Define: Symmetric encryption
a symmetric encryption algorithm uses a key (small string of data) to scramble a plaintext into a ciphertext. The ciphertext is not readable to anyone who does not have access to the key.

Relevant Circumstances
- When data must be protected in transit or at rest using shared-key cryptography
- If contractual security standards require specified algorithms or key lengths
- Where loss of the shared key could compromise confidentiality of customer data
