Message decipher
Cryptography is a field of science in which a sender encrypt information from outside world and then deliver through insecure medium. A person who work in secret intelligence, must share a his location with his friends so that they should complete their mission, or a person who know how to read ancient texts can protect information from some bad people.

The prefix "crypt" means "hidden" or "vault" and the suffix "graphy" stands for "writing."
Every writing system have one common property and that is "encoded message property". According to this property if you don't know how to read it then you don't know about key.
For example I write a line another language and check whether this property satisfy my hypothesis.

This is a message which i need to understand. There are two possibilities to understand this message
1. I know about every word and where to read (language rules)
2. I have a reference which guide me.

"Knowledge and man have relation" , I can decipher it easily because this my native tongue.
 However when old civilizations invade one another territory, Nations who win battle, abandon their civilization, destroy their engineering sites. Some of them also learn native.


First cipher had introduced by julius caesar, when cleopatra fallen in love with julius. Soldiers had search Cleopatra and julius everywhere. They introduce own method, so that they protect from soldiers and no one find them. More than 300 years their people understand what they say to each other. 
Holy cipher named as "atbash" which had found in Holy book Bible (Hebrew).     
Later 7 Century arab mathematician "Al Kundi" who introduce cryptography in mathematics field. First time mathematics serve for this purpose.
Al Kundi cryptography 

This is brief introduction of cryptography. Modern Cryptographist play with mathematics rules specially algebraic,number theory. However since the advent of computer cryptography techniques also enhance such as quantum security.

Rosicrucian cipher

In 1513 Cornelius Agrippa introduce early form Rosicrucian Cipher in his books Occult of Philosophy. Geometric and simple substitution cipher are well known ciphers      Pigpen , Freemason, Napoleon and tic tac toe ciphers in which alphabets or symbols arrange in grids.  This is an anagram, "How to reconstruct a data " lets encode the message.       Pigpen cipher , Rosicrucian and Tic tac toe Cipher                      Thank you have a good day.    


Golang provide  own enumerate method which is easy and very powerful. I will show you enumerate with in a sec. When i code enumerate in java, believe me i don't understand why it's used? So i never play from this card at that time, but recently when i start learning go. Now i used where it's used and why? Enumerate basically a counting method. Code   package main import ( " fmt " ) type Weekend int const ( Sunday Weekend = iota Monday Tuesday Wednesday Thursday Friday Saturday ) func main () { fmt. Printf ( " %d " ,Saturday) } If you remember adding color layer then you familiar from this code.  First i create my own type called weekend then used this type.  Iota-generator:   Things that confuse you Sunday Weekend = iota & Monday without value. Before we start Iota-generator first we understand monday without type or value         const ( c = 1 // c : 1 d      // d : 1 ) fmt.Pr

Every Object have a structure

If you start your programming career from c , then you know little about structs. Later Struct replace by classes in object oriented programming. However Go inherit from C. Structs :     With the help of structs, programmer can develop any type of structure         List        Stack        Queue        Trees        Graphs package main import ( " fmt " ) type Students struct { ID int Name string } var record Students func Id ( i int ) int { record. ID = i return record. ID } func Name ( name string ) string { record. Name = name return record. Name } func main () { var id int = 0 var name string = " ali " fmt. Println ( " id: " , Id (id), " name: " , Name (name)) } When we want to create custom type such as Celsius type Celsius float64, same with structs type Students structs except type need data type and in structs. You tells that's struct. Inside Structs
