applying the KDF receiving as input both the encryption key and the initialization vector, sending the derived key from the second machine to the first machine, and encrypting the message using the derived key on the first machine.
