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.
| Constructor Summary | |
| DHParameterSpec(java.math.BigInteger p,
java.math.BigInteger g)
Specifies the Diffie-Hellman parameters, using a prime modulus p and a base generator g. |
|
| DHParameterSpec(java.math.BigInteger p,
java.math.BigInteger g,
int l)

and the size in bits, l, of the random exponent
(private value). |
