  Since childhood, instead of playing with toys, I used to break toys to see what was in them. I was very interested in these things. I once opened and ruined a new watch the day I bought it. That day my mother scolded me for this. I used to watch attentively when the electricians fixed the TV or the fan. Then when I grew up, my interest in electronics started to grow. I used to make small fans and lights with motors, LEDs and batteries. To be honest, I've wasted more than I've made. After that I refrained from doing these things for many days. Then when I was in class 10, our school held a science fair. I saw a lot of interesting electronic gadgets out there . I was just watching without any  detailed knowledge or idea about them but my interest grew more and more. I didn't even know their names. Then after going to college, I got acquainted with electronic circuits and logic gates. And at the same time I got my first smartphone. I used to try to learn about them from Y...

         Have you ever heard of the Enigma Machine, one of the most famous cryptographic devices used by the Germans during World War II? It involves rotors and plugboards to replace characters multiple times, creating highly complex and variable encryption. Breaking the Enigma code was a significant achievement for cryptanalysts, including Alan Turing. If you love thrillers, have ever read any detective book, you must have seen Cipher. A cipher is a method or technique used to convert plain, readable text (known as plaintext) into a coded or unreadable form (known as ciphertext). This process is a fundamental aspect of cryptography. Cryptography has its roots in ancient civilizations. The Caesar cipher is one of the oldest known ciphers, created by Julius Caesar. Ciphers were widely used during World Wars I and II. In modern times, the concept of data encryption and decryption comes from this cryptography concept.
