694 GLOSSARY
pre-master secret A key generated during the handshake process in Transport Layer
Security (TLS) protocol negotiations and used to derive a master secret.
preshared key See PSK.
PRF Pseudorandom function. A function that produces effectively
unpredictable output. A PRF can use multiple iterations of one or more
hash algorithms to achieve its output. The Transport Layer Security (TLS)
protocol defines a specific PRF for deriving keying material.

Mail
See PEM.
private key In cryptography, one of a pair of keys, one public and one private, that
are created with the same algorithm for encrypting and decrypting
messages and digital signatures. The private key is provided to only the
requestor and never shared. The requestor uses the private key to
decrypt text that has been encrypted with the public key by someone
else. See also PKI; public key.
PRNG Pseudorandom number generator. An algorithm of predictable behavior
that generates a sequence of numbers with little or no discernible
order, except for broad statistical patterns.
