What is RSA Encryption?
RSA encryption is a type of cryptography that helps in locking and unlocking these digital. boxes. It’s named after its inventors: Rivest, Shamir, and Adleman
How Does RSA Work?
Keys: RSA uses two keys — a public key and a private key.
oPublic Key: This is shared with everyone. It’s like the lock on the box.
oPrivate Key: This is kept secret. It’s like the key that can unlock the box
Step-by-Step Example
Meet Alice and Bob:
o Alice wants to send a secret message to Bob.
o Bob has a public key (which he shares with everyone) and a private key
(which he keeps secret).
- Alice Encrypts the Message
o Alice writes her message, “Hello Bob!”
o She uses Bob’s public key to encrypt the message.
o The encrypted message looks like a bunch of random letters and numbers.
- Bob Decrypts the Message:
o Bob receives the encrypted message.
o He uses his private key to decrypt it.
o Bob can now read the message, “Hello Bob!

Why is RSA Important?
Security: It keeps your messages and data safe from hackers.
Privacy: Only the intended recipient can read the message.
Authentication: It can also be used to verify that the sender is who they say they are.
Fun Facts About RSA
Big Numbers: RSA encryption relies on very large prime numbers, making it extremely difficult to crack.
. Daily Use: It’s used in many everyday applications like online banking, secure emails, and even some messaging apps.
. History: It was first introduced in 1977 and remains one of the most widely used encryption methods today.
Conclusion
End-to-end encryption using RSA ensures your digital life stays private and secure. By using public and private keys, it creates a secure environment for communication and data transfer. Next time you send a message, you can feel confident knowing that RSA encryption is working behind the scenes to keep it safe!
