What is the difference between encryption at rest and encryption in transit?
A.Encryption at rest is faster; encryption in transit is more secure
B.Encryption at rest protects stored data (files on S3, DB rows on disk); encryption in transit protects data moving between systems (API calls, DB connections) using TLS/SSL
C.Encryption at rest is optional; encryption in transit is mandatory
D.They use different keys but protect the same data
