GLOSSARY / Encryption

What is Encryption?

Transforming data into an unreadable form so only authorized parties with the key can read it.

Symmetric encryption (AES) uses one shared key; asymmetric encryption (RSA, ECC) uses a public/private key pair. Encryption protects data in transit (TLS) and at rest.

Strong algorithms and proper key management are essential — weak crypto is CWE-327.
