In all of the examples so far in this chapter, when a secret key was necessary, it has been specified as an input parameter to the method. This is all well and good in the abstract, but somewhere in your program you will need to generate a good sequence of bytes to use as a random key for an encryption or keyed hash algorithm. How one generates good values to use as secret key material is the subject of this section. We now discuss two smaller portions of the cryptographic object hierarchy that are still extremely important to writing crypto-aware applications—random number generators and secret key derivation classes.
