ENCRYPTION AND DECRYPTION

When I was little, I used to play code games with my friends. It was nothing more than just converting the actual word into a set of symbols or another alphabet. That game will be very fun to play. During free periods in school, we played this game; that’s how I developed an interest in encryption. During my high school days, I developed the practice of writing personal diaries in encrypted codes. My high school computer teacher told us to find out about encryption. That is when I started searching about encryption and decryption. In this blog, I discussed encryption and decryption known to my knowledge.

The conversion of human-readable plain text into incomprehensible text is called encryption of data. The data can be accessed only by a person with the key for decryption. The conversion of encrypted data to human-readable text is known as the decryption of data. This method is widely used in messenger apps and to carry highly confidential information.

The most common application that uses this method is WhatsApp Messenger. You may have noticed that on top of your chat, there will appear a message that your messages are end-to-end encrypted. This means that your chat is encrypted with a certain key and is decrypted only for the person you are sending it to. This method was brought into practice so that it would not be hacked easily. Each and every chat has a different encryption key, so our messages will be safe.

If you wish to play with encrypted code, there are many websites for it; one of the safest is https://kids.nationalgeographic.com/games/action-adventure/article/crack-the-code-1 . So don’t just use technologies; analyze them, and you will gain knowledge.
