such as encryption and decryption via the PKCS #11 interface. A PKCS #11 module
can be implemented in either hardware or software, and always contains one or
more slots. Each of these slots, which can be implemented physically in hardware
or conceptually in software, can contain a security device. Netscape Console
includes a built-in software PKCS #11 module.
port number A way to identify a specific process to which a network message is
to be forwarded when it arrives at a server.
private key One of a pair of keys used in public-key cryptography. The private
key is kept secret and is used to decrypt data encrypted with the corresponding
public key.
protocol
A set of rules that describes how devices on a network exchange
information.
public key
One of a pair of keys used in public-key cryptography. The public key
is distributed freely and published as part of a certificate. It is typically used to
encrypt data sent to the public key’s owner, who then decrypts the data with the
corresponding private key.
public-key encryption A set of encryption techniques that use a public key and a
private key.
