WebPGP is a software encryption suite initially created in the 1990s that can perform both asymmetric encryption (such as using RSA key pairs) and symmetric encryption (which is faster or "stronger" but less convenient). In practice, PGP or similar software will attempt to hide away the complexity of the underlying process - which is pretty complex.
