An encryption scheme that combines symmetric-key and public-key (asymmetric) cryptography. The actual message is encrypted with a symmetric key for speed, and that symmetric key is then encrypted with the recipient's public key for secure delivery. This approach leverages the strengths of both methods, achieving both performance and secure key distribution.
