In many applications, the high cost of encrypting long messages in a public-key cryptosystem can be prohibitive. A hybrid cryptosystem is one which combines the convenience of a public-key cryptosystem with the efficiency of a symmetric-key cryptosystem.A hybrid cryptosystem can be constructed using any two separate cryptosystems: a key encapsulation scheme, which is a public-key cryptosystem, and a data encapsulation scheme, which is a symmetric-key cryptosystem.The hybrid cryptosystem is itself a public-key system, whose public and private keys are the same as in the key encapsulation scheme.Note that for very long messages the bulk of the work in encryption/decryption is done by the more efficient symmetric-key scheme, while the inefficient public-key scheme is used only to encrypt/decrypt a short key value.Perhaps the most commonly used hybrid cryptosystems arethe OpenPGP (RFC 4880) file format and the PKCS #7 (RFC 2315) file format,both used by many different systems."@en }
