What is a Key Derivation Function?
John Spacey, updated on November 28, 2016
A key derivation function is an algorithm that generates a cryptographic key from a password or master key. They produce the same result every time for a given input such that it is possible to find the key from a given password. Passwords are potentially too weak to use directly in encryption. Key derivation functions are often used to create a longer and more random key from a password. This is technique is known as key stretching. Key derivation functions are commonly based on cryptographic hash functions or block ciphers and may make use of salt and pepper.
