• Encryption

  • way of scrambling data so that only authorized parties can understand the information.
• At rest

  • Data can be encrypted, when it is stored.
• in transit

  • hile it is being transmitted somewhere else
• cryptographic key

  • is a string of characters used within an encryption algorithm for altering data so that it appears random
• cryptographic key

  • is a string of characters used within an encryption algorithm for altering data so that it appears random
• physical key

  • it locks (encrypts) data so that only someone with the right key can unlock (decrypt) it.
• Privacy

  • encryption ensures that only authorized individuals can. access communications or stored data
• Security

  • By encrypting data during transmission or while at rest, encryption helps prevent data breaches
• Data Integrity

  • encryption helps safeguard against malicious tampering during data transmission
• Authentication

  • encryption relies on keys, ensuring that only authorized recipients can decrypt and access the contents of a message.
• Symmetric Encryption

  • the same key is used for both encryption and decryption.
• Caesar cipher

  • One of the simplest and most basic forms of symmetric encryption that can be done manually is the
• ciphertext

  • it is the process of converting human-readable plaintext to incomprehensible text,
