In cryptography, a key derivation function (or KDF) derives one or more secret keys from a secret value such as a master key or other known information such as a password or passphrase using a pseudo-random function. Keyed cryptographic hash functions are popular examples of pseudo-random functions used for key derivation.

Famous quotes containing the words key and/or function:
“As soon as you are in a social setting, you better take away the key to the lock of your heart and pocket it; those who leave the key in the lock are fools.”
—Johann Wolfgang Von Goethe (1749–1832)
“Our father has an even more important function than modeling manhood for us. He is also the authority to let us relax the requirements of the masculine model: if our father accepts us, then that declares us masculine enough to join the company of men. We, in effect, have our diploma in masculinity and can go on to develop other skills.”
—Frank Pittman (20th century)
