Encryption
Definition
Encryption is a process that converts readable data (plaintext) into a scrambled format (ciphertext) that can only be decoded and read by someone with the correct decryption key. It's a fundamental security technique that protects information from being understood if intercepted by unauthorized parties.
Explain Like I'm 5
Encryption is like putting your secret message in a magic box that only your friend with the special key can open. It keeps your message safe from sneaky spies trying to read it.

Encryption uses algorithms to transform data into a secure form, ensuring confidentiality and privacy. It involves keys for encryption and decryption, with popular methods like symmetric and asymmetric encryption. Applications range from securing online transactions to protecting sensitive communications in government and healthcare sectors.
