WebPGP works through a combination of cryptography, data compression, and hashing techniques. It is similar to other popular encryption methods such as Kerberos, which authenticates network users, secure sockets layer (SSL), which secures websites, and the Secure File Transfer Protocol (SFTP), which protects data in motion. WebFigure 1. key encryption Symmetric key ciphers are valuable because: It is relatively inexpensive to produce a strong key for these ciphers. The keys tend to be much smaller for the level of protection they afford. The algorithms are relatively inexpensive to process. Therefore, implementing symmetric cryptography (particularly with
