java.lang.Object | +----javax.crypto.spec.DHParameterSpec
A central authority generates parameters and gives them to the two
entities seeking to generate a secret key. The parameters are a prime
p, a base g, and optionally the length
in bits of the private value, l.
It is possible that more than one instance of parameters may be generated by a given central authority, and that there may be more than one central authority. Indeed, each individual may be its own central authority, with different entities having different parameters.
