Cryptography and Data Protection Questions

Focuses on cryptographic controls and operational practices used to protect data at rest and in transit and the practical trade offs of their deployment. Topics include symmetric and asymmetric encryption concepts; common algorithms and their properties; encryption in transit and at rest; transport layer security and certificate management; key management and lifecycle including generation, storage, rotation, and revocation; digital signatures and integrity checks; threat models and limitations of cryptography; performance and scalability considerations; and how cryptographic controls integrate with access control, logging, and incident response to meet data protection goals.
