Encryption التشفير

Definition

Mathematically scrambling data so only key holders can read it. In hosting it appears in two forms: encryption in transit (TLS protecting traffic) and encryption at rest (disk or database-level protection of stored data). AES-256 is the symmetric workhorse; RSA and elliptic curves handle key exchange. Compliance regimes like PDPL and GDPR expect both forms.
