hybrid encryption
(I) An application of cryptography that combines two or more
encryption algorithms, particularly a combination of symmetric and
asymmetric encryption. (E.g., see: digital envelope.)
(C) Asymmetric algorithms require more computation than
equivalently strong symmetric ones. Thus, asymmetric encryption is
not normally used for data confidentiality except in distributing
symmetric keys in applications where the key data is usually short
(in terms of bits) compared to the data it protects. (E.g., see:
MSP, PEM, PGP.)
