The interface may be operatively connected to the memory and the processor and may communicate with the mobile device. This method uses a composition of two ciphers for re-encrypting the message at the intermediary, without revealing the plain text message or either cipher to the intermediary. The supporting elements define the once set radial position of the perforating knife.
