This document specifies a simple Hashed Message Authentication Code
(HMAC)-based key derivation function (HKDF), which can be used as a
building block in various protocols and applications.  The key
derivation function (KDF) is intended to support a wide range of
applications and requirements, and is conservative in its use of
cryptographic hash functions.  This document is not an Internet 
Standards Track specification; it is published for informational
