Cryptography is the practice of securing information by converting it into a code that can only be read by those who have the key to decrypt it. Encryption and decryption are the two fundamental processes of cryptography, and understanding how they work is crucial for anyone looking to secure their digital communications.

In this blog post, we’ll provide a beginner-friendly introduction to the world of cryptography, including an overview of common encryption and decryption techniques. We’ll explore how cryptography works to keep data secure, as well as some of the key challenges and limitations of these techniques.
