The present invention relates to a method of encrypting and transferring data between a sender and a receiver using a network thereby transferring data in a secure manner. The method comprises the steps of a server receiving from the sender an identifier of the receiver (S 4 A, S 4 B); establishing a transfer specific encryption key specific to the transfer (S 7 B); encrypting the data using the transfer specific encryption key (s 8 B); the server accessing receiver specific information according to the received identifier of the receiver and encrypting, with the receiver specific information, said transfer specific encryption key (S 11 B); transferring the encrypted data and the encrypted transfer specific encryption key over the network for receipt by the receiver (S 11 B); the server receiving from the receiver the encrypted transfer specific encryption key; the server accessing the receiver specific information to decrypt the encrypted transfer specific encryption key; and decrypting the encrypted data using the decrypted transfer specific encryption key.
