So now, I shall tell you the required information for the decryption. =)
Firstly, the matrices are arranged in 2X2 matrix form, M with the following order.
Top left for the first number, top right for the second number, bottom left for the third and bottom right for the fourth.
The encoding matrix, E is to be 2, 1, 13, 7 following the order as mentioned above.
And the encoding process,
The formula is Encoded matrix, C = 'inverse of E' multiply by 'M' and multiply by 'E'
After all, adjustments are needed if the elements calculated are not within the range of 1 to 26.
You are required to either add or subtract the elements by multiples of 26.
Lastly, the most important information!!!!
The code of the message is 22, 24, 19, 4, 26, 2, 23, 23, 25, 16, 25, 5, 8, 20, 20, and 15.
So, try to decode the message by using your knowledge about matrices. And after all, you will get the original message!! Have fun!!!=D
~Oh ya..for those who had succeeded in decrypting it..please feel free to let me know your success by leaving comments in comment box or the chat box beside. Thanks!!!=)~
