What is?
Encryption
The process of encoding data to make it unreadable without the correct decryption key.
Encryption ensures confidentiality of data at rest, in transit, and in use. Modern systems employ symmetric algorithms (AES) and asymmetric cryptography (RSA, ECC) alongside key management services.
- Symmetric vs. asymmetric encryption
- Transport Layer Security (TLS)
- End-to-end encrypted messaging
- Key rotation and lifecycle management
