File Encryption

Encryption

Data Encryption at Rest Secure Storage Encryption Key

Per-file encryption using symmetric or hybrid schemes.

Definition

File encryption applies cryptographic transforms to file contents and often metadata, using symmetric keys, sometimes wrapped with public-key encryption for sharing.

In plain English Per-file encryption using symmetric or hybrid schemes.

Why this matters

Why it matters: It limits data exposure in storage and during file transfers when properly key-managed.

Example

Example: AES-encrypted archive with key exchange via public-key cryptography.
