Introduction: Secrets in the Code

Every time you send a message, make an online purchase, or log into your email, there’s a silent guardian working behind the scenes: mathematics.

From WhatsApp chats to bank transfers, the digital world relies on cryptography — the ancient science of keeping secrets. But unlike spies with invisible ink, today’s secret-keepers use complex math to lock data away from prying eyes.

In this blog, we’ll uncover how mathematics powers modern cryptography, turning numbers into armor that protects our online lives.

Keywords: Cryptogrphy, Encryption, Decryption, Internet security, RSA Algorithm.
