Introduction to Encryption

Encryption is a critical technology in safeguarding digital information. It converts plaintext, which is readable data, into ciphertext, a scrambled format only accessible to those with the proper decryption key.

Fun Fact: The word "encryption" comes from the Greek word "kryptos," meaning hidden or secret.

Types of Encryption

• Symmetric Encryption: Uses the same key for both encryption and decryption.
• Asymmetric Encryption: Utilizes a public key for encryption and a private key for decryption.
