What Is It?
PGP stands for
“Pretty Good Privacy” and is an encryption standard created by Phil
Zimmerman and first released in 1991. The protocol is used by Web browsers
and email programs to encrypt data before transmission over networks.
The recipient uses a private key to decrypt the data and to verify the
digital signature of the sender. PGP can also be used to encrypt stored
data. Originally offered as a freeware program, PGP has evolved into
both commercial and open source versions.
An alternative encryption technology is Secure
Sockets Layer (SSL),
a protocol developed for TCP/IP transmissions. Each SSL Certificate
is created for a particular Web server in a specific domain for a verified
business entity. Like a passport or a driver’s license, an SSL Certificate
is issued by a trusted authority. Digital IDs based on SSL can be installed
within email programs and Web servers to encrypt email communications
between individuals.
