Simple hill cypher

Nowadays people like keeping  things secret and secure, this is most commonly done with cryptography. This is not only used for emails, and instant messages, it can also be used for good old fashion letters in which the people communicating have a legend to decrypt the message sent.

Next we would convert the message into a 3X1 matrix.

                        9        9        0        20

                        0        11        13        8

                        12        5        1        21

We would then multiply this matrix with the encoding matrix to incode it:

                        1        0        0

                        0        2        0

                        0        0        2

Conclusion

Even though the new programs developed to crack encryptions, cryptography still remains one of the safest encryption methods. Certain programs are reliable but they can easily be cheated by expert crackers, due to there repetitiveness, unlike a human which can think of a new encryption every time.

Finally, you have learnt a simple form of encryption, have fun experimenting with friends I hope it will serve you in your future.
