Claim One:
1. A method of encrypting data and sending it from a sender to a receiver and decrypting it comprising: said sender sending a sender-selected-decipher, (which can be any kind of decryption method and can be one or more than one kind decryption methods) or part of it, (the other part of which can be known to the public and the receiver has it already in its system) using public key cryptographic method (PKI) or any other cryptographic method to said receiver to decrypt said set of data encrypted by said sender-selected-cipher, (which can be any kind of encryption method). From time to time said sender may send new sender-selected-decipher to said receiver to change cryptographic algorithm for increase security level so the cryptanalysts will have much more difficult breaking the code.
